- Subject: -1- Where can I find software for SGIs?
- Date: 4 Nov 1998 00:00:01 EST
-
- Silicon Graphics can tell you about their own and third-party
- commercial software. Call SGI Direct for more information (see the
- misc FAQ for phone numbers) or look around on SGI's WWW server,
- Silicon Surf (http://www.sgi.com/ or its mirrors; see the misc FAQ),
- particularly under "Surf Shop" and "Subsidiaries and Partners".
-
- The best general reference for finding sources on the Internet is
- Jonathan Kamens' "Finding Sources" document. It can be FTPed from
- ftp://rtfm.mit.edu/pub/usenet/news.answers/finding-sources. Read it
- carefully before you post a question about finding software ...
- because half of your answers will be "look in Archie" anyway, and
- "Finding Sources" tells you how to do that.
-
- Useful general archive sites include ftp://ftp.x.org/ for X software
- (particularly in the /contrib and /R5contrib directories) and X itself
- (in /pub), ftp://prep.ai.mit.edu/pub/gnu/ for GNU software, and
- ftp://ftp.uu.net/ and ftp://wuarchive.wustl.edu/ for nearly anything,
- including archives of many Usenet sources newsgroups and mirrors of
- the aforementioned GNU and X archives.
-
- The best SGI-specific reference is Bill Henderson's
- <billh@hampton.sgi.com> SGI anonymous FTP list. (Look in the misc FAQ
- under "WWW pages" and "network-accessible documents".) Good places to
- look, if you just feel like looking, are ftp://ftp.sgi.com/ and
- ftp://sgigate.sgi.com/, where are kept any number of freebies from the
- folks at SGI, http://www.sgi.com/Fun/free/, a collection of freeware
- from SGI and elsewhere, and ftp://swedishchef.lerc.nasa.gov/, a site
- particularly well-stocked with SGI-related materials.
-
- SGI publishes a freeware CD-ROM with sources and binaries for popular
- free software; it is included with new systems and its most recent
- versions are available on the web at http://freeware.sgi.com/ which
- is updated frequently.
-
- Finally, see the next question for places to find precompiled
- software and questions (in this and the other SGI FAQs) which discuss
- particular packages for pointers to those packages.
-
- ------------------------------
-
- Subject: -2- Where can I find software already compiled for SGIs?
- Date: Wed Sep 22 14:11:20 CDT 1999
-
- ftp://cb-iris.stanford.edu/pub/ *
- ftp://detritus.phys.wesleyan.edu/pub/
- ftp://ftp.uni-stuttgart.de/sw/
- ftp://mat075402.student.utwente.nl/pub/SGI/ *
- http://mat075402.student.utwente.nl/pub/SGI/index.html *

- http://www.madness.net/sgi.html
- http://www.pk.edu.pl/pub/sgi/ *
- http://www.sgi.com/Fun/free/ *
-
- are good places to try. (At least some of the software at the sites
- marked with `*' is not only precompiled but packaged so that you can
- install it with 'inst' and/or 'swmgr'.) If all else fails, check Bill
- Henderson's list (see the misc FAQ). Keep in mind that many of these
- binaries won't be the latest version, and it's worth checking the
- latest version to see if IRIX support has improved. SGI's presence is
- continuously increasing and the trend is definitely toward better IRIX
- support.
-
- ------------------------------
-
- Subject: -3- What about Explorer?
- Date: 04 Aug 1995 00:00:01 EST
-
- The IRIS Explorer data visualization system has its own newsgroup,
- comp.graphics.apps.iris-explorer. There is an FTP site at
- ftp://ftp.epcc.ac.uk/pub/explorer/ (with a North American mirror at
- ftp://swedishchef.lerc.nasa.gov/explorer/), a WWW page at
- http://www.nag.co.uk:70/1h/Welcome_IEC and an FAQ which you can find
- at any of those sites.
-
- ------------------------------
-
- Subject: -4- WHAT TO USE?
- Date: 10 Dec 1993 00:00:01 EST
-
- The next few questions discuss software for various applications.
-
- ------------------------------
-
- Subject: -5- Where's the C compiler?
- Date: Mon May 22 11:49:44 CDT 2000
-
- For IRIX 5.3, IDO is now available on the web free. See
- http://www.sgi.com/developers/devtools/apis/ido.html
- Complete with C compiler, headers, libraries, and tools.
-
- For IRIX 6.2-6.4, one needs IDF/IDL plus a compiler. Purchase a
- C compiler from SGI (IDF/IDL come with the compiler) or download
- IDF/IDL (and gcc) for free. IDF/IDL images for 6.2, 6.3, 6.4 are
- at http://www.sgi.com/developers/devtools/apis/idf_idl.html
- Get gcc from http://freeware.sgi.com/ to have a free C compiler.
-
- For IRIX 6.5, one needs IDF/IDL plus a compiler. IDF and IDL are
- shipped with IRIX6.5. Purchase a C compiler from SGI and/or get
- gcc for free from http://freeware.sgi.com/.
-
- ------------------------------
-
- Subject: -6- What's a good graphical text editor for SGIs?
- Date: 24 Aug 1996 00:00:01 EST
-
- The most popular graphic text editors on SGIs include:
-
- IRIX 5.x includes jot, which is very nice. It requires GL, i.e. no
- X-terminals, text terminals or non-SGI machines. See below for a bug
- and workaround. zip is the IRIX 4.x incarnation of jot (the jot which
- comes with IRIX 4.x is something else entirely); FTP it from
- ftp://ftp.sgi.com/graphics/zip/.
-
- nedit is a straightforward graphical editor with programmers'
- features. It needs X-windows but not GL. Get it from
- ftp://ftp.fnal.gov/pub/nedit/, and see also
- http://www-pat.fnal.gov/nirvana/nedit.html.
-
- GNU Emacs, a perennial favorite, isn't just an editor; it's a way of
- life. It has a X-windows mode and works on X-windows terminals as
- well as SGI consoles and text terminals. Its X-windows support, once
- rather lackluster, has improved in the recently released version 19.
- It may be FTPed from any GNU archive, e.g.
- ftp://prep.ai.mit.edu/pub/gnu/.
-
- XEmacs (formerly Lucid Emacs) is a derivative of GNU Emacs 19. It has
- subsumed Epoch, another derivative of GNU Emacs. It may be found in
- ftp://cs.uiuc.edu/pub/xemacs/, and it has a WWW page at
- http://xemacs.cs.uiuc.edu/. It works on both text and graphics
- terminals.
-
- Finally, the comp.windows.x FAQ (at
- ftp://rtfm.mit.edu/pub/usenet/comp.windows.x/) lists many more editors
- which run under X-windows, both free and commercial.
-
- ------------------------------
-
- Subject: -7- What's a good mail program for SGIs?
- Date: 18 Jun 1995 00:00:01 EST
-
- Z-Mail is a commercial product written by Z-Code and redistributed by
- SGI. IRIX 5.x includes MediaMail, a subset of Z-Mail. Both are
- graphical, MIME-compatible (MIME, described in RFC1521, is a standard
- for enclosing multimedia material in your mail) and have a text-only
- mode.
- ftp://viz.tamu.edu/pub/sgi/software/mail/zmail-vs-mediamail.ps.gz
- describes the differences between Z-Mail and MediaMail. Z-Mail has its
- own WWW site (http://www.ncd.com/Z-Code/zcode.html) and newsgroup
- (comp.mail.zmail).
-
- The free programs Elm and Pine use text-based menus. They are easy to
- use, powerful and can easily be run in a separate window. They can be
- configured to use 'metamail' for MIME support. Elm can be FTPed from
- ftp://dsinc.dsi.com/elm/, Pine from ftp.cac.washington.edu:/pine/ and
- 'metamail' from ftp://thumper.bellcore.com/pub/nsb/. Z-Mail/MediaMail
- includes 'metamail', so if you use both Z-Mail/MediaMail and Elm or
- Pine or another free mail program, you can save yourself some trouble
- by configuring the latter to use the former's 'metamail'. Elm has an
- FAQ in ftp://rtfm.mit.edu/pub/usenet/comp.mail.elm/. Packages which
- make Elm work nicely with IRIX 4.0.x's WorkSpace and IRIX 5.2's Indigo
- Magic are at ftp://proton.chem.yale.edu/pub/elm-ws-support.shar and
- ftp://proton.chem.yale.edu/pub/elm-im-support.shar. Elm's autoreply/
- arepdaemon subsystem has a bad security hole, so don't install those
- binaries. (They have been removed from v. 2.4.24 and later.) The rest
- of Elm is fine. Both programs have newsgroups, comp.mail.elm and
- comp.mail.pine.
-
- 'mh' is a free, command-line oriented Mail Handling system. FTP the
- source code from ftp://ftp.ics.uci.edu/pub/mh/ and patches for IRIX
- from ftp://viz.tamu.edu/pub/sgi/software/mail/. If you build 'mh' you
- can use 'xmh', a graphical mailer, which is part of Xwindows and thus
- comes with IRIX. 'mh' has a newsgroup, comp.mail.mh.
-
- Finally, Chris Lewis' "Unix Email Software - a Survey" lists many
- more mail programs. FTP it from
- ftp://rtfm.mit.edu/pub/usenet/news.answers/mail/setup/unix/.
-
- ------------------------------
-
- Subject: -8- What's a good POP server for SGIs?
- Date: 17 Feb 1996 00:00:01 EST
-
- Try the Berkeley popper, under http://www.ibd.nrc.ca/~sgi/, the
- Qualcomm popper, in ftp://ftp.qualcomm.com/quest/unix/servers/popper/,
- the Z-Code popper, in ftp://ftp.ncd.com/pub/z-code/supported/z-pop/,
- or imapd (which supports pop2 and pop3) in
- ftp://ftp.cac.washington.edu/mail/. Some info is at
- http://www.sgi.com/Technology/Connectivity/pop.html. On a related
- note, some ports of poppassd (a POP password changing daemon) to IRIX
- 5.3 are in ftp://viz.tamu.edu/pub/sgi/software/mail/.
-
- ------------------------------
-
- Subject: -9- Can I use MediaMail with a POP server?
- Date: 09 Dec 1995 00:00:01 EST
-
- Walter Roberson <roberson@hamer.ibd.nrc.ca> writes:
-
- Under IRIX 5.2, set the environment variable MAILHOST to the name of
- the mail server, and set the zmail variable 'use_pop'. You may also
- wish to set the zmail variable 'pop_options' to have mail retained on
- the server. Your userids on the machine with MediaMail and on the POP
- server must be the same.
-
- Under IRIX 5.3 all of the above still applies as well as the
- following: You can set the zmail variable 'mailhost' instead of the
- environment variable MAILHOST. You can set the zmail variable
- 'pop_user' to your userid on the POP server if it is different from
- your local userid.
-
- Note that MediaMail, like any POP client, cannot send mail to the POP
- server, only retrieve mail which has been sent to the server. That's
- just fine; doing the above doesn't prevent MediaMail from delivering
- mail normally.
-
- "Digital Media Execution Environment and Tools 5.5", at
- http://www.sgi.com/Products/Evaluation/dmedia/dmedia.html, includes an
- updated version of MediaMail for IRIX 5.3.
-
- ------------------------------
-
- Subject: -10- What's a good graphical 'diff' (side-by-side file
- comparison) program for SGIs?
- Date: Tue Dec 7 10:04:06 CST 1999
-
- gdiff(1) has been a part of IRIX for many years. It requires GL. It is
- SGI-proprietary and was written using a now-obsolete UI toolkit, so
- its source isn't available and you wouldn't want it anyway.
-
- 'xdiff' first appeared on the second IndiZone CD. It is not to be
- confused with the much less useful program of the same name posted to
- comp.sources.x some years ago. The IndyZoneII version of xdiff is
- now part of IRIX. A newer version of 'xdiff', capable of more
- than two files, is available from http://reality.sgi.com/rudy/xdiff.
-
- 'mgdiff' is a gdiff lookalike based on X11 and Motif, written by Dan
- Williams <dan@sass.com>. It is in the X11R6 contrib stuff, at
- ftp://ftp.x.org/contrib/applications/mgdiff.tar.gz among other places.
-
- ------------------------------
-
- Subject: -11- What's a good calendar/reminder program?
- Date: 06 May 1995 00:00:01 EST
-
- SGI doesn't provide one. There are several free graphical calendars
-
- acal On the second IndiZone CD (IndiZone info is at
- http://www.sgi.com/Products/Indy/IndiZone/)
- lowcal ftp://ftp.netcom.com/pub/benoist/sgi/
- plan ftp://ftp.fu-berlin.de/pub/unix/graphics/plan/
- vcal ftp://ftp.sgi.com/sgi/vcal/
-
- and a text-only reminder program
-
- remind ftp://ftp.doe.carleton.ca/pub/remind-3.0/
-
- which work on SGIs. They're all good; try them out and see which you
- like best.
-
- ------------------------------
-
- Subject: -12- What is a good serial communications application?
- Date: Mon May 22 15:59:47 CDT 2000
-
- C-Kermit is a combined serial and network communication software
- package providing online sessions, file transfer, international
- character-set translation, numeric and alpha paging, full scripting
- of communications tasks. As of the time of writing, the current
- version is 7.0 and is available precompiled for IRIX releases from
- 5.3 to 6.5. Previous versions are avaiable for earlier IRIX releases.
-
- http://www.columbia.edu/kermit/ckermit.html.
-
- ------------------------------
-
- Subject: -13- How can I convert ASCII to PostScript?
- Date: 19 Jun 1994 00:00:01 EST
-
- - IRIX comes with 'lptops', which, because it's called indirectly
- from 'lp', isn't as well known as it ought to be. Read the lptops(1)
- and gpsinterface(1) manpages.
-
- - Adobe Transcript, which includes 'enscript' (something like
- 'lptops') and 'psroff' (nroff/troff-to-PostScript) is available at
- extra cost from SGI. Most people manage without it.
-
- - SGI's own Impressario does PostScript and a lot of other things. It
- too costs extra, but is better liked than Transcript. See the
- impressario FAQ.
-
- - Popular free converters include 'a2ps' (at
- ftp://imag.fr/archive/postscript/), 'lwf' (in volume 15 of
- comp.sources.unix, e.g.
- ftp://ftp.uu.net/usenet/comp.sources.unix/volume15/lwf/) and 'psf'
- (in volume 35 of comp.sources.misc, e.g.
- ftp://ftp.uu.net/usenet/comp.sources.misc/volume35/psf3/). The
- comp.lang.postscript FAQ (at
- ftp://rtfm.mit.edu/pub/usenet/comp.lang.postscript/) has a much
- longer list of such programs, unfortunately no longer including
- reviews or FTP sites.
-
- - One good way to print manpages is with the '-m' option to 'a2ps'.
-
- ------------------------------
-
- Subject: -14- How can I preview PostScript?
- Date: 11 Feb 1995 00:00:01 EST
-
- In one of two ways:
-
- Display Postscript (DPS) comes with IRIX 5.x. (Machines which came
- with IRIX 4.0.1-4.0.4 didn't get DPS in later versions of IRIX 4.x,
- but it is standard in 5.x.) It includes the 'xpsview' viewer. The DPS
- developer's option, which you need to write or build programs which
- exploit DPS, costs extra.
-
- Ghostscript is free from Aladdin Software and the Free Software
- Foundation; ghostview (a viewer which uses ghostscript) is likewise
- free from the FSF. Original sources are in
- ftp://ftp.cs.wisc.edu/pub/ghost/, and Robert Keller of SGI
- <rck@fangio.asd.sgi.com> has put a compiled, 'inst'-installable
- package at ftp://ftp.sgi.com/sgi/ghost/.
-
- Dale Atems <atems@physics.wayne.edu> points out: Many people try
- ghostscript and give it up because of the fonts. There is something
- about ghostscript that's not as widely known as it should be and
- deserves emphasis: if you have SGI's Display Postscript, you can
- forget about most of the ugly bitmap fonts that come with
- ghostscript. Edit your Fontmap file to point ghostscript to the DPS
- outline fonts (in /usr/lib/DPS/outline/base) and it will use them
- instead. This will improve both screen display and, if you're not
- using a Postscript printer with those fonts already built in,
- printing quality. [Editor's note: This seems to cause problems with
- some files under IRIX 5.x. Any details?]
-
- ------------------------------
-
- Subject: -15- How can I edit PostScript files?
- Date: 16 Sep 1995 00:00:01 EST
-
- Ivan Bach <ib@sgi.com> collected some testimonials from a number of
- SGIers:
-
- - Adobe Illustrator and Corel Draw can edit PS files of type AI (a
- simplified version of PS that facilitates editing).
-
- - Transverter (from TechPool, 212-291-1922) can convert some general
- PostScript files to AI PostScript. It also does other conversions,
- e.g. to TIFF.
-
- - If you have DPS and the DPS developer's kit you can do this quite
- well with xfig. Check out the version in
- ftp://ftp.x.org/contrib/R5contrib-fixes/xfig-patches/.
-
- - The InterViews tool `idraw' allows manipulation of EPS
- (Encapsulated PostScript) files, and has a `mac-type' interface.
-
- - Island Draw 3.0 has an option to import Postscript, and it seems to
- accept arbitrary Postscript. I have fed it single page Postcript
- files from Illustrator, Corel, Ventura, Designer, Eroff, and
- hand-coded files, and it made Island Draw objects out of them. The
- file initially opens as one grouped object, but if you ungroup, you
- get editable objects. I was quite impressed. I don't doubt there
- are ways to fool the interpreter, but it works for output from
- drawing and publishing packages, which is what I need it for.
-
- - Jack Howarth <howarth@nitro.med.uth.tmc.edu> adds: ps2ai.ps converts
- Postscript to AI Postscript. It requires ghostscript (see above).
- aimaker is a front end to ps2ai.ps. Both programs can be found in
- ftp://toby.princeton.edu/pub/olszewsk/.

- Subject: -17- How can I format unformatted manpages?
- Date: 20 Jul 1996 00:00:01 EST
-
- SGI provides manpages in formatted form, and does not therefore
- provide us all with the formatting software. Most FTPable manpages,
- however, come in nroff ("unformatted") form.
-
- To install an unformatted manpage, one needs to format it (more on
- this in a moment), pack it with pack(1) and put it in the appropriate
- place under one of the 'catman' directories (see man(1)).
- Alternatively, one might simply put the unformatted manpage under one
- of the 'man' directories (again, see man(1)) and let IRIX run the
- formatting software on it as needed. Which method one uses is a matter
- of taste. In any case, one needs formatting software, and that is what
- the rest of this entry is about.
-
- Manpages are most often formatted with 'nroff', which is a part of
- Documenter's Workbench (DWB), which SGI has had to license separately
- from USL and we have to buy separately from SGI. SGI's DWB is based
- on version 2.1; the current version from USL is 3.3.
-
- You might be able to format manpages on a non-SGI machine which does
- have DWB/nroff. You might need to specify the generic printer macros
- with '-Tlp', e.g. 'nroff -man -Tlp foo.1 > foo'.
-
- Public domain alternatives to DWB include 'awf' and 'groff':
-
- Henry Spencer's awf ("Amazingly Workable Formatter") is written in
- 'awk', which we all have, and does a pretty good job, considering. It
- can be FTPed from ftp://ftp.sgi.com/sgi/IRIX5.0/man/, along with a
- version of 'man' which looks for awf if nroff isn't available. It will
- come with releases of IRIX after 5.3. Dan Stromberg
- <strombrg@hydra.acs.uci.edu> notes that there is a C version of 'awf'
- called 'cawf' which may be preferable; we don't know if it runs on
- IRIX.
-
- 'groff' is by the Free Software Foundation and can be had from any GNU
- archive (e.g. ftp://prep.ai.mit.edu/pub/gnu/). Compilers beware: it
- must be compiled with g++ or SGI's C++. However, there are compiled
- binaries in ftp://cb-iris.stanford.edu/pub/gnu/. David Hinds
- <dhinds@allegro.stanford.edu>, the man who put them there, gives this
- advice for installing groff so that it can format manpages on the fly
- in IRIX 4.0.x:
-
- Create a script called 'eqn':
-
- > #!/bin/sh
- > if [ ${1:-""} = /usr/pub/eqnchar ] ; then shift ; fi
- > geqn $*
-
- and a script called 'neqn':
-
- > #!/bin/sh
- > if [ ${1:-""} = /usr/pub/eqnchar ] ; then shift ; fi
- > geqn -Tascii $*
-
- and do:
-
- > ln -s gnroff nroff
-
- and edit the end of the gnroff script to be:
-
- > rest=`echo ${1+"$@"} | sed -e 's+/usr/lib/tmac+/usr/local/lib/groff/tmac+'`
- > exec groff -Wall -mtty-char $T $opts $rest
-
- To get PostScript output from 'man -t', you also need to create a
- 'psroff' script similar to 'nroff'. Here are the context diffs:
-
- *** /usr/local/bin/nroff Sat Feb 13 15:51:09 1993
- --- /usr/local/bin/psroff Sat Feb 13 17:45:46 1993

-
- # This shell script is intended for use with man, so warnings are
- ! # probably not wanted.
- ! exec groff -Wall $T $opts $rest
-
- The binaries on cb-iris.stanford.edu have these changes already made.
-
- Paul Walmsley <ccshag@cclabs.missouri.edu> offers the following
- advice for IRIX 5.x, which assumes that you have already followed
- David Hinds' instructions for IRIX 4.0.x:
-
- 1. Remove the link from tbl to gtbl.
-
- 2. Rename gtroff to gtroff-exe or some other suitable name. Note
- that if you name it something other than gtroff-exe, you must
- change the gtroff script below.
-
- 3. Install the gtroff and tbl scripts included below in place of the
- above two programs, and chmod them appropriately.
-
- --- cut here for tbl ---
- #!/bin/sh
- # Shoehorn gtbl into IRIX 5.2 - Shag
- # Removes the -TX from gtbl's command line - yes, I know this is a kludge
-
- rest=`echo ${1+"$@"} | sed -e 's+-TX++'`
- exec gtbl $rest
- --- cut here for gtroff --
- #!/bin/sh
- # Shoehorn gtroff into working with IRIX 5.2 - Shag
- # Translates all references for /usr/lib/tmac to /usr/local/lib/groff/tmac,
- # and disables warnings - from David Hinds' code
-
- rest=`echo ${1+"$@"} | sed -e 's+/usr/lib/tmac+/usr/local/lib/groff/tmac+'`
- exec gtroff-exe -Wall -mtty-char $rest
- --- you can stop cutting now ---
-
- It is also possible to avoid the need for these scripts by setting
- some environment variables, which are only documented in the man(1)
- manpage (q.v.) in IRIX 5.2 and later.
-
- Finally, under IRIX 5.3, you need to edit the 'eqn' and 'neqn' scripts
- (above) a bit more. Add the following line
-
- if [ ${1:-""} = - ] ; then shift ; fi
-
- just before the last "geqn" line.

-
- ------------------------------
-
- Subject: -23- Why isn't Iris Insight working properly?
- Date: 23 Mar 1996 00:00:01 EST
-
- The format for Insight's ~/.insightrc file changed in Insight 2.0. An
- ~/.insightrc left over from an older version might cause Insight to
- emit error messages or not work in various ways. Just delete the old
- ~/.insightrc and restart Insight.
-
- Insight generates PostScript which says "language level" where it
- should say "languagelevel", and thus may not print on your printer.
- Pipe the PostScript to a file, change every "language level" in the
- file to "languagelevel" and print that.
-
- Insight doesn't understand the lpr printing system. To allow Insight
- to print to an lpr printer, you must provide an lp interface to it.
- See "How can I use lpr instead of or as well as lp?" in the admin FAQ.
-
- Insight, as well as other ViewKit applications, uses the Xpm library
- (/usr/lib/libXpm.so). If you install another version of that library
- where Insight can find it, Insight may coredump. Remove or hide the
- new version of the library.
-
- Greg Ferguson's <gferg@hoop.timonium.sgi.com> list of other problems
- with Insight is at
- ftp://viz.tamu.edu/pub/sgi/software/insight-problems. Most or all
- have probably been fixed in subsequent versions of Insight and IRIX.

-
- Subject: -24- Why don't the arrow keys work in vi?
- Date: 04 May 1994 00:00:01 EST
-
- Arrow keys send more than one character, and vi can misinterpret them
- as multiple single-character commands on slow connections. Increase
- vi's patience by putting the command 'set timeout=400' (or a larger
- or smaller number to your taste) in the file ~/.exrc or the EXINIT
- environment variable. See also the ex(1) and vi(1) manpages.
-
- Or use h, j, k and l. Or jot or Emacs.
-
- Incidentally, an article in the March/April 1994 Pipeline discusses a
- variety of 'vi' tips and tricks.

-
- Subject: -25- How can I tell application X about my screen size?
- Date: 30 Mar 1996 00:00:01 EST
-
- IRIX does not have 'stty rows n' or 'stty columns n' yet; it will in
- 6.2. Until then, use 'setenv LINES n' and 'setenv COLUMNS n'.

-
- Subject: -26- Why does ksh lock up if one's home directory is NFS-
- mounted?
- Date: 15 Oct 1995 00:00:01 EST
-
- ksh(1) uses a single ~/.sh_history file for all of a given user's ksh
- processes, so must be able to lock that file. Locking is robust for
- local files but not over NFS. Install patch 547 (or its successor) to
- fix some known NFS bugs and be sure lockd is 'chkconfig'ed on and
- rpc.lockd and rpc.statd are actually running. If all else fails, set
- the HISTFILE environment variable to a file on a local disk.

-
- Subject: -27- Why can't I 'talk' to Suns?
- Date: 16 Mar 1994 00:00:01 EST
-
- SGI, and most Unix vendors, use the 4.3BSD talk protocol, while Sun
- still uses the 4.2BSD talk protocol. The fault is Sun's, not SGI's.
- Look in ftp://thor.ece.uc.edu/pub/sun-faq/ for Sun-compatible versions
- of 'new talk' (ntalk.tar.Z) and 'ytalk', which speaks both old and new
- 'talk' (ytalk-3.0.1.tar.gz).
-
- You could also run 'ytalk' on your SGI. Get it from
- ftp://ftp.uu.net/usenet/comp.sources.unix/volume27/ytalk-3.0/.

-
- Subject: -28- How can I change what the keys on my keyboard do?
- Date: 04 May 1994 00:00:01 EST
-
- Use xmodmap(1). The manpage describes how to swap control and caps-
- lock, which is the most common use. xwsh(1G) and tcsh(1) also have
- key-binding facilities, described in their manpages; consider these
- if you want to change key meanings only in 'xwsh' windows or only in
- 'tcsh'.

- Subject: -29- Why is 'jot' so slow on a remote display in IRIX 5.2?
- Date: 03 Jun 1995 00:00:01 EST
-
- It's a bug. A fixed version is in ftp://ftp.sgi.com/graphics/jot/.
- The bug is fixed in IRIX 5.3.
-
- ------------------------------
-
- Subject: -30- Why does 'man -k' repeat itself in IRIX 5.2?
- Date: 03 Jun 1995 00:00:01 EST
-
- 'man -k' looks for two whatis databases, the default
- (/usr/share/catman/whatis) and one in a directory specified by the
- environment variable LANG. If LANG is set but empty, the paths come
- out the same and you see the same database twice. Fix the problem by
- doing 'unsetenv LANG' or 'setenv'ing it to something sensible.
- This is not an issue in IRIX 5.3.
-
- This can also happen if the old Irix 4.0.x database is left behind
- after upgrading to Irix 5.2. Fix the problem by removing
- /usr/catman/whatis.

- Subject: -31- Netscape 1.1S (the custom SGI version) says it can't
- find 'soundplayer'. What should I do?
- Date: 23 Sep 1995 00:00:01 EST
-
- 'soundplayer' is a new tool which has not yet become part of IRIX
- proper. Bryan James <bryanj@spiff.esd.sgi.com> describes several ways
- to deal with its absence:
-
- - Get Webforce (an extra-cost product) or Digital Media Tools 5.5
- (free from
- http://www.sgi.com/Products/Evaluation/dmedia/dmedia.html), both of
- which include soundplayer. Both require IRIX 5.3.
-
- - 'sfplay' is part of standard IRIX and handles almost all of the same
- audio formats as does 'sfplay'. Edit the file
- /usr/local/lib/netscape/mailcap and replace every instance of the
- word "soundplayer" with "sfplay".
-
- 'sfplay' does NOT handle mpeg audio bitstreams (.mp2) like those
- from the Internet Underground Music Archive site. Get 'maplay', an
- MPEG audio file player, from
- ftp://ftp.cs.tu-berlin.de/incoming/maplay1_2/; you can get the C++
- source code (maplay1_2.tar.Z) and compile it yourself or just get
- the IRIX binary (maplay_indigo.Z). (See also Doug Cook's audio apps
- list, referenced in the misc FAQ.) After you've set up 'maplay',
- edit /usr/local/lib/netscape/mailcap, find the line beginning with
- "audio/x-mpeg" and replace the word "soundplayer" with "maplay" on
- that line only.

-
- Subject: -32- Netscape emits "X Error"s. What should I do?
- Date: 07 Sep 1996 00:00:01 EST
-
- It's a bug, fixed by patch 1095. You may also be able to work around
- the problem by removing conflicting X resource files or setting the
- resource "Netscape*useEnhancedFSB: False".
-
- ------------------------------
-
- Subject: -33- Netscape complains about a conflicting 'Netscape' file.
- What should I do?
- Date: 09 Dec 1995 00:00:01 EST
-
- The file in question, probably /usr/lib/X11/app-defaults/Netscape, is
- the X resources (app-defaults) file from another version of Netscape.
- No version of Netscape actually needs that file, so remove it and all
- your versions of Netscape can coexist.
-
- If you can't, or if you want a customized app-defaults file for each
- version of Netscape, use a script like this:
-
- #!/bin/sh
- # Set NS to the directory containing the Netscape distribution
- NS=/usr/local/lib/netscape-2.0b3
- XUSERFILESEARCHPATH=$NS/%N.ad:$XUSERFILESEARCHPATH
- export XUSERFILESEARCHPATH
- exec $NS/netscape $*

- Date: 07 Sep 1996 00:00:01 EST

- (/var/X11/xdm/Xsession.dt) in IRIX 6.2. To stop it, do 'chkconfig
- firsttimeprograms off'.

-
- Subject: -36- What are the correct versions of the Irix Development
- Option (IDO) and Fortran for current versions of IRIX?
- Date: 06 Feb 1997 00:00:01 EST
-
- If you're using IRIX 4.0.x, you should be using IDO 4.1.1. It
- includes C 3.10.1 and the 3.12 back-end (the part of the compiler
- which actually produces the executable; 3.12 is the number you see
- when you use the 'file' command on an executable). The previous
- version was badly buggy; upgrade ASAP.
-
- IRIX 5.2 needs IDO 5.2, which includes C 3.18. Executables produced by
- the IRIX 5.x back-end don't show a version number with 'file', although
- this information can be obtained via 'odump -V'.
-
- Each version of IDO has a corresponding version of Fortran, and they
- MUST be used together. IDO 4.1.1 needs Fortran 3.5.1 and IDO 5.2 needs
- Fortran 4.0.1. This is true for other languages as well, but only
- Fortran has confused enough people to have its version numbers here.
-
- Ping Huang <pshuang@sgi.com> adds:
-
- IRIX 5.3 needs IDO 5.3, IRIX 6.0 needs IDO 6.0, and IRIX 6.1 needs
- IDO 6.1; that's pretty easy.
-
- After that, IDO version numbers are no longer tightly coupled to the
- IRIX version number. The first IDO for IRIX 6.2 was IDO 6.2, but
- then IDO 7.0 and IDO 7.0.1 came out for IRIX 6.2 as well. And IDO
- 7.1 comes in three different flavors: IDO 7.1 for IRIX 6.2, IDO 7.1
- for IRIX 6.3, and IDO 6.1 for IRIX 6.4.
-
- If you use IRIX 6.2, use IDO 7.1 for IRIX 6.2. If you use IRIX 6.3
- or 6.4, the appropriate flavor of IDO 7.1 is your only choice (for now).
-
- ------------------------------
-
- Subject: -37- Why can't I compile my non-ANSI C program?
- Date: 11 Jun 1995 00:00:01 EST
-
- SGI's C compiler is ANSI C by default in IRIX 4 and later. Use the
- '-cckr' option to compile K&R (traditional) C. You can do this most
- easily by setting the environment variable SGI_CC to "-cckr" or by
- editing the application's Makefile, often by adding "-cckr" to the
- CFLAGS variable.
-
- A related problem is that Makefiles generated by 'imake' most often
- use 'cc -cckr -prototypes'; missing or incorrect prototypes usually
- just generate pages of warnings but may cause an unrecoverable
- error. You can often work around this by removing "-prototypes" from
- the line where it appears in the Makefile (not the Imakefile).
-
- ------------------------------
-
- Subject: -38- Why doesn't application X understand NIS (Yellow Pages)?
- Date: 11 Feb 1996 00:00:01 EST
-
- Under IRIX 4.0.x, programs which access files served by NIS must be
- linked with -lsun. The functions in libc.a which deal with these files
- are not NIS-aware; the NIS versions are in libsun.a. Using libsun.a
- usually means adding '-lsun' to the variable LIBS or LDFLAGS in one's
- Makefile. If '-lc' or '-lc_s' (libc_s.a is the shared version of
- libc.a) is given explicitly, '-lsun' must precede it.
-
- Under IRIX 5.x, libc.so is NIS-aware and -lsun is unnecessary.
- However, linking with -lnsl and/or -lsocket will confuse libc.so and
- NIS access won't work. Either remove -lnsl and/or -lsocket or put an
- explicit -lc *before* them in the link line.
-
- ------------------------------
-
- Subject: -39- Where's 'edge' in IRIX 5.x? What can I use instead?
- Date: 03 Sep 1995 00:00:01 EST
-
- SGI does not include edge with IRIX 5.x. When asked for substitutes,
- SGI will direct you to their CASEVision debugger, which costs extra.
-
- An oft-mentioned free graphical debugger is 'xdbx'; you can find the
- original source in ftp://ftp.x.org/R5contrib/, a patch to make it work
- on IRIX 4.0.x in
- ftp://viz.tamu.edu/pub/sgi/software/debug/xdbx.sgi.patch and patched
- versions for IRIX 4.0.x and 5.x in
- ftp://swedishchef.lerc.nasa.gov/programs/X/. An 'inst'-installable
- binary for IRIX 5.x only is in ftp://ftp.sgi.com/sgi/xdbx/.
-
- If you have 'gdb', you can try 'tgdb' and 'tgdb_wish', which may be
- FTPed from ftp://sunsite.unc.edu/pub/Linux/devel/debuggers/ and
- ftp://ftp.aud.alcatel.com/tcl/code/ respectively.

-
- Subject: -40- How can I generate IRIX 4.0.x-compatible executables
- under IRIX 5.x?
- Date: 06 Apr 1996 00:00:01 EST
-
- Strictly speaking, you can't. Many things changed in IRIX 5.x. You
- can, however generate executables in COFF (IRIX 4.0.x) format instead
- of ELF (IRIX 5.x) format, and these will often work on IRIX 4.0.x if
- they don't use complex things like multiprocessing. The manual and
- release notes describe how, and here's a summary:
-
- 1) Make sure you've installed all of the appropriate irix4
- compatibility subsystems. These include irix4_eoe, irix4_dev,
- irix4_c and others for Motif, Inventor, etc.
-
- 2) setenv SGI_IRIX4 1
-
- 3) If your source uses explicit paths to headers, libraries, etc.,
- change them to point to the irix4 versions.
-
- 4) Use cc or make or whatever as you normally would.
-
- You can't do this in IRIX 6.2., which doesn't support COFF at all.
-
- ------------------------------
-
- Subject: -41- How can I convert IRIX 4.0.x executables to IRIX 5.x?
- Date: 04 Nov 1994 00:00:01 EST
-
- Sez Jay McCauley <mccauley@sgi.com>: IRIX does not and cannot have a
- coff2elf (actually, it's 'cof2elf') converter. The COFF (actually,
- ECOFF) to ELF transition was also the transition to the use of
- Expanded Fundamental Types (EFT), an SVR4-ism. EFT enlarges a number
- of basic data types, finally casting off the last vestiges of the
- PDP-11. So, structures built in an EFT world would have their
- members at different offsets than they would in a pre-EFT (e.g. IRIX
- 4.x) world. The operating system uses the fact that an executable is
- in ELF to trigger the use of EFT-based strucures for input and
- output. So, even if you had a program like coff2elf, the resulting
- transformed executable would not operate correctly for almost any
- interesting case. Trivial programs that don't have any system calls
- which pass in structures or get structures back from the OS could
- theoretically work, but these fall into the "uninteresting" class.
-
- Note that the cof2elf(1) program referred to by the elf(1) manpage in
- IRIX 5.2 does not exist. The elf(1) manpage is wrong.
-

- Subject: -42- Why are some non-shared libraries missing in IRIX 5.x?
- Date: 02 Jan 1995 00:00:01 EST
-
- - Some of the non-shared libraries which do come with IRIX 5.x are
- installed by default and some are not. The shared library you want
- may be in one of the "speclibs" subsystems,
- e.g. dev.sw.irix_speclibs, which contains /usr/lib/nonshared/crt1.o,
- a very popular item among those compiling nonshared.
-
- - IRIX 5.x does not have non-shared versions of some libraries,
- notably libX11.a. Nonshared libraries are provided if 1) they are
- required by the MIPS ABI (Application Binary Interface), a
- binary-compatibility standard, 2) they are needed to compile
- benchmarks (these are the libraries in the "speclibs" subsystems) or
- 3) SGI hasn't gotten around to providing a shared library.
-
- So, why do you want that nonshared library?
-
- - If you just want to compile something whose link statement
- explicitly specifies a particular nonshared library, substitute the
- shared version (e.g. libX11.so.1 instead of libX11.a).
-
- - If you really need a nonshared application, and you can't find all
- the nonshared libraries you need, you're out of luck.

- Subject: -43- Where are the audio, CD and DAT libraries in IRIX 5.2?
- Date: 18 Mar 1995 00:00:01 EST
-
- In IRIX 5.2, they (and the associated headers, sample code, etc.)
- moved to the extra-cost Digital Media Development option. In IRIX
- 5.3, they moved back to IDO.

-
- Subject: -44- Why can't my networking application resolve hostnames in
- IRIX 5.x?
- Date: 14 May 1994 00:00:01 EST
-
- The resolv.conf file, which tells IRIX how to resolve hostnames, is
- in /usr/etc in IRIX 4.0.x but /etc in IRIX 5.x. Applications compiled
- under IRIX 4.0.x and moved to a 5.x system will not be able to find
- it. The easiest fix is to do 'ln -s /etc/resolv.conf /usr/etc', and
- the best fix is to recompile. See 'man 4 resolv.conf'.

-
- Subject: -45- Can I use dynamic shared objects in IRIX?
- Date: 07 May 1993 00:00:01 EST
-
- IRIX 5.x supports SVR4-style dynamic shared objects. IRIX 4.0.x does
- not, but Jack Jansen <jack@cwi.nl> has written a package to do it
- anyway. Get ftp://ftp.cwi.nl/pub/dl-1.3.tar.Z.
-
- ------------------------------
-
- Subject: -46- How can I tell which shared objects my executable uses?
- Date: 05 Nov 1995 00:00:01 EST
-
- To see static dependencies (the names of libraries specified at
- compile time), use 'odump -Lv' for COFF format executables (under IRIX
- 4.0.x, or 5.x using the irix4 compatibility stuff) and 'odump -Dl' or
- 'elfdump -Dl' for ELF format executables (IRIX 5.x only). (Both are in
- the dev.cmplrs_sw.util subsystem.)
-
- To see dynamic dependencies (the full paths to libraries determined at
- runtime, after environment variables are taken into account, which is
- what SunOS' 'ldd' tells you), use rld.debug and turn on rld tracing
- with _RLD_ARGS. See the rld(1) manpage.

-
- Subject: -47- Why does malloc() never return NULL?
- Date: 05 Jul 1994 00:00:01 EST
-
- Virtual memory is effectively infinitely large in IRIX 4.0.x, and it
- can be configured to be so in IRIX 5.x. malloc() never returns NULL
- because requests are always granted. The admin FAQ gives further
- background, and tells how to configure your system to limit virtual
- memory to physical memory and physical swap space.
-
- ------------------------------
-
- Subject: -48- What is the difference between libc's malloc() and
- libmalloc's malloc()?
- Date: 22 Oct 1995 00:00:01 EST
-
- Under versions of IRIX prior to 5.x, malloc(3X) -- the malloc in
- libmalloc -- was preferable to the libc malloc, or malloc(3C).
- However, in IRIX 5.x and above, the libc malloc is faster and is
- probably preferable.

-
- Subject: -49- What prototypes are missing in IRIX 4.0.x and 5.x?
- Date: 03 Sep 1995 00:00:01 EST
-
- Kevin Russo <russo@rudedog.nrl.navy.mil> has compiled lists, which you
- can FTP from
- ftp://viz.tamu.edu/pub/sgi/software/programming/missing-protos.shar.
-

-
- Subject: -50- Where are the regcmp and regex functions?
- Date: 13 Nov 1994 00:00:01 EST
-
- In the libPW.a (IRIX 4.0.x) or libgen.a (IRIX 5.x) library. Add
- '-lPW' or '-lgen' to your linking command.
-
- ------------------------------
-
- Subject: -51- Why does make(1) complain about syntax errors that I
- can't find?
- Date: 26 May 1994 00:00:01 EST
-
- Two possibilities:
-
- - SGI's make sends shell commands to your shell (specified in the
- SHELL environment variable), while every other make in the world
- uses /bin/sh by default. Put the line "SHELL=/bin/sh" at the top of
- a Makefile to tell SGI's make to use /bin/sh.
-
- - Dependency lines in your Makefile may begin with spaces. Some
- 'make's accept spaces; SGI's requires tabs.
-
- ------------------------------
-
- Subject: -52- What's wrong with strip(1)?
- Date: 06 Apr 1996 00:00:01 EST
-
- In IRIX 5.2 and 5.3, strip(1) fails to remove all of the debugging
- information that it could. This isn't a big problem; it just wastes
- a bit of disk space. Patches 247 and 248 fix that bug.
-
- Patch 410 to IRIX 5.3 includes a new loader (ld32), the output of
- which strip mangles horribly. Patch 1068 and IRIX 6.2 include a strip
- which can strip ld32 binaries, but which does not follow symlinks.
-
- In IRIX 6.0 and 6.0.1, 'strip *' strips the first executable correctly
- and corrupts the rest. Work around the bug by stripping only one file
- at a time.

-
- Subject: -53- Why does my floating point signal processing routine,
- when given certain inputs, run incredibly slowly and
- consume all of the CPU in _system_ or _interrupt_ time ?
- Date: 03 Sep 1995 22:28:13 PDT
-
- You may be experiencing an undesirable "floating point underflow"
- behavior of the floating point unit on R3k's and beyond. You'll need
- to add a workaround to your code and, on some machines, install a
- patch as well. A thorough writeup by Chris Pirazzi of SGI
- <cpirazzi@cp.esd.sgi.com> is at
- ftp://viz.tamu.edu/pub/sgi/software/programming/fp-underflow.

-
- Subject: -54- Why don't IRIX 5.3 executables run on IRIX 6.0.1?
- Date: 04 Aug 1995 00:00:01 EST
-
- IRIX 6.0.1 was based on IRIX 5.2. IRIX 6.1 is based on IRIX 5.3
- and runs IRIX 5.3 binaries accordingly.
-
- ------------------------------
-
- Subject: -55- Why don't COFF executables run on IRIX 6.1 or 6.2?
- Date: 15 Jun 1996 00:00:01 EST
-
- IRIX 6.1 has kernel support for COFF executables, but does not have at
- least some of the shared libraries. If you copy the needed shared
- libraries from an IRIX 6.0.1 (or perhaps 5.3) system to your IRIX 6.1
- system your COFF executable should work.
-
- IRIX 6.2 does not have kernel support for COFF, so you will have to
- recompile your COFF binaries. The IRIX 6.2 installation procedure will
- warn you about COFF binaries, although only on local disks; be sure to
- check machines yourself which provide binaries to IRIX 6.2 machines
- via NFS. You can find COFF binaries yourself with something like
- 'find / -print | xargs file | grep COFF', or use the script
- ftp://ftp.sgi.com/support/Pipeline/coffcheck.tar.Z. See also "The End
- of COFF Support" in the Jan/Feb 1996 Pipeline.

-
- Subject: -56- What object file formats does IRIX 6.2 support?
- Date: 20 Dec 1996 00:00:01 EST
-
- Bruce Karsh <karsh@audio.esd.sgi.com> and Ping Huang <pshuang@sgi.com>
- write: IRIX 6.2 supports
-
- 6 processors: R4000, R4400, R4600, R5000, R8000, R10000
- 3 ABIs: -32, -n32, -64
- 4 instruction sets: mips1, mips2, mips3, mips4
-
- Irix 6.2 will not support R3000 (or earlier) processors.
-
- Instruction sets:
-
- mips1: The old 32 bit R3000 instruction set. It's mostly for
- compatibility. New code probably should not use it.
- Available on all 6 processors.
-
- mips2: Adds more floating point registers Adds some improvements
- to the floating point instructions. mips2 code may be a
- bit smaller than mips3 code.
- Available on all 6 processors.
-
- mips3: General purpose registers are 64 bits wide. Some new
- instructions are added to load, store, and manipulate 64
- bit wide quantities.
- Available on all 6 processors.
-
- mips4: Adds some supercomputing-style instructions.
- Available on the R5000, R8000, and R10000.
-
- The mips1 and mips2 instruction sets both are available only on the
- -32 ABI. The mips3 and mips4 instruction sets both are available
- on either the -n32 or -64 ABI, but not on the -32 ABI.
-
- You may mix -mips1 and -mips2 objects together to make a -mips2
- executable. You may mix -mips3 and -mips4 objects together to make
- a -mips4 executable. No other mixing of instruction sets is
- allowed.
-
- ABIs:
-
- -32: Supports the 32 bit instruction sets. This is just what we
- are all used to from 5.3.
- Available on all 6 processors.
-
- -n32: Supports the 64 bit instruction sets, but not pointers and
- longs all remain 32 bits long. (long longs are 64 bits
- wide). The -n32 ABI is source code compatible with -32.
- Available on all 6 processors.
-
- -64 Supports 64 bit instruction sets and 64 bit pointers.
- longs and pointers are all 64 bits wide. Great for apps
- which need a LARGE address space. The -64 ABI is not
- source code compatible with -n32 and -32 since in -64 longs
- and pointers are now 64 bit quantities. This means that
- casts of ints to/from pointers will not work in most cases
- and the layout of structs will be different.
- Available on the R8000, R10000, and the IP19 (R4400)
- processors only, due to OS restrictions.
- ( -64 requires a large kernel).
-
- Summary:
-
- Format Function Processors
- ------ -------- ----------
- -32 -mips1 old, 32 bit, mostly for compatibility ALL
- -32 -mips2 above plus more fp regs, faster fp ALL
- -n32 -mips3 64 bit regs, 32 bit pointers ALL
- -n32 -mips4 above plus supercomputer instructions R5/8/10000
- -64 -mips3 64 bit regs, 64 bit pointers IP19 R4400 &
- R8/10000
- -64 -mips4 above plus supercomputer instructions R8/10000
-
- The compiler can produce executables in all supported formats on all
- supported processors, although not all formats will *execute* on all
- processors. The old 4.x object file format, COFF, will no longer be
- supported. Only the newer format, ELF, will be supported.
-
- ftp://viz.tamu.edu/pub/sgi/software/programming/sgi_opt_level.c
- determines programmatically the highest optimization level that can
- be performed on the current CPU.

-
- Subject: -57- What are GP-relative and GOT overflows, and how can I

- Date: 21 Nov 1995 00:00:01 EST
-
- Read the dso(5) and gp_overflow(5) manpages. If you don't have the
- latter (it exists only in very recent compiler releases), see
- ftp://viz.tamu.edu/pub/sgi/software/programming/gp-overflow-errors.

-
- Subject: -58- Why can't Perl open a socket on my SGI?
- Date: 21 Dec 1995 00:00:01 EST
-
- You're handing socket() the wrong constants (address family or socket
- type). These used to be standard across almost all Unixes (including
- IRIX 4.x and earlier), so were often hardcoded in Perl scripts, but
- changed in System V release 4 Unixes (including IRIX 5.x and later),
- so the hardcoded values became wrong. At least one routine included
- with Perl (syslog.pl) makes this error, and does not work on IRIX 5.x.
-
- Read /usr/include/sys/socket.h to see what the values are on your
- system. To get them into your Perl program in a nice way, either
- 'require socket.ph' or (under Perl 5) 'use Socket'.
-
- Entry 4.21 of the Perl FAQ (http://www.perl.com/perl/faq/Q4.21.html)
- will back us up on this.
-
- Incidentally, patch 596 fixes (among other things) a separate problem
- with the socket interface.

- Subject: -59- PORTING
- Date: 10 Dec 1993 00:00:01 EST
-
- This section discusses problems with porting software from other
- systems to SGIs. Be sure to look through the previous section and the
- programming part of the graphics FAQ too.
-
- ------------------------------
-
- Subject: -60- How can I make the 'install' program work like BSD
- 'install'?
- Date: 22 Nov 1994 00:00:01 EST
-
- The BSD and System V versions of the 'install' command are
- incompatible; the BSD version is most often used by Makefiles. IRIX
- provides both the System V version (/etc/install) and the BSD version
- (/usr/bin/X11/bsdinst.sh in IRIX 4.0.x, and /usr/bin/X11/bsdinst in
- IRIX 5.x). SGI's 'imake' defines INSTALL as /usr/bin/X11/bsdinst,
- and the Install* rules use that definition, so Imakefile-generated
- Makefiles will use the BSD version.
-
- Michael Joosten <joost@ori.cadlab.de> points out that you can also use
- GNU install (available from any GNU archive, e.g.
- ftp://prep.ai.mit.edu/pub/gnu/), which emulates the BSD version.
- Unlike /usr/bin/X11/bsdinst, it has a manpage. It also may be better
- debugged; SGI's version reportedly mishandles '-o' and installs
- multiple files into a single directory.
-
- ------------------------------
-
- Subject: -61- Where's 'ranlib'?
- Date: 16 Sep 1993 00:00:01 EST
-
- IRIX doesn't need it. Read the description of the 's' option in the
- ar(1) manpage. When the Makefile for a program you're porting wants
- ranlib, delete the ranlib command, substitute 'true' or put a little
- shell script in your PATH to fake it.
-
- ------------------------------
-
- Subject: -62- What do I need to do to build gcc/g++?
- Date: 4 Nov 1998 00:00:01 EST
-
- Presuming you have the IDO (Iris Development Option) installed,
- recent versions of gcc build reliably on IRIX without much
- difficulty. Just read the INSTALL document and follow the
- directions. A few hints:
-
- - Don't. Several people have already, and they'll let you have a
- copy. Even if you must do it yourself, you can bootstrap from
- someone else's binary. Furthermore, their distribution may include
- notes on how they did it, if they didn't think it was obvious. See
- "Where can I get software already compiled for SGIs?" above.
-
- - Don't forget to install the dev.cmplrs_hdr.internal (IRIX 4.0.x),
- dev.hdr.lib (IRIX 5.x, 6.0.x, 6.1), or eoe.hdr.lib (IRIX 6.2+)
- subsystem, which contains needed headers and is not installed by
- default.
-
- - READ THE RELEASE NOTES! gcc (and gas, etc.) are updated too
- frequently for this FAQ to document every quirk of every release.
- The release notes often describe quirks that have not yet been
- fixed.
-
- The following advice applies if you do not have the IDO installed:
-
- If you're running any release of IRIX previous to 6.2, you will be
- unable to build or use gcc, since you will be missing critical
- header files and runtime libraries. Of course if you buy IDO you'll
- get SGI's compiler anyway; this is comp.sys.sgi.*'s most popular
- Catch-22.
-
- IRIX 6.2 (or later) comes with a full set of headers. Before anything
- else - make sure you have all the SGI headers. They are not installed
- by default, but are on the 6.2 CD in the subsystem eoe.hdr.lib.
-
- As of IRIX 6.5, support for gcc is much improved and includes the new
- ABIs (n32, 64). The SGI backend (including an assembler and linker
- supporting the n32 and 64 ABIs) plus all the bits and pieces needed
- for gcc (headers, libraries, runtime startup files, etc.) are included
- free with any IRIX 6.5 distribution on the 2 CDs titled "Development
- Foundation" and "Development Libraries" (in other words you don't need
- to have the SGI Developer's Option in order to use gcc.)
- In recent SGI releases, the SGI assembler and linker are in the
- subsystem compiler_dev.sw.base.
-
- Precompiled versions of gcc and g++ that were well-tested on 6.5
- and are known to work on IRIX 6.2 and up can be found in
- <http://reality.sgi.com/ariel/freeware> and will be available shortly
- on the SGI freeware site <http://freeware.sgi.com/>.
