- Lynx PROBLEMS file.
-
- Ideally you would never have to read this, but inevitably problems
- do arise. As implementation and installation problems become known
- they will be outlined in this file.
-
- Control-Z on Unix can cause aberrant behavior. If you encounter
- problems, use -restrictions=suspend to disable it, and only '!'
- for escapes to shell (on VMS control-Z is unconditional 'Q'uit,
- with no attempt to suspend the Lynx process only temporarily).
- Control-Z on Unix often works better with slang.
-
- Screen resizing can be a bit funny. If you resize the screen,
- documents that have been cached will be out of whack. Any further
- documents will look fine. You can reload documents to the current
- window size with CTRL-R
-
- On a Sun system, the message:
- "Alert!: Unable to connect to remote host"
- will be displayed every time an attempt is made to access a host
- other than localhost if Lynx has been built without the resolv
- library and needed it, or with it and shouldn't have been.
- Unfortunately, there's no way to check in the Makefile whether
- -lresolv should be included in the LIBS="" list. What's necessary
- depends on how that Sun is configured. To get the build right for
- your SUN 3 or 4 OS, if you didn't have RESOLVLIB defined in the
- Makefile define it and build Lynx again, or vice versa. Also, if
- you have upgraded to the bind-8.1 or later library, you should try
- changing -lresolv to -lbind.
-
- The Sun `shelltool' and `cmdtool' terminals are stupid by default.
- In order to get bold text to appear differently than inverse video,
- the user should put this line in ~/.Xdefaults:
-
- Term*boldStyle: Offset_X
-
- From the `shelltool' man page, it seems that an analogous line
- in ~/.defaults
-
- /Tty/Bold_style "Offset_X"
-
- ought to work just as well, but you may not get the desired
- behavior until you modify your .Xdefaults file (and run `xrdb
- ~/.Xdefaults'). Note also that there are other supported values
- for the boldStyle resource/Bold_style default, all of which begin
- with "Offset_". (helpful hint from kevin@traffic.den.mmc.com)
-
- Directory browsing has been implemented for VMS, but there are no
- plans to port additional DIRED support, because Lynx must handle files
- as streams, and this precludes "serious" Directory/File Management on
- VMS. Use a jumps file link to CSwing (sources or executables are
- available from ftp://narnia.memst.edu), or define CSWING_PATH in
- userdefs.h or lynx.cfg to invoke CSwing via the DIRED_MENU command.
-
- If one switches between K)eypad "Numbers act as arrows" versus "Links
- are numbered" in the 'o'ptions menu when the current document is a
- DIRED menu in which links have been tagged, the tagging can be trashed
- (so don't switch at such times 8-).
-
- When "Links are numbered" is on, if a line is split on an anchor (to
- obey right margin restrictions), and there is no space in the bolded
- string such that the entire "[#]string" must be moved down, the "[#]"
- becomes bolded, instead on only "string".
-
- The Mosaic v2.5 hostlist uses HTML similar to that of Lynx's bookmark
- file, but with </UL></HTML> at the bottom, such that it is not fully
- compatible with Lynx's file. If you try to use the Mosaic file as if
- it were a Lynx bookmark file, the </UL></HTML> will not be taken into
- account and new links will be added below rather than above those end
- tags. Instead, add a link to the Mosaic file in your Lynx file, and
- to the Lynx file in your Mosaic file, so that you can access both files
- with both clients.
-
- SOCKSification and the -socks switch have not yet been integrated with
- the slang library support.
-
- There is an apparently broken version of select() in libcurses.a
- of HP/UX 10.10. It also breaks tn3270, ncftp, emacs, and xemacs.
- Using:
- LIBS="-lc -lcurses -ltermcap \
- ^^^
- (i.e, adding -lc *before* the -lcurses) in the snake3 and snake3-slang
- targets of the top level Makefile yields a useable image, but with
- inappropriate video attributes on the Lynx displays (reverse video and
- underscores on everything). Using "-lc -lHcurses" instead fixes the
- ^^^^^^^^^
- video attributes but then the arrow keys are messed up. - Donald S.
- Teiser (dsteis01@homer.louisville.edu)
- NOTE: If HP fixes the problem or you come up with a better workaround,
- notify the lynx-dev@sig.net list.
- Updated NOTE (1996-09-02): A patch reportedly is available from HP to
- fix the select() problem, so that "-lc" is no longer needed, but
- the curses glitch is not yet fixed, and you should still include
- "-lHcurses".
- Updated NOTE (1997-02-03): The problems reportedly are fixed with
- patches PHCO_8086 and PHCO_8947 from HP.
- Updated NOTE (1997-12-15): PHCO_8086 & PHCO_8947 are very old and are
- no longer available. The current patch to install if running
- under HP-UX 10.20 is PHCO_11342.
-
- Lynx juggles variable abilities of curses packages or emulations to
- display bolding and underlining simultaneously. This may fail if
- Lynx thinks that your terminal, in connection with the curses package,
- supports a capability which the terminal hardware or emulation does not
- in fact support. Setting the right TERM environment variable, tweaking
- terminfo or termcap files, or compiling with a newer version of ncurses
- or slang may solve problems with missing highlighting or strange
- characters appearing on the screen. Also, for a mono terminal, make sure
- that there is no "show color (&) : ON" on the Options screen.
-
- The Wyse 50 and older TeleVideo terminals, among others, are
- "magic cookie" terminals. This means that display attributes like
- reverse, blink, underline, etc. work in a bizarre way that makes them
- difficult to program. You may see extra spaces scattered around your
- screen (separating different sorts of highlight); or sections of the
- screen may be unexpectedly highlighted.
- There is a workaround which works by restricting the terminal to a
- single standout attribute (e.g. normal and reverse, but no others).
- Implementing the workaround is specific to your curses implementation.
- Most versions of curses use one of two terminal databases, called
- "termcap" and "terminfo". Updating these databases is system-specific.
- New databases should be available from the vendor or other sources.
- For the Wyse 50, try
- <URL: http://www.wyse.com/text/custserv/faq/wy50faq.htm>;
- extract the "wy50" (NOT "wy50-mc") entry and use that in place of the
- existing one. See `terminfo', `infocmp', `tic' etc. man pages if
- necessary.
- Alternatively, compiling Lynx with the slang library may avoid problems
- with theses terminals.
-
- On VMS, Lynx, and other TCP-IP software, have been experiencing chronic
- problems of incompatibilities between DECC and MultiNet headers whenever
- new versions of either DECC or MultiNet are released. The Lynx build
- procedure for VMS and a maze of spaghetti #ifdef-ing in tcp.h of the
- libwww-FM had previously been successful in dealing with this problem
- across all versions of MultiNet and of DECC, VAXC, and Pat Rankin's
- VMS port of GNUC, but are now not 100% successful. If you get compiler
- messages about "struct timeval timeout" having no linkage, add that
- declaration immediately below the inclusion of ioctl.h for MultiNet in
- tcp.h (by deleting the "#ifdef NOT_DEFINED" and "#endif /* NOT_DEFINED */"
- lines):
- [...]
- #include "multinet_root:[multinet.include.sys]ioctl.h"
- struct timeval {
- long tv_sec; /* seconds since Jan. 1, 1970 */
- long tv_usec; /* microseconds */
- };
- [...]
- If you get compiler warnings about incompatible multinet_foo()
- declarations, delete those where indicated in tcp.h. For the most
- current versions of MultiNet, you can modify tcp.h to use the DECC
- socket and related headers.
-
- On VMS, the ftp function does not work with SOCKETSHR 0.9D and NETLIB
- 2 (NETLIB 1 may work). This is because the functions getsockname()
- and getpeername() within SOCKETSHR make incorrect calls to the NETLIB
- functions. This results in zeroes being returned for part of the local
- IP address. Since ftp sends this IP address to the remote end, the
- remote server ends up sending a file back to a non-existent address.
- Andy Harper (A.HARPER@kcl.ac.uk) has fixed these problems in the
- SOCKETSHR 0.9D sources and offers the fixes as:
- http://alder.cc.kcl.ac.uk/fileserv/zip/socketshr_src_09d-2.zip
- ftp://ftp2.kcl.ac.uk/zip/socketshr_src_09d-2.zip
