Subject: Think C & 68k cross compiling

Sorry, this is a repost, cause the title wasn't accurate....

Hello,
Can anyone help me with info about compiling for non Mac 68K based
systems using ThinkC 5.0 or a C++ compiler? I own ThinkC 5.0 and I have
to write some code for a 68332 based robot.  (68332 is a superset of
68K with some 020 instructions).

My (many) questions are these :

Is there a utility for stripping CODE resources of JUMP tables, and
locating code at a specific address (say for moving code to a ROM)?

Is there a way to ensure that no system (OS, ROM or otherwise) code is
called when Think C compiles it?

What exactly does A5 point to when a application is first launched ?

Could someone explain (in more detail than the manual) the format of
CCOD resources and how I could use them to produce code for a non Mac
target.

And finally, is there a C++ (or some object extended C compiler) I can
use with an option for non Mac targets to save mucking around. (And has
anyone ported gnu g++ to a MAC (not AUX) ? I know GNU aren't real fond
of Apple but if its been done that would be fab.)

I am planning to use the Mac to download the code to the target, so I
may write an app which loads its own resources, strips its jump table
and spits itself out the serial port. If this is useful to others, I'll
make it PD.

All that said (asked) I am doing all this for my undergrad thesis and
there are only 8 weeks left so I really need urgent info. Please help.


Many thanks,


A. James Boswell.

Under THINK C, compile as a code resource with custom headers-- this
should make pure code, with none of the header stuff.  I'm fairly sure
this will even be loadable to ROM.  THINK C applications are not, as they
use installation code to fix some references.  Don't use any globals--
you will have to handle them yourself.

>Is there a way to ensure that no system (OS, ROM or otherwise) code is

Don't make any trap calls, and don't include any libraries.  Also,
don't use floating point.  I'm 99% sure that will do it.

If you want to use MPW, see Apple tech Note 240-- it has all sorts of
info on the pitfalls of using MPW to make standalone code.

Make a single segment code resource with the custom header checkbox set.

It is ok to use globals, but any entry points you will need to to a lea
a4,main to setup the register to point to the globals.  The globals are
mixed in with the code so you might have a problem if the hardware wants
to write protect the code.  You can't take the address of a variable
inside a data declation (eg a staticly initialized array containing
pointers to routines) the compiler will give an error.  Don't load
mactraps or mactraps2.  It is ok to use some of the library routines,
add the .c files one at a time as needed for things like memcpy, ctype.

Yes, I modified the code in Programmer's Key which checks for the ROM
code of the Mac Portable, and changed it to check for the ROM code of
the PB170.  You could do the same with the PB140 code.

Some information is in the IM, developer CDs have the System 6 WDEF,
and TN 298 talks about the System 7 Window colorization.

Also, MacApp has the HyperCard floating window WDEF sources so you could
use those for whatever you want. I guess old MacTutor articles also
talks about WDEF hacking.

Someone told me that there is a file type BPPL which denotes a background
application (such as the old Backgrounder).  However, when I use ResEdit to
change an app from APPL to BPPL, the program still runs perfectly, even in
the foreground.

So what the heck is a BPPL program, anyway?  Is there any difference
between an APPL and a BPPL?  I can't seem to find any documentation on this
phenomenon anywhere.


Thanks in advance.

It's an Apple provided tool which checks parameters sent in and out from

Why not just use BlockMove?  Unless you're going to be doing scads
and scads of little tiny moves, BlockMove will do a fine job, without
compatibility problems.  And you could even get the trap address and
avoid trap overhead, if you want to.

Has the block come through a dumb Ethernet card, an A-ROSE Ethernet card,
Token Ring or LocalTalk? Even EtherTalk Phase 1 and EtherTalk Phase 2
are misaligned by one byte (you can have IP-in-MacIP-in-EtherTalk).
You can't tell - don't take the risk.

> Why not just use BlockMove?

Even something as trivially simple as:

    char *p, *q;
    while (n--)
        *(q++) = *(p++);

is faster than BlockMove for n < 50 - even as a subroutine!
Therefore checking for word-alignment and doing long-copies in a
subroutine is going to be faster for n < 200 or so. Using proper
unrolled assembly code is always going to be faster (because that's
what BlockMove() is probably doing).

Your mileage may vary.

Yes. A friend did a study of this and came up with a break-even point of about
32 to 34 bytes for a byte-copy loop, about 50 bytes for an unrolled byte-copy
loop. And by grabbing the address of BlockMove (to avoid trap dispatch
overhead) things got faster still.

BlockMove does something very close to this. Break out MacNosy to see for

BlockMove is a trap (0xA02E) while the construct above executes directly
in memory. Any code causing a dispatch will always execute slower
than pure RAM resident constructs.

First, in the future please try to insert hard carriage returns so your post
will wrap onto multiple lines, for those of us using news readers which require
this.

What you want to do is called palette animation; on an indexed device (1-8
bits, 2-256 colors) it allows you to instantly change an index from one color
to another, changing all the instances of that color on the screen.  It's
a little too complex to describe well in this message, so I'll refer you to
Inside Macintosh; IM V,pg 156, or IM VI, pg 20-10 should get you started;

On Location index files?  I'm assuming, of course, that CSMP is essentially
a large community conversation where all participants are aware that their
comments are broadcast, and so moving the notes to a different medium wouldn't
require copyright releases from everyone who even said "This is a test...".
CD-ROM production prices are reasonable, CD-ROM players are becoming plentiful
(now that I have one :-), and the overhead might be low enough for it to fly.

  What do people think?  Would a semi-annual CD-ROM be worth ten or fifteen
bucks or would it already be too stale?

I think this would be an excellent idea, but rather than just a compendium of
C.S.M.P. as it appeared on USENET, why not have the articles grouped by
subject (ala C.S.M.P. Digest) ?

On the other hand, there is already a company that is planning to issue CD-ROMs
containing _all_ USENET news.  It's called NetNews/CD, and they are supposed
to start shipping CD-ROMs in ISO9660 format (with a Mac reader) sometime this
month.

Personally, I'd probably prefer one that had _only_ C.S.M.P., with probably
some of the other Mac-specific newsgroups (e.g., c.s.m.system, c.s.m.hardware,
comp.protocols.appletalk, etc.).

If you think that you can pay for all your production costs selling a CD-ROM
for ten or fifteen bucks, I will be in line to buy one... :-)

Sterling Software has been shipping USENET News on CD-ROM since the first of
the year in Sun UFS format.  We are in the final stages of preparation for
producing an ISO 9660 format version.  (News doesn't fit real well into the
ISO 9660 format...)  The Mac reader is a problem in that the only version with
sources we have been able to aquire is NewsWatcher. It has limitations in
that it uses the list manager for displaying newsgroups. Newswatcher can't
handle the 1800 to 2500 newsgroups which are on the CD-ROMs each issue... :-(
We are trying to work around it but it has not been as easy a process as it
initially appeared.  (It never is...) Because of that we do not expect to be
shipping a Mac reader until May.  If someone has other Mac readers for which
they can supply sources please contact me and maybe we can speed up the
availability of the Mac readers.

We are planning on producing specialized yearly series CD-ROMs.  The Mac
groups were one we had considered.  If you are interested in seeing us do
that please send email to [e-mail] and let us know.

More information on the service and its directions can be found by sending
email to [e-mail] or via anonymous ftp from ftp.uu.net in the

Another issue would be a form of intelligent editing of the contents, so
we would have a better format for browsing and searching. It's a huge task,
though.

Subject: LISP and DrawString questions
From: [e-mail]
Date: 6 Apr 92 12:35:23 -0400
Organization: Wittenberg University

I asked both of these questions before but I never received any answers because
the newsfeed here went down for 5 days and we missed all those messages.

First:  I'm looking for a public domain version of LISP.  Does anybody know of
one (if so, where can I get hold of it)?

Second: I want to draw white text on a black background and everything I
display using DrawString just appears as black (which is no good since that is
the same color as the background!).  I've tried changing the PenPat, but that
doesn't work.

Thanks!

Is this on the FAQ list?  Eric Sink posted a list of free/shareware
compilers a while back;  I think that belongs in the FAQ.

I don't know of a LISP, but there's a decent Scheme at
sumex-aim.stanford.edu.

There are two schools of thought, I believe.  The first method is to
change the PenPat and make sure you're using TextMode(srcCopy).  The
default mode is srcOr, and or'ing white won't do a thing.  The second is
to draw in TextFace(outline), again with srcCopy.  There really isn't
any reason to do the second (unless you're sloppy and are likely to
forget to change the PenPat back to something reasonable), but it's a
handy trick to know when you're using stupid graphics programs that
won't let you do text white-on-black.

There's a nice LISP called "SIOD" short for Scheme In One Defun. Check
for it with archie.

Text drawing uses CopyBits; you'd have to use a TextMode ( patXor ) or
TextMode ( patBic )

I made an error... using patXxx where srcXxx is appropriate is a
good way of making things invisible on SEs and earlier machines.

Check comp.lang.lisp now and then for their FAQ, it should have a list of
known PD LISP systems running under MacOS, including ftp addresses.

As for PD stuff, there are few (any?) Common Lisps which are free that I know
of. Our Common Lisp implementation, MCL, costs 495$US, and it's a bargain
compared with what you get, CLOS, Mac libraries, most of the stuff you need
in the LISP world. Similar Windows packages are usually 5000$US upwards
(development environment).

What I know it's one of the few *Apple internal* tools, so we can't
release it. I guess I could ask if we could send it out as an alpha
tool.

Subject: Silly question about determining DirIDs
Date: 8 Apr 92 23:18:21 GMT
Organization: Xerox PARC, Palo Alto, CA

This seems like it should be obvious, so I'm afraid that I'm asking a
stupid question, but how do you find out the DirID of a directory?

In particular, I have an alias record to a directory which I've extracted
from a database.  I then resolve the alias into an FSSpec, and then want
to create new files in the named directory.  I assumed that the best way
to do this was to call FSMakeFSSpec for the VRefNum,DirID,and new file name,
followed by an FSpCreate.  However, I can't seem to figure out how to
get the DirID given an FSSpec.

I tried (in C++ MacApp code where fAlias is an AliasHandle):

    OSErr err;
    FSSpec dirspec;
    Boolean changed;
    err = ResolveAlias(NULL,fAlias,dirspec,changed);
    FailOSErr(err); // To simplify the example...

    HParamBlockRec info;
    CStr255 name = dirspec.name;
    info.fileParam.ioCompletion = NULL;
    info.fileParam.ioNamePtr = name;
    info.fileParam.ioVRefNum = dirspec.vRefNum;
    info.fileParam.ioFDirIndex = 0;
    info.fileParam.ioDirID = dirspec.parID;
    info.fileParam.ioFVersNum = 0; // Just for grins
    err = PBHGetFInfo(&info,FALSE);
    FailOSErr(err);
    fDirID = info.fileParam.ioDirID;

but fDirID is always the DirID of the aliases parent, not of the named
directory.

Just for completeness, in case the problem is actually with the
alias itself, it was created with:

    OSErr err;
    FSSpec dirspec;
    err = FSMakeFSSpec(NULL,NULL,"Oracle:ClipBin:",&dirspec);
    FailOSErr(err);

    // Get an alias record to the bin's directory
    AliasHandle alias;
    err = NewAlias(NULL,dirspec,alias);
    FailOSErr(err);
    FailNIL(alias);            // Not sure if this is necessary
    fAlias = alias;

What am I doing wrong?  I'm more interested in what's the right way to
accomplish my higher level goal (of storing alias records to directories
in some database which I can later use to specify where I should create
data files (in particular QuickTime movies)).

Thanks.

You can't copy strings this way in C...

Three weeks ago I posted these, and here we go again:

    pb . dirInfo . ioVRefNum = fss -> vRefNum ;

    FailOSErr ( PBGetCatInfo ( & pb , 0 ) ) ;

    ASSERT ( pb . hFileInfo . ioFlAttrib & 0x10 ) ;
    return pb . dirInfo . ioDrDirID ;
}


OSErr
GetDirName ( short vol , long dir , unsigned char * name )
{
    CInfoPBRec pb ;

    BlockClear ( & pb , sizeof ( pb ) ) ;
    pb . hFileInfo . ioFDirIndex = -1 ;
    pb . hFileInfo . ioDirID = dir ;

Sorry, Jon, but while you can't copy strings in C that way, you can copy
them in C++ using the CStr255 class (which is defined in some MacApp headers).

I think that they will eventually be part of the normal MPW C++ distribution.
They certainly make *my* life easier.
