Very Computer

I have a number of interactive graphics applications that were
programmed for IrisGL from 1990 to 1993. I do not have the resources at
present to port them to OpenGL and these programs are still very
useful. One application is in Fortran; all the others in C. They are
currently running on my SGI Indigo^2 running IRIX 5.3. I had no
problems in going from IRIX 4.something to IRIX 5.0. However, I cannot
find the appropriate libraries for linking when I compile in IRIX 6.2.
The 5.3 binaries DO NOT RUN on 6.2

I use: -lgl_s -lm -lfm_s
under 5.3 without problems. Using 6.2, I get error messages that gl_s
and fm_s do not exist. I cannot find equivalent libraries.

Please note that I am not a professional programmer although I have
some programming skills. Any help would be greatly appreciated.

Change them to "-lgl -lm -lfm" and recompile the whole program.

The reason the "5.3" binaries (were they really built on 5.3?) do
not run on 6.2 is most likely because they are "coff"
executables, instead of "ELF" format.

Say your program is called foo, are you getting an error similar to:

    Cannot execute binary file
    foo - Exec format error

To find out what type of format your binary is, use file:
    file foo

and you'll get something like below...

foo: MIPSEB COFF executable (paged) not stripped - version 2.10
foo: ELF 32-bit MSB dynamic executable (not stripped) MIPS - version 1

If your binary is COFF, then compiling your app on 6.2 is the
correct thing to do.  But, that 6.2 binary will probably only
work on the 6.2 machines you have.  In otherwords, 5.3 is not
forwards compatible with 6.2 (so you cannot run a 6.2 binary
on 5.3), but 6.2 is backwords compatible with 5.3 (and older)
ELF binaries (so if your binary was in ELF format it should
work on 6.2, if not please let us know).

So, keep using the old version on the 5.3 machines, and use
the new version on 6.2 and future OS/machines.

Hope this helps,
