Pthread compile problem

[Philip Edward Lewis]

I'm using gcc (dl-ed from Bull) to compile a program:
****
gcc -o fftosql fftosql.o $II_SYSTEM/ingres/lib/libingres.a -lm -lc -lc_r -mthreads -bnoquiet -bloadmap
ld: 0711-317 ERROR: Undefined symbol: pthread_mutexattr_default
****
cc return similar:
****
/usr/vac/bin/cc -o fftosql fftosql.o -lm -lc_r -lc -lpthreads $II_SYSTEM/ingres/lib/libingres.a
ld: 0711-317 ERROR: Undefined symbol: pthread_mutexattr_default
****

I'm running AIX 4.3.3 ML11
i have bos.rte.libpthreads 4.3.3.80

Any idea about for what i should be looking?

Those functions don't even exist on AIX.

They worked (are working) on 4.2.1.

This is one of the reasons we still have 4.2.1 boxes around.

Take a look in the VAC 6.0 compiler documentation about the different
invocations of the compiler driver (cc, cc_r7 , cc_r4...)

And /etc/vac.cfg.

AFAIK they set some macros for compatibility with DCE threads.
Not sure, just an idea...

That's a draft 7 symbol. The default on current levels of AIX
is draft 10. The draft 7 module in libpthreads is load-only,
meaning that you're not able to link against it.

That said, I think there's a strip option in 4.3.3 that allows you
to set/unset the LOADONLY bit (dump -ov /usr/lib/libpthreads.a and look
at shr.o). Try -e/-E. I know this works in 5.1. Then use your
modified libpthreads for linking.

Or port the code to draft 10.

The version of strip from bos.rte.bind_cmds:4.3.3.77 has '-e/-E' ...

This is good to know: I was looking for the option to turn LOADONLY
on in the 'ld' (because I need to relink some LOADONLY modules, and
*leave* them LOADONLY), but didn't find it there. Looking in 'strip'
didn't occur to me. I ended up with a perl script that simply pokes
the right value into the executable.

Cheers,
