Could this be a 32bit/64bit architecture/compiler problem? Your Perl seems to be a 64bit Perl (maybe, or just using 64bit ints, I don't know AIX well):

aix-thread-multi-64int
[download]

... but you're trying to use/link to 32bit libraries:

/opt/tuxedo/11.1_32/lib/libtux.a
[download]

If you don't resolve this otherwise, maybe showing the full output of perl -V can help us find if there is something wonky in between what the dynamic loader wants and what Perl wants and what your OS installation has.

Hi Anonymous Monk and Corion,


When I get into work I will post more details on the progress I've made, thanks to some insight generated by questions/suggestions made by a co-worker.

I should have mentioned in my original post the details about 'multi-64int'. It is generally true on AIX one cannot inter-mix 32 and 64 bit object code. However, despite the 'multi-64int' being in the output, our Perl is indeed 32-bit object code. In fact, a special copy of Perl was built by our development group to avoid the 64-bit copy installed system-wide (hence the /path/to/ references).

After reading my posting, a co-worker suggested the -G linker option may be hiding the problem, because it implies -berok (i.e. link errors are okay and should be ignored). I should add -Wl,-bernotok (i.e. link errors are *not* okay) and try again.

This lead to the discovery that Tuxedo.so, as generated, has no references to libraries. Thus the runtime-linker has nothing to work with. We then noted an if/else block in Makefile.PL called out for different link options on Windows vs Unix and the comment in the Unix section mentioned 'tested on Solaris'. Ah, so the author may not have had the joy of working on AIX ;)

We then adapted the link options for Windows to AIX, mostly by discarding a bunch of Windows specific libraries and repeated our efforts until we could link a Tuxedo.so when -Wl,-bernotok was on the command line.

Thus we're past the link issue. Now on to some issues with the ubbconfig file, not passing syntax checks.

Regards,
-Randy

Hi PerlMonks,

I have managed to resolve my linking issues and have generated a patch (diff -u) for the module. This works for our environment (GCC on AIX). Alas, I could not resolve one problem. PERLSVR core dumps upon initialization. It appears to be right at the point where perl_alloc() is called. Without PERLSVR one cannot create a Perl-based Tuxedo server. Fortunately all I need is a Tuxedo client.

I addressed a number of other issues that came up in our environment. These may not impact others, but have nonetheless been expressed in the following diff output.
