I haven't gotten a response to a problem I posted yesterday. Could
someone give me a hint how to go about debugging it myself? I've got a
little time now, and I'm pretty desperate to get this resolved.

The problem appears to be in, or at least related to, DynaLoader.pm.

Thanks.

perl5.002beta1, patches a-f installed. Attempting to install
Sybperl-2.0.

Not really. It's an o/s limitation.

Run ldd on the perl binary and on CTlib.so.

Delete from the Makefile ld command any references to libraries (other
than libc) which are listed for perl.

Then again I may be wrong. Either way talk to the author of the module.

Hmm. I'll guess you might have two different versions of
a libsybase.a and libsybase.so around. (I have no idea what the
actual names are, of course.) Try
ldd /home/technoids/bin/perl5
and make sure it's pulling in all the libraries you *think* it should be
pulling in, and that the 'ld' command that created CTlib.so used the
same libraries.

That's my guess where to start. I've never used Sybase stuff.

Good luck.

Yup, I'd say you've got a problem!

If your MakeMaker says something about use of %att being depreciated
then fetch a very recent one from a CPAN archive (it'll still give
the warning but won't muck up the Makefile).

Other than that I can't think of much else. CC'd to Michael Peppler.

Tim.

Thanks, I'll give it a try.

Here's the output--not exactly what I'd expect. Obviously I've got a
problem somewhere. Any suggestions what it might be, or how I can
track it down?

BTW, thanks very much for responding.

CTlib> ldd /home/technoids/bin/perl5

I forgot to mention that I had previously installed perl5.001n with
and Sybperl-2.0 extension w/o any problems at all. That's what has made
me think the problem has something to do with perl5.002beta1. Of
course, it's possible that something in my environment has been
changed unbeknownst to me...
