problem linking 1.3.3

[Emmanuel Dreyfus <p9...@criens.u-psud.fr>]

Hi!

I've troubles with dynamic linking both on 1.3.3 and previous versions
from the CVS:

$ make test
PERL_DL_NONLAZY=1 /usr/pkg/bin/perl -Iblib/arch -Iblib/lib
-I/usr/pkg/lib/perl5/5.6.0/powerpc-netbsd -I/usr/pkg/lib/perl5/5.6.0 -e
'use Test::Harness qw(&runtests $verbose); $verbose=0; runtests @ARGV;'
t/*.t
t/DOMCreate.........Can't load 'blib/arch/auto/XML/Xerces/Xerces.so' for
module XML::Xerces:
/usr/pkgsrc/textproc/xerces-p/work/XML-Xerces-1.3.3/blib/arch/auto/XML/X
erces/Xerces.so: Undefined PLT symbol "__eh_alloc" (reloc type = 21,
symnum = 660) at /usr/pkg/lib/perl5/5.6.0/powerpc-netbsd/DynaLoader.pm
line 200.
 at blib/lib/XML/Xerces.pm line 7

__eh_alloc is in libgcc.a, I would have expected it to be in the perl
executable. Anyone has an idea why it does not link?

$ gcc -v 
Using builtin specs.
gcc version egcs-2.91.66 19990314 (egcs-1.1.2 release)

Well, the missing symbol, __eh_alloc, can be found only in libgcc.
libgcc is a static library only, if I try to link with -lgcc, I will get
other link errors (non supported relocation), because libgcc is not PIC
code.

Hi Emmanuel,

Thanks for giving it a whorl on NetBSD!! I hope we can get it working.

I'm surprised by this. Searching the WWW I found:

This is for pretty old versions of gcc, but I wonder if something
similar is happening. What version of gcc are you using?

If that isn't the issue, I check would be the link line for Xerces.so,
whether it included all the necessary libraries.

In the Makefile.PL call to WriteMakefile, you may need to add some
NetBSD system dependancies, in one of the following lines:

  'CCFLAGS'     => '-D_REENTRANT -DDEBIAN -DHAS_BOOL -D$(SWIG_VERSION)',
  'INC'         => "-I. -INew_classes_perl $INCLUDES",
  'LIBS'        => "$LIBS -lxerces-c1_3 -lpthread",

I might have access to a BSD machine at the CS dept, and I can try
building it there. 

HTH,
jas.
