[xml] Solaris: relocation error when linking libxml2 with zlib

[Ralf <ralfml alfray com>]

Hi!

Summary: Has anyone succeded in compiling libxml2 with zlib support on 
Solaris?

Details:
I'm trying to compile libxml2 with zlib support on Solaris (SunOS 5.9 
Generic_112234-05 i86pc i386 i86pc) and I get a weird "relocation" error 
from the linker. The problem did not exist before when I was not 
activating zlib support.
By "activating zlib support", I mean adding --with-zlib=/some/path to 
./configure. I do not install zlib in the system, I just compile it 
manually and then reference the folder that contains lib/libz.a and 
include/z*.h

I've updated all the sources to zlib 1.2.1 and libxml2 2.6.7.
zlib compiles just fine and zlib's example.c runs with no problem. I 
also have libpng linked with it and my app uses zlib to read its files, 
so zlib works as far as I can tell.

When compiling libxml2, I get this kind of output (everything compiled 
just fine; I collapsed the many redundant symbol dumps to save some 
bandwidth):

make[3]: *** [libxml2.la] Error 1

The build process then proceeds on performaing a make install of 
include/libxml2 then a make install of . which leads yet another link of 
libxml2.la with the exact same symptoms, so I skipped that part too.

So here my solaris knownledge stops. Any help appreciated. My guess is 
that the problem is more with the user than with libxml2.
