Using xerces-c on AIX
Hi,
I have built an app using xerces-c as a shared lib on Linux. I'm now
trying to get it running on AIX 5.1.
Issue 1:
The binary download of xerces-c for AIX appears to have static libs
(.a), but no shared libs (.so). Is this deliberate, and if so, what is
the reason?
Issue 2:
When I try to compile from source using gcc/g++ 2.9, I get a link
problem. I can compile other c/c++ apps successfully on this machine.
The runConfigure script seems ok:
./runConfigure -p aix -cgcc -xg++ -nfileonly -rpthread
And the compile seems ok.
But I get this link error:
gmake[1]: Entering directory `/home/simon/xerces-c-src_2_5_0/obj'

It looks rather like libstdc++ is not being found or something.
Thanks in advance,

Thanks for the very useful pointers above, David.
The fact that code compiled with gcc/g++ is incompatible with the xlC
linker rather makes the -c and -x options to the runConfigure script
irrelevant, does it not?
Anyway, this is now really a GCC-on-AIX problem rather than a xerces-c
problem, so I won't take up any more bandwidth here.
But just in case someone does have any last suggestions, here's what I'm
getting after following David's suggestion as best I can. If anyone here
has managed to compile any dynamic shared library on AIX using gcc
tools, I would appreciate your comments, even if it's just to say that
yes it is possible.
--------------
I've modified Makefile.incl, but can't find the right combo of options
to create a dynamic shared library on AIX using GNU "ld".
The "-shared" option to ld is, according to the man pages, only
available on "ELF, XCOFF and SunOS platforms". This matches nicely with
the error message I'm getting:
g++ -DAIX -shared -fPIC -Wl,-soname,libxerces-c25.so -o
/home/simon/xerces-c-src_2_5_0/lib/libxerces-c25.0.so ...
collect2: libxerces-c25.so: cannot open as COFF file
The output of gld --help does state that "aixcoff-rs6000" is supported
(the target server is AIX5.1 on rs6000). But I've tried using "--oformat
aixcoff-rs6000" without success. Experiments continue....
[NB: the ld version installed is: GNU ld 2.9-aix43-010414]
Cheers, and thanks for all the help.
Simon

Yes. If you need to use a different compiler I suggest you download the
source and recompile.
For you link problem, the build for AIX assumes you are using xlC. So when
you specify a compiler of gcc/g++ it still uses xlC for the link. You
would need to override the Makefile.incl in /src/xercesc to test the
compiler and then point to the appropriate libraries for g++ and invoke
something other than makeC++SharedLib_r.

Hmm..it appears that AIX uses the suffix '.a' for dynamic shared libs.
How nice :-(. Well that issue's solved.
However if I compile code with either g++ or xlC v5, then link against
the xerces-c libs in the prebuilt download, I get link errors. None of
the xerces-c APIs can be found.
Is it possible that g++ and xlC v5 use different name-mangling
algorithms from xlC v6, which the binary xerces download was built with?

I'd still *really* appreciate any suggestions on this.
