Boris Kolpackov commented on XERCESC-1904:
------------------------------------------
To fix 3.0.1 you will need to install a fairly recent versions of autotools
(automake, autoconf, and libtool) and run the reconf script in the root
directory of the Xerces-C++ distribution (you can do it on a machine other than
your AIX box).
Regarding optimization, I am not sure what is the default debug/optimize
setting for XLC in autotools. I know for g++ it is -g -O2. But you can always
override this on the configure command line:
./configure CFLAGS=-O2 CXXFLAGS=-O2
I tend to think that the core dump with optimization enabled is a bug in XLC.

> Hello,
> I cannot build the xerces 3.0.1 shared library on AIX 6.1 with xlC 10.1. It
> always produce the static library even if I specify --enable-shared=yes.
> I tried may different ./configure and gmake options without any success.
> here is some output of the ./configure which shows that it thinks that the
> linker does not support shared libs :
> checking if xlc_r supports -c -o file.o... yes
> checking whether the xlc_r linker (/usr/bin/ld) supports shared libraries...
> no
> checking dynamic linker characteristics... no
> checking how to hardcode library paths into programs... unsupported
> checking whether stripping libraries is possible... no
> checking if libtool supports shared libraries... no
> checking whether to build shared libraries... no
> checking whether to build static libraries... yes
> configure: creating libtool
> appending configuration tag "CXX" to libtool
> checking whether the xlC_r linker (/usr/bin/ld) supports shared libraries...
> no
> checking for xlC_r option to produce PIC...
> checking if xlC_r static flag works... yes
> checking if xlC_r supports -c -o file.o... yes
> checking whether the xlC_r linker (/usr/bin/ld) supports shared libraries...
> no
> checking dynamic linker characteristics... no
> (cached) (cached) checking how to hardcode library paths into programs...
> unsupported
> appending configuration tag "F77" to libtool
> checking whether xlc_r and cc understand -c and -o together... yes
> the command line used was :
> ./configure --prefix=$PREFIX CXX=xlC_r CC=xlc_r --enable-shared=yes
> gmake libxerces_c_la_LDFLAGS=-qmkshrobj
> This was working fine on AIX 5.3 with xlC 7
> Thanks a lot for any help.
