The config.guess file only support AIX 4 and 5 while searching for the CPU type. Instead of finding a POWER6 based CPU, it falls back on rs6000. If you go to line 555 in config.guess you can see : *:AIX:*:[45]) and if you turn this line into *:AIX:*:[456]) as in the config.guess for 3.1.0.rc1, it works fine also and I'm able to build a shared library ;-) Could you provide me an Official statement on the changes I have to do in the xerces 3.0.1 version I have to make it build on my setup ? I now have anther question. Why is the Optimizer turned off during a xerces build ? Is it expected ? From the test I've done, there a performance gain of a factor 3 when using -O2 to build. I just ran into an issue with the xlC 10.1 optimiser which produce a core dump (SIGSEGV). Crash occurs in the DOMDocumentImpl.hpp:384 *pspe = spe = (DOMStringPoolEntry *)allocate(sizeToAllocate); To fix the issue I used the following compiler option : -qalias=noansi (it has to do with optimizer behavior with pointer aliasing) Thanks for your help Best Regards, Gauthier Cannot build shared library from xerces-c 3.0.1 on AIX6.1 with xlC V10.1 Key: XERCESC-1904 URL: https://issues.apache.org/jira/browse/XERCESC-1904 Project: Xerces-C++ Issue Type: Bug Components: Build Affects Versions: 3.0.1 Environment: OS : AIX 6.1 TL3 SP1 Compiler: IBM XL C/C++ Enterprise Edition for AIX, V10.1 Reporter: Gauthier Helin Priority: Blocker Attachments: config.log, config.log_3.1.0 Hello, I cannot build the xerces 3.0.1 shared library on AIX 6.1 with xlC 10.1.

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.
