Since AIX does not export symbols unless either it has to (if needed for direct linkage to a shared object) or you REALLY want it to (either by -bexpall or by providing an exports list), these symbols don't resolve. So it either crashes (if compiled without -brtl) or complains about unresolved references. Is there a Libtool-standard way to make the executable export all of its symbols?The standard is to add libtool flag -export-dynamic to executable LDFLAGS but may be libtool is not ported to you linker.For GNU linker: ./libtool --config | grep export_dynamic export_dynamic_flag_spec="\${wl}--export-dynamic" Roumen
Since Daniel's e-mail address return mails - reason: User unknown so I quote response.
You're right: On AIX this flag is blank. I'm also scratching my head

Daniel please find attached file bootstrap.sh.gz with sample code and build based on autotools. The sample is strip down of C++ version. Please could you adapt to you host environment and post result to list so that people with experience on AIX to help you. Also it is wort to try libtool version 1.2.26 where AIX support is improved or may be to check 2.1b since it will be rool up soon.
