Hi, is anyone out there who has successfully built and used omniORB3.x/omniORBpy1.x on AIX4.3 with xlC 5.0x and python2.0? If so, are there any patches, that have to be applied to the omniORB (or python) sources? Python and omniORB seem to work fine, but whenever we try to use omniORBpy, we end up in core dumps that result from calls to pthread_mutex_lock. Can anyone give us a hint? Thanx Jan
