Has anyone out there (surely someone must have ;) done a successful build of 4.3.0 under AIX 6.1? I'm having one heck of a time getting things to work properly, most likely because I'm trying to use an AIX 5.3-built compiler and (of course) IBM had to go and massively change things in their latest OS version. So...Any hints/tips/tricks on this? I can configure cleanly, but things get severely confused with libiberty and several different headers during the make process (mostly in /usr/include, which since my current GCC was IBM-supplied is why I think I'm running afoul of OS related changes). The source compiler is GCC 4.1.0, built for AIX 5.3 Thanks! Rob Rob Sherry Systems Administrator Alaska Housing Finance Corp.
