Grr, now that http://aixpdslib.seas.ucla.edu is offline, I am struggling to find a binary version of gcc for PASE for V5R3 (which is actually AIX 5.2)
Course, the IBM website http://www-03.ibm.com/systems/p/os/aix/linux/index.html "AIX Toolbox for Linux Applications" would seem to be a place to get things, including gcc.
But to get stuff from the toolbox, you have to install the RPM package manager. Sure, great. Oh, and RPM uses the "installp" utility.
And, of course, from IBM "OS/400 PASE does not support the AIX smit or installp utilities typically used to install applications on an AIX system"
The alternative AIX binary site, http://www.bullfreeware.com/, has gcc, albeit older versions. But they are .exe files which I have been unable to open.
Ack! Chicken - egg - time paradox - hair pulling - gnashing of teeth.
I am hoping that I have missed something easy here and throw myself on the mercy of the newsgroup for any and all suggestions.
