Main / Experiences / How to Tell AIX Compiler Version

I recently had to determine the version of the AIX compiler running on a few machines at work. Unfortunately, there doesn't seem to be a good way to do that. The best way seems to be to check the installed software list. I got that idea from this usenet post. In particular, I used lslpp -L | grep vac.C. I also found that strings `which cc` | grep "C for AIX" worked too, and may give a more accurate number than the installed software list.
