I wonder whether anyone could speak about exactly what versions of the supporting operating systems we should expect to work, particularly specifics about compilation requirements and instructions. I've been trying to build hwloc-1.2 on some of our old AIX systems (5.2, 5.3, 6.1), without success in all cases. I've tried both the default configuration (which selected gcc, but could not complete the configure step) and using CC=/usr/vac/bin/cc (configure did complete but the make soon found fault with lines in lstopo-text.c). I've appended the usual compressed tarballs, but if I've missed some extant, more detailed instructions (which I also didn't find searching the mailing list archives), I'd appreciate being told where to go. :-)
