Hi - I'm trying to build boost on an AIX box using GCC, and am having pthread issues. In particular: ------------------------------------------------------------------------ $ uname -a AIX dev-app-a00 2 5 00089FFC4C00 unknown unknown AIX $ gcc -v Reading specs from /usr/local/lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3.3/specs Configured with: ../gcc-3.3.3/configure --disable-nls Thread model: aix gcc version 3.3.3 $ bjam -v Boost.Jam Version 3.1.10. OS=AIX.

Any insight would be useful. I've been googling around a bit, but haven't found much for this particular issue... Thanks. Dan
