Hi again, so, I've now switched to trying to build boost using KCC (4.0f9, I need both KCC and gcc versions). And that opened up a whole new slew of cans of worms... 1. the <address-model>64 doesn't seem to do anything here, the proper option (-q64) is not used. I can turn it on with "<cxxflags>-q64 <linkflags>-q64 <arflags>-q64" and that seems to work. 2. when building the thread library (and possibly others), the option to turn on threading (--thread_safe) is not used, resulting in error messages: "/scratch/scratchdirs/patrik/boost_1_32_0/boost/config/requires_threads.hpp", line 86: catastrophic error: #error directive: "Compiler threading support is not turned on. Please consult your compiler's documentation for the appropriate options to use" # error "Compiler threading support is not turned on. Please consult your compiler's documentation for the appropriate options to use" If I manually turn it on using "<cxxflags>--thread_safe <linkflags>--thread_safe <arflags>--thread_safe", I can compile it, but... 3.

There are numerous compiler errors and warnings preventing many libraries from building. I've attached the full build log to this email. cheers, /Patrik
