Hi I have some problem to compile boost 1.32 with comeau. I use como 4.33 + gcc 3.3.5 on Linux Ubuntu. During the comilation I have some error : ...found 4271 targets... ...updating 489 targets... como-C++-action bin/boost/libs/test/build/libboost_prg_exec_monitor.so/como/debug/execution_monitor.o Comeau C/C++ 4.3.3 (Oct 24 2003 16:00:23) for RedHat_LINUX_INTEL_ELF Copyright 1988-2003 Comeau Computing.

If you have some idea Best regards
