I've been trying to build boost on an amd64 machine under Debian Linux but it hangs trying to compile part of the wave library. Is it possible to skip building the wave library as a temporary work around (I am not familiar with jam)? I'm using the deb source package (from 1.33.0) from the unstable Debian distribution: http://packages.debian.org/unstable/source/boost I am building on the stable distribution (i.e. trying to create a back port because of the broken timed mutexes in 1.32). The build gets to: "g++" -c -Wall -ftemplate-depth-255 -D_REENTRANT -g -O0 -fno-inline -pthread -I"bin/boost/libs/wave/build" -I"/home/users/russell/cvs/debPackages/boost/boost_1_33_0" -I "/home/users/russell/cvs/debPackages/boost/boost_1_33_0" -o "bin/boost/libs/wave/build/libboost_wave.a/gcc/debug/threading-multi/instantiate_cpp_literalgrs.o" "/home/users/russell/cvs/debPackages/boost/boost_1_33_0/libs/wave/build/../src/instantiate_cpp_literalgrs.cpp" "/usr/bin/objcopy" --set-section-flags .debug_str=contents,debug "bin/boost/libs/wave/build/libboost_wave.a/gcc/debug/threading-multi/instantiate_cpp_literalgrs.o" at which point it hangs (top shows cc1plus using 99.9% CPU). Please let me know if I can supply more info to help debug this problem. Russell Kliese
