I downloaded boost 1.37.0, unzipped and ran $ ./configure $ make install It dies reliably with: ------------------ ./tools/jam/src/bin.linuxx86/bjam -sICU_PATH=/usr --user-config=user-config.jam --prefix=/home/timm --exec-prefix=/home/timm --libdir=/home/timm/lib --includedir=/home/timm/include install error: at /home/timm/downloads/boost_1_37_0/tools/build/v2/build/project.jam:846 error: duplicate initialization of gcc with the following parameters: error: version = 4.3.2 error: previous initialization at /home/timm/downloads/boost_1_37_0/tools/build/v2/build/project.jam:846 Not all Boost libraries built properly. ------------------- This is on a relatively unmodified Ubuntu Intrepid linux install. I could only find one other mention of this problem on the web and it was a mailing list post with no answer, so I'm apparently doing something quite unusually wrong. FWIW, the reason I'm building from source rather than using a package is that the Ubuntu packages don't seem to provide a binary lib for MPI - am I missing something here? They provide header files, so it seems eccentric not to provide a package with libs. Tim
