Downloaded, extracted, and built with g++ 4.5.1, Intel icpc 10.1.20081024, icpc 11.1.20100806, and icpc 12.1.20101006 on x86_64 Ubuntu Lucid. All but Intel icpc 10.1 build successfully. On that icpc 10.1 build I see several errors like
intel-linux.compile.c++ bin.v2/libs/python/build/intel-linux/release/link-static/threading-multi/object/function_doc_signature.o ./boost/cstdint.hpp(472): catastrophic error: #error directive: defaults not correct; you must hand modify boost/cstdint.hpp # error defaults not correct; you must hand modify boost/cstdint.hpp
compilation aborted for libs/python/src/object/function_doc_signature.cpp (code 4)
which I can neither confirm/deny are specific to my environment as icpc 10.1 doesn't appear at http://www.boost.org/development/tests/release/developer/summary.html. I do not know if this is a regression relative to earlier versions. - Rhys
