Hello, I'm trying to build boost using VC++ 7.1 against STLport 5.0 rc2. The very first library that is built is boost_date_time.dll and the compiler chokes on greg_month.cpp. The full bjam output is at the end of the message. Some background info, that may be useful: - I can successfully build boost without STLport using this this command: bjam "-sTOOLS=vc-7_1" "-sBUILD=debug release <runtime-link>dynamic <threading>multi" --prefix=..\boost --builddir=..\boost-obj install - when using STLport I build using: bjam "-sTOOLS=vc-7_1-stlport" "-sSTLPORT_PATH=..\STLport\stlport" "-sBUILD=debug release <runtime-link>dynamic <threading>multi" --prefix=..\boost --builddir=..\boost-obj install - if I let the building process continue, it builds about 60% of all libraries - I need to use STLport5 because it supports VC++ 7.1 out of the box - I've tried building CVS/HEAD version of boost as well as the latest released version 1.32 So, has anybody tried building this combination? Thanks in advance. Here is the full output.
