The exact command line was
bjam --toolset=msvc-8.0 --without-python cxxflags=/wd4251 stage
and the exact output was
D:/Projects/Boost/boost_1_34_0/tools/build/v2/build\property.jam:282: in validate1 from module property error: Invalid property '<cxxflags>': No value specified for feature 'cxxflags'. D:/Projects/Boost/boost_1_34_0/tools/build/v2/build\property.jam:290: in property.validate from module property D:/Projects/Boost/boost_1_34_0/tools/build/v2/build\build-request.jam:185: in convert-command-line-element from module build-request D:/Projects/Boost/boost_1_34_0/tools/build/v2/build\build-request.jam:143: in build-request.from-command-line from module build-request D:/Projects/Boost/boost_1_34_0/tools/build/v2\build-system.jam:265: in load from module build-system D:\Projects\Boost\boost_1_34_0\tools\build\v2/kernel\modules.jam:261: in import from module modules D:\Projects\Boost\boost_1_34_0\tools\build\v2/kernel/bootstrap.jam:132: in boost-build from module D:\Projects\Boost\boost_1_34_0\boost-build.jam:9: in module scope from module
I saw the same thing yesterday when trying to use 'cxxflags'. Here's the version output from bjam which I downloaded from Sourceforge at the same time I got the 1.34.0 source code: Boost.Build V2 (Milestone 11) Boost.Jam 03.1.14 The file date is 4/30/2007 which co-incides with the package date on Sourceforge. -Chris
