[boost] Problem to use boost

Hi, this is what I've done: compiled with commandline of bjam "-sVC71_ROOT=C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7" "--prefix=C:\projects\boost" install Within my project, I've set an additional include path of C:\projects\boost\include\boost-1_31. Now when I compile my project with one source file containing the line #include <boost/shared_ptr.hpp> I get this error: c:\projects\boost\include\boost-1_31\boost\config\compiler\borland.hpp(1 3) : fatal error C1017: invalid integer constant expression What have I missed? -- Daniel
