Hi, while building the boost library (trunk) we getting the following message: compiler MS Visual Studio 2005 @ win XP SP2 any help to overcome this? Thanks in advance Best regards Mike C:\boost>"bin\bjam.exe" -d 0 stage --stagedir=. toolset=msvc-8.0 link=static runtime-link=s tatic threading=multi --without-mpi architecture=x86 release debug address-model=32 warning: Graph library does not contain optional GraphML reader. note: to enable GraphML support, set EXPAT_INCLUDE and EXPAT_LIBPATH to the note: directories containing the Expat headers and libraries, respectively.
