Hello... I am triing to use the boost::filesystem library. But actually i am stucked using it. I have WindowsXP without a service pack. I am using Visual Studio 6.0 installed in default folders for VS6. I am using stlport but without the iostreams. After uncompressing boost, i compiled boost with bjam with following statement: bjam "-sTOOLS=msvc-stlport" "-sSTLPORT_VERSION=4.6" "-sSTLPORT_PATH=..\stlport" "-sBUILD=debug <stlport-iostream>off" stage Compilation has no errors and all libs are build. Now i want to use boost::filesystem::path, example: #include <boost/filesystem/path.hpp> int main(int argc, char* argv[]) { boost::filesystem::path( "foo" ); } What happens, is that the program stops on that command and does nothing! If i use following code: boost::filesystem::path( "C:\\" ); System makes an kernal32 exception and crashs. Same happens when i use boost::filesystem::exists Could you please help me why that happens??? Thx Mesut
