Has anyone already successfully built Boost with the "Visual C++ Toolkit 2003", aka the free command line version of VC 7.1? I adjusted VC71_ROOT and copied "vcvars32.bat" to "bin". But there are still a lot of errors, the first one being: greg_month.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall std ::basic_string::basic_string(char const *)" (__imp_??0?$basic_string@DU?$char_tr aits@D@std@@V?$allocator@D@2@@std@@QAE@PBD@Z) referenced in function "public: static class boost::shared _ptr

Similar errors occur if I try to use the (successfully built) boost_thread-vc71-mt-1_31.lib with a sample project. Any ideas? Regards, Wolfgang Meyer
