hello list, i have upgraded to boost 1.35.0. running under win32 using visual studio 2008, i get: lib/boost/libs/filesystem/src/exception.cpp(39) : error C2039: 'system_error_type' : is not a member of 'boost::filesystem' what should i do? get the latest from subversion ? or downgrade to 34.1 ? everything else works fine. by the way, i include #include "../../lib/boost/libs/filesystem/src/operations.cpp" #include "../../lib/boost/libs/filesystem/src/exception.cpp" #include "../../lib/boost/libs/filesystem/src/path.cpp" #include "../../lib/boost/libs/filesystem/src/portability.cpp" #include "../../lib/boost/libs/system/src/error_code.cpp" #include "../../lib/boost/libs/iostreams/src/bzip2.cpp" manually. maybe this causes the problem? thanks in advance !
