Hi Andreas, Not sure this problem has something to do with Boost (if it has at all, I believe it's something for the boost.user list). I cannot tell you what exactly goes wrong, due to the lack of information (verbose linker output, command line of invocation). The right C++ standard library isn't loaded by the linker. This can have the following reasons: - You are linking the program (or your static library) with a static runtime library but a library you are using does want to link with a dynamic one (the __imp prefix indicates a missing import library). In this case make sure to set the right runtime-linkage while building boost. - You are invoking the linker with NODEFAULTLIB(S) options or NODEFAULTLIB options have been toasted into a static library you are trying to use (via #pragma). I can't imagine boost developers doing things like this - but I've met (non-boost) libraries with the "little bit of extra-horror" inside ;-). - The default calling convention used by the standard library differs from the one used to build the program (or your static library), so the inlined code tries to call a routine which is not there. However, '__cdecl' looks OK, unless you recompiled your standard C++ library. (I might have forgotten something.) Verbose linking is a good idea to track down the problem.

Hi there,
I'm getting linker errors when I'm trying to compile my application with VS.2003 and boost-1.32. The application uses a DLL which doesn't use parts of the STL or boost, only the application itself and a static library (which contains the major parts of the code) are using boost, STL and MFC code.
