I am using boost.python to wrap C++ function which includes directmusic libraries to simply play the midi, but lots of linkage errors "error LNK2001: unresolved external symbol". I wonder if it is possible to work with DirectX - directmusic libs. Are there any ways to wrap it? *********************compilation errors *************************

Any ideas? Thanks so much for your help
The errors you posted appear to have nothing to do with Boost. It looks like you just need to link to the correct libraries.
If you have double checked and are already linking to the correct libraries, double check that the latest DirectX paths are searched first to guarantee that the linker isn't picking up previous versions of DirectX libs. Hi Michael
Thanks for your reply. I'll double check, but I've also put those header files inside the boost folder and include as
#include <boost/python/dmusicc.h>, but still failed
Well, I don't think header files are the problem - it's the libraries, since it's a linker error. If you have already specified in the Project Linker settings the correct libraries to link to, you need to check your library path settings in Visual Studio. Click on Tools, Options, Projects and Solutions, VC++ Directories, then Show Directories for Library files, and move the directory that contains the libs you want to link against up to the top (or at least above anywhere else older versions of the libraries could reside). You might also double check the Additional Library Directories setting in your Project Settings (if you are using it) to make sure it points to the right path. Good luck, --Michael Fawcett P.S. Please don't top post. I rearranged your post above.
