Using MFC requires your code to include Microsoft standard header files, which clash with Toolkit header files. To resolve this, build your UNIX code with Toolkit into a stand-alone NuTCRACKER Platform DLL (see the Building Standalone DLLs in the Porting Shared Libraries chapter of the UNIX to Windows Porting Guide for more details).
Build this DLL in a Toolkit build environment. Then use VC++ to build the MFC code which loads the DLL you built from your UNIX code. (Remember the _NutEnableNuTC()/_NutDisableNuTC() calls around the UNIX code). Pay special attention to those calls which might block the thread. The MFC message cannot respond while the thread is blocked in a NuTCRACKER call.
