stefanullinger to me I updated and wanted to compile SDL, but it does not work. The reason is the new pre-build step. Currently it says: "if exist $(SolutionDir)\..\include\SDL_config.h goto SDLCONFIGOKAY echo Copying SDL_config_win32.h to SDL_config.h... copy $(SolutionDir)\..\include\SDL_config_win32.h $(SolutionDir)\..\include\SDL_config.h :SDLCONFIGOKAY if exist $(SolutionDir)\..\include\SDL_revision.h goto SDLREVISIONOKAY echo Creating stub SDL_revision.h file... echo #define SDL_REVISION 0 >$(SolutionDir)\..\include\SDL_revision.h :SDLREVISIONOKAY" So ... the problem with this lines is, that they lookup the SolutionDir... I think it should use the ProjectDir here! I - for example - want to use SDL within my engine... So my engine is the solutionDir...not SDL...SDL is just a sub-project. I think you should change this, shouldn't you?! Regards, Stefan
