Question

I have C source code which i want want to build with Visual Studio 2010. It references two libraries, which i think i have added correctly to my project, see the image.

As i understand i should rename the source file to name.c in order to have compiled as C. When i build my solution I get a undefined namespace errors on AssemblyInfo.cpp.

how can i fix these errors?

Please note that I also got a .OBJ, .LIB and .MAK file with the program. When opening the .MAK file I get the following errors:

EDIT:

i recreaated the project as Win32 console project. When compile the solution I get the following errors:

Answer 1

The compiler probably doesn’t really care for the file extensions. You could look into your project’s settings: C/C++ -> Advanced -> Compile As and then select C Code (although valid C code should also be valid C++ code).

Also, the AssemblyInfo.cpp is only for C++/CLI projects. So remove that file or exclude it from the build.

It looks like created the project as a C++/CLI project, so you’ll probably have to edit more project settings, or (the best solution IMO) recreate the project file as a native C/C++ project (Like Win32 Project or Win32 Console Application).
