I tried Build blender2.8 : cmake error, but I have produced same error. My CMake version is 3.12.2.

Following is terminal output.

D:\blender_dev\blender>make.bat

CMakeError.log says that can not open CMakeCCompilerId.c. But CMakeCCompilerId.c exists. I cite a part of translated CMakeError.log.

Compiling the C compiler identification source file “CMakeCCompilerId.c” failed.

When I open the CompilerIdC.vcxproj in MSVC, the full path of the source file have been broken.

Folder nest would have problem. When move CompilerIdC to D:/, the project can compile in MSVC.

Is this able to fix?

Looks like the C++ compilers are missing, Be sure you have the Desktop development with C++ workload selected in the visual studio installer.

I have installed MSVC several times. But it did not solve the problem. My Desktop develolpment with C++ workload has following options.

  • Just-In-Time debugger
  • latest VC++ 2017 15.8 v14.15
  • Windows 10 SDK(10.0.17134.0)
  • Visual C++ tool for CMake
