CMake path with special symbols

I'm using CLion and whenever I'm working on a project, it can't be in path with special symbols (such as º, ç, ã...), failing with the following message:

The C compiler

    "C:/Program Files (x86)/mingw-w64/i686-8.1.0-posix-dwarf-rt_v6-rev0/mingw32/bin/gcc.exe"

  is not able to compile a simple test program.
Solution

  • MinGW's make program does not handle non-ASCII characters smoothly. I was able to reproduce this on my machine using a path containing ñ:

      The C compiler

    "C:/apps/MinGW/bin/gcc.exe"

  is not able to compile a simple test program.

  It fails with the following output:

    Makefile:137: recipe for target 'cmTC_fe654/fast' failed
    mingw32-make.exe: *** [cmTC_fe654/fast] Error 2

    Note, CMake switches to the temporary build directory with the correct path, but when mingw32-make.exe is executing, the path is now garbled:

    C:/workspace/pe±a/build2/CMakeFiles/CMakeTmp

    The easiest way to avoid this issue is to simply change your project path to be one that does not contain non-ASCII characters.

    Another option would be to use a different generator (something other than MinGW Makefiles). For example, Visual Studio configures and builds correctly, even though the non-ASCII characters are in the project path:

    > cmake -G"Visual Studio 16 2019" ..
Re-run cmake no build system arguments
