带特殊符号的CMake路径

Question

我正在使用 CLion，每当我在处理一个项目时，它不能在带有特殊符号的路径中（例如 º、 ç、ã...)，失败并显示以下消息：

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.

Answer 1

MinGW 的 make 程序不能顺利处理非 ASCII 字符。我能够使用包含 ñ:

的路径在我的机器上重现此内容

  The C compiler

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

  is not able to compile a simple test program.

  It fails with the following output:

    Change Dir: C:/workspace/peña/build2/CMakeFiles/CMakeTmp

    Run Build Command(s):C:/apps/MinGW/bin/mingw32-make.exe cmTC_fe654/fast && C:/apps/MinGW/bin/mingw32-make.exe -f CMakeFiles\cmTC_fe654.dir\build.make CMakeFiles/cmTC_fe654.dir/build

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

注意，CMake切换到路径正确的临时构建目录，但是在执行mingw32-make.exe时，路径现在是乱码：

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

避免此问题的最简单方法是简单地将您的项目路径更改为不包含非 ASCII 字符的路径。

另一种选择是使用不同的生成器（MinGW Makefiles 以外的生成器）。例如，Visual Studio 可以正确配置和构建，即使非 ASCII 字符位于项目路径中：

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