尝试在 Windows 7中构建nanomsg 项目时出现错误:
cmake ..
-- Building for: NMake Makefiles
-- The C compiler identification is GNU 4.7.1
-- Check for working C compiler: C:/Program Files (x86)/CodeBlocks/MinGW/bin/gcc.exe
CMake Error: Generator: execution of make failed. Make command was: "nmake" "/NOLOGO" "cmTC_5d837\fast"
-- Check for working C compiler: C:/Program Files (x86)/CodeBlocks/MinGW/bin/gcc.exe -- broken
CMake Error at C:/Program Files (x86)/cmake-3.9.4-win64-x64/share/cmake-3.9/Modules/CMakeTestCCompiler.cmake:51 (message):
The C compiler "C:/Program Files (x86)/CodeBlocks/MinGW/bin/gcc.exe" is not
able to compile a simple test program.
It fails with the following output:

CMake will not be able to correctly generate this project.

我使用gcc
编译器和make
工具链Mingw
,我可以在一个简单的例子中成功运行。gcc.exe
mingw32-make.exe
在文件CMakeCache.txt
中缓存变量设置如下:
//C compiler
CMAKE_C_COMPILER:FILEPATH=C:/Program Files (x86)/CodeBlocks/MinGW/bin/gcc.exe
//Program used to build from makefiles.
CMAKE_MAKE_PROGRAM:STRING=nmake
我认为问题来自CMAKE_MAKE_PROGRAM
它应该采用的变量C:/Program Files (x86)/CodeBlocks/MinGW/bin/mingw32-make.exe
,但是我不明白它从哪里获得价值nmake
。
即使我手动更换它,我也会遇到同样的问题。
我的问题:
- CMake 如何填充缓存变量?
- 为什么要
CMAKE_MAKE_PROGRAM
取值nmake
? - 为什么手动更改此变量没有解决问题?
