So, I actually went ahead and generated some MSYS makefiles and made a
compile_commands.json, and it doesn't work with clang-tidy. You get this kind
of output:
[
{
"directory": "C:/src/test_proj",
"command": "\"/C/Program
Files/mingw-w64/x86_64-6.1.0-win32-seh-rt_v5-rev0/mingw64/bin/g++.exe\"
-Dsomething\\evil -o CMakeFiles/foo.dir/foo.obj -c /C/src/test_proj/foo.cpp",
"file": "C:/src/test_proj/foo.cpp"
}
]
...
$ clang-tidy foo.cpp
1 error generated.
Error while processing C:\src\test_proj\foo.cpp.
error: error reading '/C/src/test_proj/foo.cpp' [clang-diagnostic-error]
Hypothetically we could make this work, but there are bigger problems here. In
that light, I think we should go with this patch. Long term, we should solve
this problem by emitting "arguments" or "command_shell" in cmake.
