Why does ALE's linting omit the -Xclang compiler flag even though it is inside the compilation database?
Information
VIM version
NVIM v0.6.1 Build type: Release
Operating System: macOS 10.15.7
What went wrong
I have ALE configured like this:
call dein#add('dense-analysis/ale')
let g:ale_linters = { 'cpp' : ['clang', 'clangtidy'] }
let g:ale_cpp_clangtidy_checks = []
let g:ale_cpp_clangtidy_executable = '/usr/local/Cellar/llvm/13.0.0/bin/clang-tidy'
let g:ale_c_parse_compile_commands=1
let g:ale_cpp_clangtidy_extra_options = '-p compile_commands.json'
let g:ale_cpp_clangtidy_options = ''
let g:ale_set_balloons=1
let g:ale_linters_explicit=1
let g:ale_c_build_dir_names=['build', '.']
I have compile_commands.json both in the build dir and symlinked to project root. Inside are commands like this for the file in question (src/main.cpp):
{
"directory": "/project/build",
"command": "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++ -DBOOST_ALL_NO_LIB -DBOOST_DATE_TIME_DYN_LINK -DBOOST_FILESYSTEM_DYN_LINK -DBOOST_IOSTREAMS_DYN_LINK -DBOOST_SERIALIZATION_DYN_LINK -DBOOST_SYSTEM_DYN_LINK -DCORE_DEBUG -DDISABLE_PCAP -DDISABLE_PNG -DEIGEN_MAX_ALIGN_BYTES=32 -DJSON_USE_IMPLICIT_CONVERSIONS=1 -DQT_CORE_LIB -DQT_GUI_LIB -DQT_WIDGETS_LIB -DTBB_SUPPRESS_DEPRECATED_MESSAGES -DWITH_OUSTER -DWITH_QT -DWITH_SPINNAKER -DXTENSOR_USE_TBB -DXTENSOR_USE_XSIMD -DvtkRenderingCore_AUTOINIT=\"3(vtkInteractionStyle,vtkRenderingFreeType,vtkRenderingOpenGL2)\" -/project/build -/project/src -/project/tools/lidar/pcd_browser -isystem /project/deps/include/spinnaker -isystem /usr/local/include -isystem /project/deps/include/eigen3/unsupported -isystem /project/deps/include/eigen3 -isystem /project/deps/include/pcl-1.12 -isystem /project/deps/include -isystem /usr/local/opt/[email protected]/include/vtk-8.2 -isystem /usr/local/include/opencv4 -isystem /project/build/psiact/include -isystem /usr/local/include/optional-lite -iframework /usr/local/opt/qt@5/lib -isystem /usr/local/opt/qt@5/lib/QtWidgets.framework/Headers -isystem /usr/local/opt/qt@5/lib/QtGui.framework/Headers -isystem /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk/System/Library/Frameworks/OpenGL.framework/Headers -isystem /usr/local/opt/qt@5/lib/QtCore.framework/Headers -isystem /usr/local/opt/qt@5/./mkspecs/macx-clang -isystem /project/third_party/autocrane-utils/include -Xclang -fopenmp -DWITH_OPENMP -g -g -O0 -fno-omit-frame-pointer -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk -mmacosx-version-min=10.15 -Wall -Wextra -Wnarrowing -Werror=unknown-pragmas -Werror=uninitialized -Werror=return-type -Werror=non-virtual-dtor -Werror=parentheses -Werror=old-style-cast -Wno-unused-parameter -Wno-unused-function -Wno-pragmas -Werror=format -Wunreachable-code -Wno-error=unused-variable -Wextra-semi -ferror-limit=2 -Werror=unused-private-field -Werror=return-stack-address -Werror=mismatched-new-delete -Werror=implicit-fallthrough -Wmost -msse4.2 -mfpmath=sse -march=native -mavx2 -fPIC -Xclang -fopenmp -std=gnu++14 -o CMakeFiles/execurale.dir/src/main.cpp.o -c /project/src/main.cpp",

},
The project uses OpenMP which on Apple Clang needs the -Xclang flag before -fopenmp, which you can find in the above excerpt. However, as per :ALEInfo, the compiler invocation run by ALE does not have this flag:

clang: error: unsupported option '-fopenmp'
So for some reason, the flags used by ALE's compiler invocation are missing something
Reproducing the bug
- Make a CMakeProject that uses OpenMP and exports compilation database
- Configure ALE as above
- Open cpp file from the project
- ???

Anyone got an idea about this? Seems to make ALE useless for any project that uses OpenMP
