compile_commands.json doesn't work with WSL

Type: LanguageService

Describe the bug

• OS and Version: Win10
• VS Code Version: 1.27
• C/C++ Extension Version: 0.18.1

To Reproduce

c_cpp_properties.json:

{
    "configurations": [
        {
            "name": "WSL",
            "intelliSenseMode": "gcc-x64",
            "compilerPath": "/usr/bin/gcc",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "compileCommands":"${workspaceFolder}/../BuildOutput/cmake/ninja/compile_commands.json",
            "defines": [],
            "cStandard": "c11",
            "cppStandard": "c++17"
        }
    ],
    "version": 4
}

compile_commands.json:

{
  "directory": "/mnt/c/repo/BuildOutput/cmake/ninja/test",
  "command": "/usr/bin/g++  -D_CROSS_PLATFORM=1 -isystem /mnt/c/repo/vcpkg/installed/x64-linux/include   -Wall   -std=gnu++1z -o CMakeFiles/test-statops.dir/test_c1.cpp.o -c /mnt/c/repo/DspOps/test/test_c1.cpp",
  "file": "/mnt/c/repo/DspOps/test/test_c1.cpp"
}

Expected behavior

I expect the WSL paths from compile_commands.json to get translated to the corresponding Windows paths.

I have run into the same issue. Is there any update on whether this should be supported?

[sean-mcmanus]

No update yet. Maybe we could look at this at the same time we look at the similar WSL compilerPath issue at #2978 .

I've come up against the same problem when using WSL. Since it has only been a short time since the last comment I'm assuming that the status has changed, but hopefully in the next release.

[flamtapgt]

Consider using the new Remote-WSL extension (if you can use the Insiders release)

Thanks, @flamtapgt, this is very interesting. I'll have to take a closer look once I figure out how to test it without breaking my current setup. I am doing embedded development and use a usb based debugger and the Cortex-Debug extension to debug. I'll have to try it out and see if I can still get these extensions working as needed.
