Bug Summary and Steps to Reproduce

Bug Summary:

When using msys2 gcc or arm-none-eabi-gcc on Windows with vscode-cmake-tools as C/C++ configuration provider, it works fine to build and debug, and all local header files get parsed correctly, but complaints about could not open source file of all system include headers. It also works correctly on WSL ubuntu/archlinux, so I am assuming it's a Windows specific issue. It doesn't work event with a hello world example as simple as the screenshot below.

    Liangliang Ma (@akmll) We're not receiving a configuration from CMake Tools. What does the C/C++ logging pane show after you run CMake: Configure? Do you see "Custom configurations received:"? Do you see the file being processed as C or C++ in the bottom right language status bar? Do you have any files.associations setting a .c file to C++?

    Liangliang Ma (@akmll) Also, this might be a duplicate of #13622, fixed in 1.26.1 pre-release.

    Hi Sean McManus (@sean-mcmanus), it seems different to #13622. I have tried upgrading the extension to v1.26.1, putting msys2 gcc to the top of the PATH environment, but still having this issue.

    I recreated a clean workspace and after the CMake: Configure command I can see "Custom configurations recieved:" in the C/C++ log, as you can see from the attachment.

    Another thing to mention is that in the C/C++ log it says "Failed to query command line:" for the GCC compiler but I can successfully run these following 3 commands in the integrated terminal:

    • c:/tools/msys64/ucrt64/bin/gcc.exe -g -std=c17 -m64 -Wp,-v -E -dM -x c nul
    • c:/tools/msys64/ucrt64/bin/gcc.exe -g -std=c17 -m32 -Wp,-v -E -dM -x c nul
    • c:/tools/msys64/ucrt64/bin/gcc.exe -g -std=c17 -Wp,-v -E -dM -x c nul

    All these 3 commands output the same include search paths to stderr, and different predefined macros to stdout.

    Liangliang Ma (@akmll) The output of the compiler query may not match what we are expecting from a valid query. Can you provide the output from a manual query and/or from what we're logging with C_Cpp.loggingLevel temporarily set to the hidden value of "7"?

    I have exactly the same problem. Switching to the 1.26.1 pre-release version indeed fixes it.

    Tal Raveh (@talraveh1) You're hitting #13622 and not this issue (not finding headers can have many root causes).

    Liangliang Ma (@akmll) The logs don't have enough info on why the query is failing. Can you set C_Cpp.loggingLevel to "7" temporarily and look for the logging after Compiler query command line: to see if it shows some error or if it shows the correct query results that match your manual query?

    Liangliang Ma (@akmll) Your logging shows "Querying compiler for default C++ language standard using command line: c:/tools/msys64/ucrt64/bin/gcc.exe -x c++ -E -dM nul" is occurring 2 times in a row, which can only happen if the call to gcc.exe is returning a non-zero exit code. We can add logging for 1.26.2 to log the exit code.

    Liangliang Ma (@akmll) Can you install gcc at a location where you have permissions to execute it without requiring admin permission? Or can the permissions of gcc/etc. be changed to allow non-admin execution? But I'm not sure why you'd be able to execute gcc from the terminal unless you also ran the terminal command as an admin?

    Sean McManus (@sean-mcmanus), gcc is installed to directory that does not require admin permission to run. Infact cmake and other build tools are installed to the same directory and all running properly in vscode.

    Could you help to analyze the following process dump of the extension v1.26.3 to see if there is any clue? I can see from windbg that compiler quering process is terminated inside of cpptools!msvc::start_process, but I cannot debug without the source code and symbols.

    Liangliang Ma (@akmll) The call to TerminateProcess only happens if our calls related to setting properties of a job object fail after starting the process in a suspended state. With Process Monitor, do you cpptools.exe failures related to Windows "Job" calls that are failing after initially launching the process?

    Liangliang Ma (@akmll) We may be able to just ignore the job-related failures and just launch the process anyway -- they are only being set to make sure gcc is terminated when cpptools terminates and to make sure gcc doesn't use too much memory, but I don't think they should be requirements if there's a failure.

    Liangliang Ma (@akmll) Our next 1.27.0 should have a fix for the TerminateProcess after job-related Windows API failures (we're not sure when it'll be released yet).

    Liangliang Ma (@akmll) We have a fix in https://github.com/microsoft/vscode-cpptools/releases/tag/v1.27.0 . Let us know if you're still hitting this issue -- we didn't have a repro so there could be additional failures that happen after the one that we fixed.

    Sean McManus (@sean-mcmanus), I have tested the v1.27.0 extension, although there is "Failed to enable terminate with parent for process" message in the log, the intellisense seems working properly. Thanks very much for your help.
