VSCODE reports symbols not found, while jump to declaration works correctly.

@MaJerle C/C++: Log Diagnostics should appear when you have a C/C++ file active.

I agree, thanks. it is below.

Some notes:

• CMake tools does not use GCC from mingw, but compiler is ARM GCC instead. Not sure why it shows path to msys64 (I have GCC compiler there, but we don't compile target with this one)
• file iwdg.c is added to the target with target_sources cmake functions. This file works fine
• file adc.c is added to the target via add_subdirectory(...) and then we link the library from the subdirectory. This file has problems

There is clearly a disrepancy.

I tested same project with 2 different computers and result is always the same.

------- Workspace parsing diagnostics -------
Number of files discovered (not excluded): 3788

[MaJerle]

Update: for test, I moved from the add_subdirectory approach, to file(GLOB_RECURSE...) instead.
Now all files are added to the project as a target, and not as a library anymore.

And it works fine.

Is it therefore vscode-cmake-tools issue?

[sean-mcmanus]

@MaJerle I think so. From your logging, I don't see a configuration being sent from CMake Tools.

[MaJerle]

Edit: No, after I closed the window and opened again, it stopped working again, regardless of how cmake is configured.

[sean-mcmanus]

@MaJerle Sorry, I thought our Log Diagnostics logging showed the "Custom configurations received:" logging but it's actually in our main C/C++ logging when C_Cpp.loggingLevel is set to "Debug". Do you see the correct "Custom configurations received:" info being sent from CMake Tools? i.e. the correct includes/defines/args/compilerFragments.

[MaJerle]

I'm not getting correct data if I well understood your point.

I'm testing on 2 PCs, same project, and something seems to be wrong with CMake Tools extension, because suddenly it starts working (random) and as soon as I restart vscode, errors appear again
