[task 2020-07-03T08:41:18.090Z] error: invalid argument '-std=c++17' not allowed with 'C' [clang-diagnostic-error]

Those files shouldn't have the -std=c++17 attribute passed to the command in compile_commands.json, probably they should have -std=gnu99 like the rest of the c files. Probably they must be set in the directory, something like CFLAGS += ['-std=gnu99']?

The severity field is not set for this bug.
:andi, could you have a look please?

For more information, please visit auto_nag documentation.

This should be closed since the target files no longer exist.

Resolution: --- → INVALID

We still have C files in the tree. I don't see why things would be different for them.

Resolution: INVALID → ---

Looking at compile_commands.json the rest of C files look to have the right standard passed to command, -std=gnu99. So this issue nor anything related to this doesn't happen anymore.

Are you sure this is til the case?

It seems I have the same issue here:

compile_commands.json seems correct, but it happens when running mach static-analysis check <c file>. The problem comes from python/mozbuild/mozbuild/code_analysis/ line 560 which adds -extra-arg=-std=c++17; by removing that line, the static analysis succeeds.

I don't know how to fix it, one could add an if *.cpp in sources? but in my case (D139533), _get_clang_tidy_command gets called with 2 mixed sources files: one .c and one .cpp.
