Find source files referenced via wildcards in the makefile so that IntelliSense works for them too

[drimmeer]

Bug type: Language Service

Describe the bug

• OS and Version: Windows Server 2012 R2 standard
• VS Code Version: 1.55.2
• C/C++ Extension Version: 1.3.1
• Other extensions you installed (and if the issue persists after disabling them): Make File Tools 0.2.0
• If using SSH remote, specify OS of remote machine: N/A
• A clear and concise description of what the bug is, including information about the workspace (i.e. is the workspace a single project or multiple projects, size of the project, etc).

I have only one very small c project loaded into VScode. It worked well at the beginning.
But from some time on, it could not go to the 'Reference' or 'Definition' or 'Declaration' of any method.
Then later, some more serious problem happened: I found in the 'Problem' view that any opened c code was reported there showing error message "command-line error: language modes specified are incompatible"

BTW, the 'Build' runs well successfully. That means the c codes have no problem.

Steps to reproduce

1. Click on one c program and open it in the Editor.
2. Go to the 'Problem' view, you will see that it shows error "command-line error: language modes specified are incompatible" which directs you to the first line of the code.

Expected behavior

I would like to be able to go to a method referencing places, definition and declaration places. Also there should not be such errors "command-line error: language modes specified are incompatible".

• Logs from the language server logging

[sean-mcmanus]

Something is incorrectly causing the c++17 standard version to be used. Can you set your C_Cpp.loggingLevel to "Debug" and check your "C/C++" logging to see if you can see where it might be going wrong (i.e. any errors after "Compiler query command line"?

Looks like something is causing the extension to believe the file is C++ and not C. Does the language mode in the status bar say "C" or "C++"? Can you check your files.associations setting?

I'm not able to repro the issue, so I'm not sure what's going wrong yet. We don't appear to be getting any configuration info from the makefile extension.

Does your compiler version support gnu17?

[petr-nechaev]

I had the same problem, vscode tried to compile "c" file as c++17 fo intellisense so I got "language modes specified are incompatible" error.

Removing "configurationProvider": "ms-vscode.makefile-tools" from configuration resolved the problem. I hope this sheds some light on the problem.

[andreeis]

@petr-nechaev and @drimmeer, please share .vscode/dryrun.log and the output channel of a configure (with "makefile.loggingLevel": "Debug"). Also give one example of source file where this symptom occurs, so that I follow any references of that source in these logs.

[drimmeer]

Thanks @sean-mcmanus @andreeis and @petr-nechaev .
I accidentally solved the problem by disabling the makefile extension, undoing all my changes, and then enabling the makefile extension.

[andreeis]

@drimmeer, good to hear that. For the future, anytime you see IntelliSense problems and you're using Makefile Tools, here are some easy steps to identify whether this extension does something wrong or not:

• search for the source file path that has red squiggles in .vscode/dryrun.log. If you don't find a compiler invocation for this source file, then you need to figure out in your makefile why it's been excluded (maybe you didn't hook it to your build yet, or you loaded a makefile configuration that builds a subset of your project, leaving that source file out). Your file should be processed by a "make --dry-run --always-make" command, otherwise we can't know about it.
• once you find that the dryrun invocation of make is compiling your source file, set "makefile:loggingLevel": "Debug", then search in .vscode/extension.log (which gets created after setting "makefile.extensionLog": ".vscode/extension.log") or in the output channel for "sending configuration for file" and/or "sending configuration (from cache) for file". There you will see what defines/includes/standard/other flags were parsed by the extension and sent to CppTools. These parsed flags should match your command line and should match what CppTools receives.

[drimmeer]

Thank you @andreeis for the advice! I'll keep this in mind.

[olimexsmart]

Hi, I'm sorry to reopen this, but I systematically have to follow @drimmeer suggestion of disabling the extension, reload window, enabling again.

I have to do this once or twice in a typical work day. Considering that my dry run takes more than a minute to complete, it is a significant pain.

Can I help somehow to have this problem solved?

Thanks

[andreeis]

@olimexsmart, I am very sorry to hear that. Let's see how we can improve your experience asap.
I still have no idea how the uninstall/install of the Makefile Tools extension can have an impact here, but let's follow the usual clues to finding what is wrong either in the extension (bug) or in setting up the repository.

Is your project public (github?) and you can share it whole for us to have a look without asking you too many things?

If not, follow the bullets from 3 replies above and share us those files.

[olimexsmart]

search for the source file path that has red squiggles in .vscode/dryrun.log. If you don't find a compiler invocation for this source file, then you need to figure out in your makefile why it's been excluded (maybe you didn't hook it to your build yet, or you loaded a makefile configuration that builds a subset of your project, leaving that source file out). Your file should be processed by a "make --dry-run --always-make" command, otherwise we can't know about it.

In my case when this error shows up, every file in my project has the error.

once you find that the dryrun invocation of make is compiling your source file, set "makefile:loggingLevel": "Debug", then search in .vscode/extension.log (which gets created after setting "makefile.extensionLog": ".vscode/extension.log") or in the output channel for "sending configuration for file" and/or "sending configuration (from cache) for file". There you will see what defines/includes/standard/other flags were parsed by the extension and sent to CppTools. These parsed flags should match your command line and should match what CppTools receives.

I'm not sure if this is what you are interested in. Sadly I cannot share the project because it is an embedded proprietary code. The MCU is not even openly available to the public. I had to substitute some output with /* */.

Just to be clear: I opened this morning the project and it was fine. To reproduce the error, I just reloaded the windows and it was there. Moreover, I work with multiple VSCode opened on this kind of projects and opening both, one was fine, the other one was not. It almost seems there is a state/cache per-project somewhere that is not properly cleaned. Once the error is there, I can now reload the windows indefinitely and the error stays there.
