The configuration provider sends msvc intelliSenseMode for IAR compiler #1096

pfox89 · 2020-02-25T19:56:36Z

Brief Issue Summary

When a compiler cmake-tools is not familiar with is used by CMake (e.g. an embedded compiler with a custom toolchain file), it ignores all other settings and defaults to the MSVC Intellisense mode on Windows. This is usually undesirable, since embedded code is not generally compatible with MSVC.

Expected:

There should be a way to manually override the intellisense settings on a project basis (possibly in cmake-kits.json?) so it can be used as a configuration provider even if the compiler being used by cmake is not supported.

C/C++ log file

In the log below it can be seen that the settings specified in c_cpp_properties.json are not respected and msvc intellisense mode is used when the IAR compiler is specified by a cmake toolchain.

Other Notes/Information

Clang may be a better fallback if the compiler can't be identified, since it's probably the most broadly compatible.

Easy to change the default. We could also add a new setting for this.

andreeis · 2020-03-06T23:27:20Z

Also, can you run your scenario again, after setting the CppTools logging level to "debug" (https://code.visualstudio.com/docs/cpp/enable-logging-cpp) and share with us the configurations sent by CMake Tools to CppTools? Look for "custom configurations received". You can also share the whole log and we will parse through it for helpful information.
It could be a bug in CppTools and not in CMake Tools.

andreeis · 2020-04-01T17:59:12Z

Let us know if this is still an issue for you. If it is, please provide the logs (as explained above).

OK, I have gotten a log. I've had to blank out some file names and private information, but that is mostly not relevant to this issue:

Unfortunately, this is not the log we are looking for. We need you to turn on the C_Cpp.loggingLevel setting and look in the Output window for the "custom configurations received" so we can see if CMake Tools is sending the right compiler info.

https://code.visualstudio.com/docs/cpp/enable-logging-cpp

pfox89 · 2020-04-01T18:54:06Z

My workspace config is as follows:

{
	"folders": [
		{
			"path": "."
		}
	],
	"settings": {
		"C_Cpp.loggingLevel": "Debug"
	}
}

I'm not seeing any output with "custom configurations received" in the Output Window. Is some other step required to get this?

Maybe this is what you're looking for?

From this it looks like "intelliSenseMode": "msvc-x64" is in the configuration that cmake-tools sends to C/C++. It does also send a compiler path, which C/C++ tries to query, but fails because the compiler is not supported.

Thank you. This log helps a lot. I thought you were using C:\\Program Files (x86)\\GNU Tools Arm Embedded\\9 2019-q4-major\\bin\\arm-none-eabi-gcc.exe which I expected would be supported. The IAR compiler isn't supported yet.

pfox89 · 2020-04-01T21:03:26Z

Sorry, yes, I actually did try to specify the arm-none-eabi-gcc compiler in my c_cpp_properties.json in hopes that it would use that as a fallback, but it only appears to do that sometimes.

It looks like if I change that after doing the CMake config, it takes until the next time I configure or reopen VS Code, so I think cmake-tools is overriding that setting with the IAR compiler path, which doesn't configure correctly.

What I'd like to be able to do is to have cmake-tools fall back to a manual configuration for the compiler if the compiler is not supported instead of pushing an unsupported config which will break Intellisense.

bobbrow · 2020-04-01T21:06:15Z

What you may need to do for the time being is use compile_commands.json instead of the configuration provider. CMake Tools should generate this file for you. When you use compile_commands.json, you can override the compiler with the value in compilerPath and hopefully that will get things to start working for you until we come up with a plan for IAR.
