Unable to resolve compiler configuration.

[da151575]

Environment

• OS and Version: Windows 11 Versino 23H2 (OS Build 22631.3737)
• VS Code Version: 1.90.2
• C/C++ Extension Version: 1.20.5
• If using SSH remote, specify OS of remote machine: Ubuntu Linux 20.04

Bug Summary and Steps to Reproduce

Bug Summary: I have configured the C/C++ module to use a cross compiler to build code for an NXP i.MX8 on a remote machine. When I start vscode on the folder containing this project, I get this error:

Unable to resolve configuration with compilerPath "aarch64-poky-linux-g++". Using "/opt/ren-dpu-mtintf/5.15-kirkstone/sysroots/x86_64-pokysdk-linux/usr/bin/aarch64-poky-linux/aarch64-poky-linux-g++" instead.

But in the configuration the compiler path is already set to /opt/ren-dpu-mtintf/5.15-kirkstone/sysroots/x86_64-pokysdk-linux/usr/bin/aarch64-poky-linux/aarch64-poky-linux-g++.

To simplify, if I set compilerPath to <full_path>, I get an error saying "can't set compiler to <leaf_name>, using <full_path>", which doesn't make sense.

Steps to reproduce:

1. Set compiler path to a given full path name
2. Restart project
3. See error
4. Intellisense is unable to find basic C++ header files, e.g. cstdint

Expected behavior:

1. Set compiler path to a given full path name
2. Restart project
3. Not see error
4. Intellisense is ableto find basic C++ header files, e.g. cstdint

da151575 You have the Makefile Tools extension installed -- it seems like you're not properly configured with that extension or it has a bug -- it's sending us the invalid "compilerPath": "aarch64-poky-linux-g++", as part of the browse configuration and it's not sending us a configuration for the source file you have opened. If you have a configurationProvider set, you generally shouldn't set the compilerPath, and you shouldn't have system includes in the includePath. Are you able to properly configure the Makefile Tools extension? Otherwise, can you change your configuration to not use that?

[da151575]

I see... I was not able to modify the Makefile Tools configuration in a way that prevented this error, and disabling it in the current workspace also didn't work. So I've removed it completely, as it isn't really adding much value. And voila, the problem is resolved. Thanks very much for taking the time to look at this.
