Multiple include errors generated when use cmake-tools as a configuration provider for cpptools

[Matt Whitaker (M-Whitaker)]

Hi, when using CMake Tools as a configuration provider for intelisense etc. I get an issue when the whole of the C/CPP Standard library is not included and therefore I get the error:

#include errors detected based on information provided by the configurationProvider setting. Squiggles are disabled for this translation unit

#4350 mentions this in detail however never got an answer of what is going wrong...

Things I have tried:

• Including the manual include path to the standard library
• Removing the configuration provider "ms-vscode.cmake-tools" which does solve the issue but then does not have the includes for my cmake project....

My personal setup (Though from looking at others issues I don't think this is the problem)

• MacBook Pro 13" M1
• Big Sur 11.1
• VSCode:

We need more repro info. Such as from running the C/C++: Log Diagnostics command. That command should show what include paths, compilerPath, and compilerArgs we're getting from CMake Tools and also what IntelliSense ends up using.

Also, #4350 just describes the same symptom for which there could be many different root causes.

I thought that might be what was needed. Here is the output of the debug command. As I see it seems to be including the correct Standard Library Folders for macOS along with the includes that are setup in CMake. Note: I have the most basic of c_cpp_properties.json file with just the "configurationProvider" set as per the documentation for use of CMake with this plugin.

Many thanks for any help as I know this question comes up all the time in different forms...

This is bug #6992 (the -isysroot isn't getting handled correctly) -- we're planning to release a fix with 1.2.2 today.
