Describe the bug

  • OS and Version: Windows 10
  • VS Code Version: 1.28.0
  • C/C++ Extension Version: 0.19.0
  • Other extensions you installed (and if the issue persists after disabling them): ms-python.python and robertohuertasm.vscode-icons. the issue persist if I disabe them
  • I have all of the include paths reported by my compiler (g++) in the include path, and still my file is filled with red lines.

For some reason, if I re-saved the c_cpp_properties.json file, even without making any changes, all of that red squiggly lines go away.

AEM5299 picture AEM5299 on 11 Oct 2018

We had some bugs with squiggles not updating correctly. https://github.com/Microsoft/vscode-cpptools/releases/download/0.19.1-insiders/cpptools-win32.vsix may have fixed the issue.

unfortunately it didn't

AEM5299 picture AEM5299 on 12 Oct 2018

So you're still getting incorrect squiggles? Can you set your C_Cpp.loggingLevel to "Debug" and check if the g++.exe compiler is getting queried correctly? It sounds like the compiler defines might not be getting set correctly.

sean-mcmanus picture sean-mcmanus on 12 Oct 2018

How to check if the compiler is queried correctly?

AEM5299 picture AEM5299 on 14 Oct 2018

@AEM5299 you should enable debug logging, reload the window and then take a look at the logs in the Output window. You can also share the output here if you are unable to find the relevant section.

I guess it is relevant to "stdver".
And I wonder that why the intelliSenseMode is "msvc"?I have set it to "gcc-x64".
Excuse me,my English is not good.

@a2757326588, for MinGW, you should be setting the "compilerPath" property in c_cpp_properties.json or else the system defines will not be set properly. Take a look at this guide.
