Visual Studio Code on macOS + Qt + Intellisense

Question

Visual Studio Code gets the following error:

cannot open source file "QtWidgets/qtwidgetsglobal.h" (dependency of "QApplication")C/C++(1696)

I have a CMake project which compiled and built successfully, but it seems that Intellisense doesn't work.

I have this directory in a path which contains qtwidgetsglobal.h:

/usr/local/Cellar/qt/5.13.1/lib/QtWidgets.framework/Headers

And there is another thing:

Directory /usr/local/Cellar/qt/5.13.1/lib/QtWidgets.framework contains directory Headers and strange executable QtWidgets I was assumed to include -I/usr/local/Cellar/qt/5.13.1/lib/QtWidgets.framework because QtCreator has both /usr/local/Cellar/qt/5.13.1/lib/QtWidgets.framework and /usr/local/Cellar/qt/5.13.1/lib/QtWidgets.framework/Headers but nothing worked.

Actually Visual Studio Code seems to ignore if both directories /usr/local/Cellar/qt/5.13.1/lib/QtWidgets.framework and /usr/local/Cellar/qt/5.13.1/lib/QtWidgets.framework/Headers specified.

Any suggestions how to enable Intellisense to work with Visual Studio Code.

Answer 1

You need to use the compileCommands instead of the cake-tools configurationProvider.

Therefore in your c_cpp_properties.json add the line

"compileCommands": "${workspaceFolder}/build/compile_commands.json",

and remove

"configurationProvider": "ms-vscode.cmake-tools",

The full config file should look something like this

{
    "configurations": [
        {
            "name": "Mac",
            "compilerPath": "/usr/bin/clang",
            "compileCommands": "${workspaceFolder}/build/compile_commands.json",
            "browse": {
                "limitSymbolsToIncludedHeaders": true
            },
            "macFrameworkPath": [
                "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks"
            ],
            "cStandard": "c11",
            "intelliSenseMode": "clang-x64",
            "cppStandard": "c++14"
        }
    ],
    "version": 4
}
