设置包含c / c ++的路径 - 相对于Visual Studio代码中的工作空间路径的项目（.json配置）

Question

I'd like to define the include paths of my c / c++ -project in vscode relative to my workspace folder. As mainfolder has a different path on every system I work on, and I don't want to always change the configuration file.

I have the following folder strucure

mainfolder
   /include1
   /include2
   /project/workspacepathofVScode

So the folder I open with vscode is workspacepathofVScode .

In my configuration file c_cpp_properties.json I used **/**/ to get from my workspace root two levels up, to include my two include folders, but it does not seem to be the correct syntax:

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceRoot}",
                "**/**/include1",
                "**/**/include2",
            ],
            "intelliSenseMode": "msvc-x64",
            "browse": {
                "path": [
                    "${workspaceRoot}",
                    "**/**/include1",
                    "**/**/include2",
                ]
            }
        }
    ],
    "version": 2
}

How can I define the include paths relative to workspacepathofVScode ? If it is not possible the way I thought, do you know any workaround?

Answer 1

Vscode doesn't support relative paths directly, but it is possible to start with a path variable containing an absolute path and then append a relative path. See the following bug discussion: Unable to resolve includes with relative paths

So for the presented case of paths thats should be relative to the workspace path, start with the workspace path variable and use ".." instead of "**" to navigate to parent folders.

The complete path for include1 should be:

"${workspaceRoot}/../../include1"
