How to Properly Configure Include Paths and Libraries in VSCode\'s `task.json` and `c_cpp_properties.json` for C Projects?

VSCode C task.json: Include Paths and Libraries

Setting up the build environment for C projects in VSCode requires specifying both include paths and libraries. This can be done in two places:

c_cpp_properties.json:

• includePath specifies the search paths for header files.
• browse (now deprecated) used to serve as an alternative include path.

task.json:

• args contains the compilation command with include paths (-I) and library paths (-L).

Configuration

1. Inclusion Directories:

Yes, it is correct to specify include paths in both includePath and args. This redundant configuration covers both the code parser (for intellisense) and the build process.

2. IncludePath vs. Browse:

The browse property is now deprecated and does not have a direct equivalent. Instead, use includePath for all include path specifications.

Sample Configuration:

// c_cpp_properties.json
"configurations": [
    {
        "includePath": [
            "${workspaceFolder}/**",
            "D:/github/dependencies/SDL2-2.0.8/include"
        ]
    }
]

// task.json
"tasks": [
    {
        "label": "build",
        "type": "shell",
        "command": "g++",
        "args": [
            "-g",
            "-ID:/github/dependencies/SDL2-2.0.8/include",
            "-LD:/github/dependencies/SDL2-2.0.8/lib/x64",
            "-lSDL2main",
            "-lSDL2",
            "-lopengl32",
            "main2.cpp",
            "-o",
            "test-sdl"
        ]
    }
]

Recommendation

Consider using an external build system like GNU Make and invoke it from tasks.json. This allows you to keep build-related information separate from VSCode's workspace configuration.

Additional Note

Make sure the C IntelliSense engine is set to "Default" in the VSCode settings to utilize the full capabilities of includePath.
