Header Files not adding

[Stephen]

Hi there,

I can't seem to add header files to my project. 

The header files underlined in red are not from the Nordic SDK installed from the Toolchain Manager.

I have the header files added in an inc folder and the path in the c_cpp_properties.json file.

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "C:/nordicToolchain/myapps/uart_test/inc/**"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "cStandard": "c17",
            "cppStandard": "c++17",
            "intelliSenseMode": "windows-msvc-x64",
            "configurationProvider": "nrf-connect"
        }
    ],
    "version": 4
}

Here's the error code:

Thanks in advance!

Hello!

What exactly are you trying to add to your project?

It looks like you might be trying to add libraries from a different SDK, maybe to port a project you had in an old SDK over to NCS?

If that is the case, I would advise you to not use those old libraries and instead use the libraries that are available to you in Zephyr, such as UART, scheduling, etc.

Though if you still want to include your own header files, then I haven't seen json files like these used in Zephyr.

Have a look at the typical Zephyr project structure illustrated here.

You could try to point cmake towards your source code using the target_sources build script in CMakeLists.txt as described here.

But only if you're trying to include your own header files, please do not try to include header files from old SDKs outside NCS.

Best regards,

Einar
