RE: nRF Connect for VS Code no longer building project

Maybe this can help to fix the issue.

These are the steps how I can consistently reproduce the issue:

1. Create a folder test-workspace

2. Open the folder test-workspace in VS Code

3. Create the file ".devcontainer/devcontainer.json" and add the following content to this file:

{
    "image": "ghcr.io/nrfconnect/sdk-nrf-toolchain:v3.1.1",
    "customizations": {
        "vscode": {
            "extensions": [
                "nordic-semiconductor.nrf-connect-extension-pack"
            ]
        }
    }
}

4. Press F1 in VS Code and select "Dev Containers: Reopen in Container"

5. Use the internal bash terminal of VS Code to execute:

west init -m https://github.com/nrfconnect/sdk-nrf.git --mr v3.1.1 . && west update

6. Create the file ".vscode/settings.json" and add the following content to this file:

{
    "nrf-connect.toolchainManager.installDirectory": "/opt/ncs",
    "nrf-connect.applications": [
        "${workspaceFolder}/nrf/applications/nrf_desktop"
    ]
}

7. Press F1 in VS Code and select "Developer: Reload Window"

8. Add build configuration with this settings:
- Board target=nrf52840dk/nrf52840
- Base config file=configuration/nrf52840dk_nrf52840/prj.conf
- Generate only=True
- Everything else should be untouched

9. Building should fail with similar error message:

Hello Priyanka,

I am having the exact same issue as David and can not build my projects. Please do not give up.

Hi David,

I am checking this internally with the team. Similar issue has been reported, but I am not able to reproduce it here. I am discussing this with experts and will get back to you as soon as I get a solution.

Hi Priyanka,

when I'm building in the SDK path I have the same issue. I tried it with both versions I have installed 2.0.2 and 2.6.1. Before building I deleted the build folder.

Hi David,

I am not able to replicate your error.

Could you try to build within the actual path and see if the issue arises?, i.e. build within C:\NCS\v2.6.1\nrf\applications\nrf_desktop\

instead of creating a separate workspace at c:\project\debug

Please try this and let me know how it goes. Also, please delete the existing build file and application as well and do a fresh build in the new location.

Regards,

Priyanka
