Matter Lock example

Hi Charlie - Totally understand re: 3rd party extensions and Nordic reasonably not being in a position to police them. I should note that I am only now using the NRF Extension pack extensions and not changing the default configuration and still get a lot of warnings and errors.

That being said, I did try a couple of things that greatly reduced the number of warnings/errors reported by VS Code and I am sharing here in case it can benefit anyone else:

1) Add to your c_cpp_properties.json in VS Code the following configurations (source/credit):

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

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

2) run (source/credit):

west config build.cmake-args -- -DCMAKE_EXPORT_COMPILE_COMMANDS=ON

For now, I am going to try and ignore the issues with the dev environment and focus on development and building my application. It is still a little mysterious why we should have such different VS Code experiences if we are both starting from a clean install and I would be happy to make myself available to the Nordic team to debug it if anyone wants to do a real-time, interactive session. Thanks! Dan.

Hi Dan,

I am not sure how you create this file. I do not have c_cpp_properties.json in my current project folder or working space, the default C/C++ extensions setting should work. It is also worth mentioning the solutions mentioned on another ticket if you want to learn more.

Problems with VS Code - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

You may realize all the PROBLEMS reports are issued by assistant extensions and may be caused by improper configuration. Some of the extensions are not originally designed or optimized for Zephyr/NCS project and they are not intelligent enough for the complex structure of Zephyr/NCS like the following issue report. We have no quick solution for these kinds of problems since these extensions are maintained by other people or origination under open-source licenses. They have no influence on the building process. As long as the building process does not report errors, you can focus on your development safely.

nRF9160DK ver 0.9.0 - application software show error during build. asset_tracker_v2 in v1.7.1 - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

Hi Charlie - Thanks for digging into this further and for your suggestions which I followed (I removed all extensions, reinstalled nRF Connection Extension Pack from within VS Code, and restarted VS Code).

When it first opens up, it does indeed only show one warning. However, as soon as I click into app_task.cpp it presents 14 errors and 1 warning (it can still build and flash and work properly despite these, which leads me to believe it is a VS Code/Intellisense configuration issue and not an actual issue). However I would like to get it resolved so that when I have real issues, VS Code can alert me of them properly.

When VS Code first opens:

After clicking in to app_task.cpp:

Would you be able to share your lock/.vscode/c_cpp_properties.json file contents so I can compare to mine? Also, if you have the output from VS Code for Generate Support from an M1 Mac I would welcome having a look at it to compare it to mine.

Thanks! Dan.

Hi Dan,

After some exploration, I got the following suggestions for you:

1) Try to clean up your extensions first. Uninstall the extensions related to C/C++ first, reinstall the nRF Connect Extension Pack, restart VS Code.

2) After above step, you should see only one error and several warnings appear. The error has a solution mentioned here Kconfig.defconfig:11: error: couldn't parse 'default $(dt_node_int_prop_int,/cpus/cpu@0,clock-frequency)' · Issue #41093 · zephyrproject-rtos/zephyr · GitHub

Best regards,

Charlie

Hi Charlie - thanks for the detailed response and the info on Matter and Apple - appreciate the links and will dig into it deeper. We are good on 2,3,4 above.

Re: (1): I did as you suggested (clean restart of VSCode workspace from scratch with no changes to the lock sample code or configuration) and also left "Enable Debug Options" unselected in the build configuration dialog (previously I had enabled it). The Problems tab in VSCode now reports 4 errors and 5 warnings as below. I can still compile and flash the board and it appears to work properly, but these errors are a little annoying and also I am seeing squiggles under include files that intellisense cannot find (and as far as I can tell, it should because the cpp_properties JSON properly specifies the includePath recursively as:

my lock/.vscode/c_cpp_properties.json:

{
    "configurations": [
        {
            "name": "Mac",
            "includePath": [

So for example, when I click to edit app_task.cpp, it shows all the includes with squiggles and I can't right click through to the definitions etc... Would welcome your advice/suggestions on how to resolve this as well. Thanks! Dan.

RE: Matter Lock example

Charlie — Mon, 14 Feb 2022 15:10:45 GMT

Hi Dan,

1) Did you build with the original sample? I did the same building process and just get 5 warning reports from the subsystem shown as below, which has no effect on the application FW. Can you try to remove other applications and builds, close and reopen VS code to do a clean build again? Make sure the PROBLEMS output is empty before building. I will also try to get a Mac to see if the building environment makes any difference.
