Failed to generate IntelliSense configuration with STM8 Core

[0x0fe]

To reproduce the issue, install STM8 core https://github.com/stm32duino/Arduino_Core_STM8 from the board manager, select any example, one of the two boards as target, and hit "Verify".

Verification...
[Warning] Failed to generate IntelliSense configuration.

Is there a way to get some log? no long on console(s) no log in the build directory... We really shoudl get more meaningful debug on the verify and intellisense because it does fail and to fix it we have to know why.

I did my best to recreate a c_cpp_properties.json but it did not solve the problem.
N.B. the target here is a custom target, but the problem is exactly the same with the targets provided with the core.

You can get more verbose log by setting arduino.logLevel to verbose:

{
  "arduino.logLevel": "verbose"
}

well, except it doesnt work.

EDIT: i added it to settings.json and now it works, finally, however there is zero log on what causes the intellisense error, which is the concern here, the log for build is nice, but build was working anyway.

same +1

i guess we need to fix it ourselves, since neither microsoft nor ST seems interrested to help

[nya3jp]

You may want to try #1494. It fixes the issue for m5stack for me.

[0x0fe]

yes, i did not think of it, but it is a common problem indeed, I'll give a try and not thank microsoft nor ST for the non existing support

[0x0fe]

ST, a company which probably lost a huge part of it market share with the disaster of last months (welcome 1000% increase on 10 year old MCU), but still hasn't understood the importance of support. i feel like it's going to be a (well desserved) "good riddance" soon

Hi @0x0fe. I'm uable to reproduce this issue because I don't have a license for the compiler used by the STM8 tools. However, based on the earlier discussion #1494 may fix your issue, which will be included in an upcoming release. You can try it now by installing the VSIX manually from this CI build. Does that fix your issue?

Thank you for checking on the issue. I am going to try it soon when i have a chance to get back at this design, regarding the STM8 compiler "license", I think you can request one anytime here (it is automated via email) :

Since there is a VSIX i gave a try, installed the VSIX from the contextual menu of extension pane on left side. Now the "inderterminate" progress bar is running since a good 10 minutes and going, nothing has been done, it probably failed at the beginning but since there is no progress report of any kind anywhere it is left to anyone's guess. VScode is just stuck doing nothing, in loop, forever. So i guess i will not be able to test wether the fix works.

As a side note, when the user initiates an action such as installing an extension he expects a feedback on what is going on, wether it failed or succeeded, and that a timeout will prevent the whole application be be stuck forever if the action did fail, pretty basic UI concept but not obvious for everyone apparently.

I had to quit completely VScode (force quit) then i restarted it, retried the VSIX installing, and it worked. This kind of buggy inconsistence is pretty consistent with microsoft style i would say.

[0x0fe]

well, sadly it not only did not solve the problem, it also completely broke the extension, the "verify" command does not exist anymore, cannot even build.

It is also burning a lot of CPU cycles when i open the directory, without any report in OUTPUT, it is quite not acceptable to have sudden huge CPU usage without any justification or report.
