Failed to generate Intellisense information with EWARM 8.22.1

[Ayumiiw]

When opening a project folder which use EWARM 8.22.1 in VS Code, it failed to generate Intellisense information with the following error message. And Intellisense does not work for C standard libraries header.

Click "Show output window", then could see the following error.

<there was iarbuild log.  it succeeded>
..
WARN: Builder closed without reaching linking stage.

The error message means that iarbuild did not exit correctly, but it is difficult to tell why without more information. Could you post the last portion of the iarbuild log above?

Do you have this problem with all projects you open or only this one?

[Ayumiiw]

I tested with the tutorial projects from IAR Information Center. Intellisense error happens with

• GettingStarted - Basic debugging
• Adbanced Debugging

Does not happens with

• Language support
• Linker and libraries (But C standards libraries header path was still not resolved.)

The output windows message is as follows: [GettingStarted - Basic debugging project]

Preparing intellisense information for 'BasicDebugging'.

Seems the build stops before finish the build.

Thanks, I am able to reproduce the problem. Running a 'clean' on the project and reloading VS Code seems to temporarily fix it.

I have not been able to find what causes it, but the problem does not occur with EWARM 8.40. Most likely this is a bug in iarbuild that has been fixed in later versions. In that case there isn't much we can do about it from the VS Code extension, and the best I can do for you is recommend that you upgrade to a newer version of Embedded Workbench if possible.

[Ayumiiw]

Thank you. I confirmed that running a 'clean' works for this issue.
