I've created an EFR32 RAIL project from the Simple Rail with Hal template. When building I get the following warning:
Invalid project path: Include path not found
Of course I have no SiliconLabs-Restricted directory on my system. And thus I removed it from the project settings.
Now the issue is that I cannot get rid of the warning in the Problems View. I've already freshened and rebuilt the C/C++ Index, but it doesn't help. Restarting Studio also has no effect. How am I supposed to get rid of it?
That is an annoying warning, I'm not sure why that include path is included in the project. I was able to remove the warning by removing that path from the project properties GNU ARM C Compiler -> Includes and hit "Apply" and then also remove it from the GNU ARM Assembler -> General tab Include paths and also hitting "Apply" and then 'OK'. If I just hit 'OK' it seemed like it got added back to one or the other places.
I hope that resolves the issue for you.
