Eclipse indexer issue (Symbol ... could not be resolved) + parallel build on windows

[newsettler_AI]

Hi,

I'm facing issue with Eclipse indexer. I have migrated to IDF v3.3 LTS not so long ago and not sure what is going wrong.

My setup:

• Windows 10 Home
• Eclipse 2018-09 (4.9.0)
• IDF v.3.3 LTS
• Toolchain (crosstool-NG crosstool-ng-1.22.0-80-g6c4433a5) 5.2.0

As testing project I'm using spiffs
https://github.com/espressif/esp-idf/tr ... age/spiffs

I'm doing everything as described here:
https://docs.espressif.com/projects/esp ... up-eclipse

Project compiles in both Eclipse and toolchain console. But after compilation is done, Eclipse have many (depends on project) errors
"Symbol XXX could not be resolved"

Main error

Please advice what is wrong...

I have tried to make whole Clean-Build path with different Indexer settings:

Interesting thing I noticed...

When I have disabled parallel build everything get as it should! All elements was found and resolved...

So it comes that on Windows(maybe on other systems aswell?) indexer cant properly resolve all if build runs on multiple threads.

So, here is solution that helped me to resolve issue

My Indexer settings:

Now clean project (can be done with enabled parallel build).
Disable parallel build.
Build project againg.
Open some files with "unresolved" issue and it should update on the fly, maybe take 1-3 seconds.
Now all "unresolved" issues should gone.

And then can build project with enabled parallel build.
