Eclipse unresolved inclusion

[CseaTec]

I had this same issue as well, and I had started out with the Hello World project using the following:

• Espressif-IDE V2.5.0
• ESP-IDF V4.4

I somehow resolved it by doing the following:

1. I created a totally new project with its own unique name (choosing not to use a template for now). NOTE that this project had similar unresolved inclusions!
2. I built this project, which had only the default lines, and it took a while to complete. After it did, the unresolved inclusions were gone.
3. I closed this project, and I also closed Hello World since it was still in my project explorer.
4. I closed the Espressif IDE entirely
5. I reopened the Espressif IDE, and now BOTH projects seem to work totally fine, with rebuilds and such, and the unresolved inclusions do not show up anymore.

Yes, it is very weird and unexplained. My best guess is that the Espressif IDE has issues with the very first project it creates, then this is somehow cleaned up with subsequent project creations. It's just a coincidence that most everyone starts off by trying the "Hello World" project template since we're trying to learn the IDE platform.

Hopefully this information helps someone else.

Mine also doesn't fix this. None of these suggestions helped. I hate ESP32 development.

Additional... Eclipse shows that <stdio.h> is an unresolved inclusion. How the heck can stdio.h not be resolved??

My unresolved inclusions got fixed by check marking the following: index unused headers as C files

It looked promising, but it didn't cut it for me.
After creating a new project from any demo project, compilation goes without errors.
Immediately after this, when entering to a C file for the first time (for example, in the file with the main() function), the errors appear.

I built the esp32 blink demo project without errors using this:
"How to disable the Unresolved Symbol error markers" from here:
https://github.com/espressif/idf-eclips ... ressif-ide

- similar to above in menu/Windows/Preferences/CC++/Indexer
- The context menu of the project/Index/Fresjen..
- From menu/Windows/Preferences/Run-Debug/Launching/LaunchBar/Enable Launch bar
- from Launch bar/project name/Settings - select Toolchain (default)
- set menu/Espressif/Change language : English

Apart from the fact that it builds normally and there are no errors, it quite correctly makes transitions to variable definitions and "Ctrl + mouse click" types (including types with "Unresolved" warnings))
