I am using Eclipse CDT 03-2021 with the ESP-IDF Plugin. The plugin does not seem compatible with 06-2021 but the described behaviour is the same. This seems to be a common problem.

Switching from run to debug configuration or vice-verse results in unresolved includes even though it will build with no errors, suggesting the indexer is not in synch with the source. Reindexing, "clean", etc., does not help. Usually a change in configuration immediately results in index issues but if it does not a re-index or build all always does.

Switching back does not fix the indexer. I.e. if you start Eclipse with the run config, switch to debug, then back to run the indexer still fails.

If debug works and I change to run, I get the same problem. I have to switch configurations because of an unfixed bug in the OpenOCD-ESP. Because of the indexer issue I have to

1) Switch to Run config to program the device
2) Close Eclipse
3) Open Eclipse and start the debug session.

This is tedious.

Below is a summary of the log files of a failing and working index

Note that the working index has an Include Search Path (option -I). I cannot find where to set the Include Search Path option for the indexer. In prior projects when I had unresolved includes (i.e. compile failures) there was an option for "Include Paths" but that is not present in the project or window properties, likely because this is a cmake project.

In CDT as shipped, run/debug configurations are used to launch executables.
By this I mean the configurations accessed through
Run --> Run configurations and
Run --> Debug configurations
They are unique by Name.
A run launch configuration with Name==X is the same as a debug launch configuration with Name==X
The only thing that differs between run/debug configurations are the dialogs for changing them.

Are these the Run/Debug configurations you are referring to?
If so, they have nothing to do with the Indexer.
But then, you are using a third party add-on to CDT.
The designers of that would be more likely to help you.
According to the ESP-IDF Programming Guide at
https://docs.espressif.com/projects/esp-idf/en/latest/esp32/resources.html
there is a forum for addressing issues with ESP-IDF at https://esp32.com/
and there is a list of issues at https://github.com/espressif/esp-idf/issues

You might get an answer here, though,
but you should post the exact steps leading to your problem.
It would also be helpful if you could recreate the issue with a very small project.
Preferably one that doesn't depend on plugins.

Thanks for the reply.

There are a number of posts elsewhere where people have complained that Eclipse projects derived from cmake compile but show unresolved includes. These are not ESP-32 related.

I'll try raise the issue with the ESP-32 forum but in general they are very short on solutions. I have several actual issues raised there, including basic things like "following the instructions to build does not work" are there is no reply.

I was hopeful that since the indexer is an Eclipse component and the problem arises from a missing option to the indexer I might get help here.

I have the same problem. I am also using the Espressif's esp-idf tool chain.

Before I switched to debug mode I had no errors from the Indexer. I could click on a #define 'd constant and I would be taken to where it was declared.

Nothing worked after I switched to debugging the project. No real point using an IDE when most of the functionality is gone.

They have fixed it (I am working on other software to talk to the ESP32 at the moment).

Failing that, a fix is to delete the project build directory and re-build the project. This is only needed when you switch between debug and run configurations, which I don't do that often since I am either working on the code (debugging) or finished (build). There is some overhead for the debug version but it is not too bad.
