Problems while compiling the project Hello_World

[ESP_Sprite]

The errors you mention all sound like IDE issues. Have you actually tried compiling the project? For the first run, CMake resolves a bunch of dependencies etc, without that IDEs are generally incapable of finding everything.

Using ESP-IDF, I created a new project based on the Hello_World example project.
I gave it a name different from "Hello_World".

I copied the hello_world program from the ESP-IDF v5.0 examples folder as-is without modifying it. It includers the esp_chip_info.h header and it built fine, from scratch. So there's something about your modification of the project that is leading to the error for some reason.

As I said above, the example code DOES build and run properly - both from the command line and in the IDE. The issue is that the Espressif-IDE can not resolve the CHIP_FEATURE macros in the IDE. They are there and properly defined but the IDE underlines them as errors and says that they are not defined.

The issue is with the IDE not knowing the CHIP_FEATURE_* definitions even though they are found by the build system. The include files that define them are right there in the source - how do we get the Espressif-IDE to find the definitions and realize that they are not undefined errors?

Is the IDE syntax checker not processing all of the include files?

Here is a picture of what I mean showing the red underlines:

Do you see them in Espressif-IDE when you load the program? If not, what's different about our configurations?

The Eclipse plugin also sometimes has issues with the visual symbol reference checker (the so called "indexer"). You can double check that all of the Espressif component path settings are correct in the setup. Also, performing a reindex will sometimes resolve it. It can be difficult to resolve in some cases, but if you can build fine, then it's only a visual issue. This problem comes and goes on my Eclipse plugin setup.

I experienced as well that after rebuilding the index an eclipse restart solves the issue in my case.

I have reindexed and it had no effect for me. I'm still playing with this and tried creating a parser log and here are the parts at the end detailing the errors. The fact that it says esp_chip_info.h is not indexed would seem to be the problem, but WHY is it not indexed??? I checked the permissions and ownership of the file and they are fine. The file is intact and correct - otherwise, I wouldn't be able to successfully build with idf.py and Espressif-IDE.

Code: Select all

Unresolved includes (from headers in index):

I have exactly the same problem with the same 3 semantic errors.

Waiting for explanation how to fix it.

+1, different project, same problem.

+1, I have the same problem also. Have tried the indexer rebuild. Same!
