Undefined references to some functions and variables in be_exec.c and be_module.c

[HauNguyen2002]

Hello everyone, I've had no experiences with Berry script yet and trying to integrate it to a project with a ESP32.

After building the cmake, I've already obtains some files in generate and build folder. Then when I build the whole project, some errors appear at the linking stage. I realized some functions and variables are undefined and i don't see their definitions anywhere in the repo.

Please let me know if i lack any step or need extra coding before building the project.

These are the errors:

Here is the berry_config.h that I get somewhere on the internet. (I have to make a text file to upload to this discussion, it's a header file in my project)
berry_config.txt

Why don't you use Tasmota for the ESP32? Tasmota has Berry on board…

[HauNguyen2002]

Well, I'm trying something simpler than Tasmota, I wanna see how the script alone works on the board without further features.

If you want to go the hard way, please read: https://berry.readthedocs.io/en/latest/source/en/Appendix-C.html

You need to implement all those functions with the appropriate implementation for your board in berry_port.c.

Oh thanks, I can see the requirements now.

Some objects files are located in default. You have to link against them.
