A little update. After I set some compiler options in cmake file it shows:

Hi, thanks for reporting the issue, could you try the below patch:

Hi, thx for the quick reply! I tried your patch.

For the example from WAMR repo it still complains.

Hi Thank you! It works but new issue occurs as below:

Hi, depth should have been set in L11433 read_leb_uint32(p, p_end, depth), not sure why the compiler reports the warning. Please initialize it with 0:

Hi, yeah its weird. And now it shows:

@TAOFOR4 Could you please try #3224?

@TAOFOR4 Could you please try #3224?

Hi, it works well now :) Thx for help! Btw, will WAMR add support for ESP C6? I noticed that right now it only supports ESP32 and ESP32 C3. Thank you!

Welcome, currently no plan to support ESP C6 yet. Maybe you can have a try and help commit the code? It would be greatly appreciated.
