Thank you for reporting this!

Fixed.
Please sync to latest version of lv_micropython, update submodules and try again.

I have latest (master) and still getting this error.

Hi @Phil_Jepsen !

We now have CI tests to make sure lv_micropython master branch is healthy.
These tests check that the unix, esp32 and stm32 ports are building without errors and even run tests on the unix port.
Currently all tests pass, as you can see on GitHub Actions.

Therefore your problem must be local to your environment.

  • What esp-idf version are you using?
  • Did you remember to update git submodules recursively?
  • Did you try to start over with fresh environment?
