Failed build

[igormoochnick]

Most likely I'm missing a step but, after doing:

bringing all submodules in
idf.py set-target esp32
idf.py build

I get the following error:

/Dev/CNC/WT32-SqLn/components/LovyanGFX/src/lgfx/v1/misc/pixelcopy.cpp: In constructor 'lgfx::v1::pixelcopy_t::pixelcopy_t(const void*, lgfx::v1::color_depth_t, lgfx::v1::color_depth_t, bool, const void*, uint32_t)':

Any suggestions?

Other than setting the target to 'esp32s3', I have no idea.

I had this error gone after i reinstalled the esp idf with the version 5.2

Other than re-installing IDF, you can also try

$ cd components/LovyanGFX
$ git checkout 1.1.5
$ cd ../..

I just switched laptops and ran into the same issue with a fresh IDF install. Using v5.0.2 seems to fix the problem.

However, it is indeed an error in the Lovyan library which is fixed in later releases. I've updatyed the LovyanGFX submodule to 1.1.7
