We have just merged support for GCC 11 into IDF internally. It might take a few days for the code to get synced to Github, as currently there are some failing tests in our CI pipeline, we'll have to fix them first.

Hi @wuyuanyi135,
esp2022-r1 toolchain is not compatible with IDF v4.4. To support GCC 11, we had to make multiple significant changes, including breaking ones. They will be released as part of IDF v5.0.
v4.4 release branch will continue to use the toolchain based on GCC 8.
(Generally though, trying a different toolchain involves several steps: 1) Download the new toolchain release; 2) Unpack it into a directory of your choice; 3) prepend the absolute path of the resulting bin
subdirectory to your PATH variable using set
or export
command; 4) do idf.py fullclean
; 5) build the project again.)

@igrr Thanks for your detailed instructions. Does the current IDF v5.0 branch already support GCC11?
