Environment

Ubuntu 22.04 LTS with these packages:

  • git
  • autoconf
  • make
  • cmake
  • flex
  • texinfo
  • help2man
  • gawk
  • libtool
  • libtool-bin
  • bison
  • libncurses5-dev
  • libstdc++-10-dev
  • libstdc++-10-dev-amd64-cross

Known Issues

  1. EXPERIMENTAL_FEATURES is on
  2. gcc can be successfully built (with link errors) in esp32s3 configuration

Besides that, Linking Error does not mean gcc (and build tools) were not compiled for esp32
