  Welcome to the ffmpeg cross-compile builder-helper script.
  Downloads and builds will be installed to directories within /home/lzy0702/ffmpeg-windows-build-helpers/sandbox
  If this is not ok, then exit now, and cd to the directory where you'd
  like them installed, then run this script again from there.
  NB that once you build your compilers, you can no longer rename/move
  the sandbox directory, since it will have some hard coded paths in there.
  You can, of course, rebuild ffmpeg from within it, etc.

Ovbiously, I have "build-essential" package installed.

you need a LANG=en_US or LANG=C environment

I switched to en_US, and still have the same problem.

nuke sandbox and try with LANG=C again?

nuke sandbox and try with LANG=C again?

unfortunately, same error message.

[lzy0702]

As I tried, it seems the GCC 10.2 in the toolchain does not support 'alderlabke' architecture. GCC 10.2 only supports up to tigerlake. Maybe it's necessary to upgrade the toolchain to most up to date GCC.

Faced the same issue when trying to compile for AMD Zen 3 processors, 10.2 doesn't support Zen 3 processors -march=znver3, unfortunately it only goes up to Zen 2.
