When emerging docker on arm64 arch it fails with: > cgo: C compiler "x86_64-pc-linux-gnu-gcc" not found: exec: "x86_64-pc-linux-gnu-gcc": executable file not found in $PATH Issue is reproduced in both native env (RPi board) as well as in chroot-ed qemu env. If I cross-compile it on amd64 and then install on arm64 from binpkg then I got: > -bash: /usr/bin/docker: cannot execute binary file: Exec format error Reproducible: Always Steps to Reproduce: 1.

No idea off the top of my head. Built fine here on arm64. Will need gyakovlev. Can you share "env"?

looks like your go is mis-behaving and somehow enters cross mode. but ofc it fails in CGO because no compiler available. what version of dev-lang/go? is it from ::gentoo repo? please send output of the following commands: go env go version

yeah as you see CC="x86_64-pc-linux-gnu-gcc" somehow made it into go. rebuild it without cross or distcc involved. but docker is certainly fine on arm64 if go compiler does not do that =) good luck.
you should be able to override it with go env -w "CC=aarch64-unknown-linux-gnu-gcc" but only for user that runs it. it writes own config to $HOME/.config/go/env but since this is happening for you in portage too it indicates that wrong default value got in and was hardcoded. it does react on changing CC from environment. CC=fake go env CC fake does not look like it gets overridden wrongly by portage environment though, as otherwise it would not show up for you running go as root. so everything points to binary so far.
Indeed. I had broken go. It was installed from binary which was cross-compiled in x86_64. Re-emerged go natively on arm64 and now docker build works fine. Thanks a lot for helping! Bug can be closed.
great to hear, you are welcome.
