Trying to build go1.9 with just gcc-go yields [ 4s] ##### Building Go bootstrap tool. [ 4s] cmd/dist [ 4s] go: go.mod file not found in current directory or any parent directory; see 'go help modules' [ 4s] error: Bad exit status from /var/tmp/rpm-tmp.54rZem (%build) for gcc11-go - it works with gcc10-go (thus in current Factory). I'm not sure what this means tho. I've checked adjusted packages into home:rguenther:branches:devel:languages/go1.{9,10} It might mean gcc11-go doesn't work at all - who knows?!
