Cross-build go-1.22 for ppc64le from 386.
- Prepare a go environment of 386 isa
- Checkout a source directory of go1.22.2
- Run
cd src
bash make.bash
with environments
GOARCH: ppc64le
GOOS: linux
GOHOSTARCH: 386
CGO_ENABLED: 0
The was run in a test of freedesktop-sdk-binary-seed, full log is available https://gitlab.com/freedesktop-sdk/freedesktop-sdk-binary-seed/-/jobs/6679102887
I also tested some other combinations:
- go-1.21 386 bootstraps go-1.21 ppc64le: good
- go-1.21 386 bootstraps go-1.22 amd64, arm64, 386: good
- go-1.22 386 bootstraps go-1.22 ppc64le: bad
What did you see happen?
The build failed with errror log:
+ sh -c -e 'cd src
bash make.bash

What did you expect to see?
The build succeeds since Go 1.22 was announced boostrappable from Go 1.20+.
