Target triplet : s390x-alpine-linux-musl
CARCH : s390x (but for linux-headers, it is s390)

Fortunately, I have successfully run crossbuild-bootstrap targeting s390x, but I need to remove paxmark lines in gcc's APKBUILD as it returns an unknown error (creat-cross runs just fine). AFAIK, it is about security concerns, not system's functionality, so for now I guess it is okay. What do you think?

When I try either to (1) install newly cross-built packages into the sysroot-s390x-alpine-linux-musl/ in the build machine or (2) install Alpine in a chroot in the target device using packages from packages-s390x-alpine-linux-musl/main/s390x/ , they both generate following error: Any chance this thing comes from removing paxmark ? I try to pass --verbose to apk-build but cannot see any change. How did you manage to bootstrap on the real target device?

I am using it now.

Hum.. That looks quite complicated. Will definitely come back to this afterwards.
