Re: coreutils: use dummy man when cross build
Source: coreutils
Version: 8.28-1
Severity: normal
Tags: patch
Usertags: rebootstrap
Hi
We also did cross build coreutils and got the same problem that help2man
can't get `--help' info from cross-binaries.
We tried adding an extra step in debian/rules that builds native man
pages first, then force cross build process re-use those man pages.
This way may make build process a bit longer but it can generate the
complete man pages itself.
I attached the patch.
Regards,
Trung
