Hi,
I have a question regarding marking
golang-github-danverbraganza-varcaser-dev Multi-Arch: foreign
what's the purpose of it?
I did find an explanation from https://wiki.debian.org/Multiarch/HOWTO:
> If a package is marked 'Multi-Arch: foreign', then it can satisfy dependencies of a package of a different architecture (e.g 'debhelper:amd64' will satisfy a dependency on debhelper for any-architecture package).
Yet, I'm unable to digest that -- e.g., why an amd64 architecture
needs dependencies of a package from amd64?
Helmut's explanation was:
> easygen cannot be cross built from source, because its dependency on
golang-github-danverbraganza-varcaser-dev is not satisfiable.
In general, Architecture: all packages can never satisfy cross
Build-Depends unless marked Multi-Arch: foreign or annotated :native.
I guess I don't understand the concept and implication of Debian's
cross built, as I see that easygen is being cross built without
'Multi-Arch: foreign', yet golang-github-danverbraganza-varcaser-dev
is not, despite having the 'Multi-Arch: foreign' .
https://buildd.debian.org/status/package.php?p=easygen vs.
https://buildd.debian.org/status/package.php?p=golang-github-danverbraganza-varcaser
Please help.
