[Debichem-devel] Bug#983221: chemps2: reduce Build-Depends

[Helmut Grohne]

Source: chemps2
Version: 1.8.9-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: cross-satisfiability

chemps2 cannot be cross built from source, because its sphinx dependency
is not satisfiable. Fortunately, the documentation resides in an
arch:all packages, so sphinx is not actually required in Build-Depends.
It can be moved to B-D-I if the relevant build instructions are skipped
in arch-only builds. Please consider applying the attached patch to make
that happen (post bullseye). Beyond helping cross compilation, this
change reduces the load on buildds.
