[Pkg-matrix-maintainers] Bug#962682: nheko FTCBFS: multiple issues

[Helmut Grohne]

Source: nheko
Version: 0.7.1-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: cross-satisfiability ftcbfs

nheko fails to cross build from source. The immediate cause is its
Build-Depends on g++. This dependency is unsatisfiable and needs cross
translation. Unfortunately, cross translation isn't supported in the
archive yet. However, the dependency is implicitly satisfied even in
buster, so it can be safely dropped. Then it runs cmake for the build
architecture. An easy way to pass cross flags to cmake is calling it via
dh_auto_configure The resulting patch makes nheko cross buildable.
Please consider applying it.
