Source: lapack
Version: 3.12.0-3
Tags: patch
User: debian-cr...@lists.debian.org
Usertags: cross-satisfiability
lapack cannot be cross built from source, because its dependency on
gfortran is not satsifiable and its dependency on the host architecture
python3 fails to install. It turns out that python3 is only used for
testing, so we may simply annotate it <!nocheck>. The gfortran
dependency was an unsolved issue as it needs "toolchain dependency cross
translation", but this has been solved earlier this year and we can now
translate it to gfortran-for-host. Beware that gfortran-for-host does
not provide a "gfortran" binary and requires the consumer to always call
it architecture-qualified. This is what lapack already does by setting
FC, but the use of gfortran-for-host turns this setting into a
requirement. I hope this is ok. Also note that lapack will not actually
cross build until gcc bug #1086679 is solved. I'm attaching a patch for
your convenience.
