Version: 0.3.29+ds-3
Tags: patch
User: [email protected]
Usertags: cross-satisfiability ftcbfs
openblas fails to cross build from source for several reasons. The
immediate problem is that gfortran as a build dependency cannot be
installed. "gfortran" refers to the native compiler for the host
architecture and if it were installable it could not be run. Instead,
openblas should build depend on "gfortran-for-host". Doing so comes with
a twist though. You cannot just run "gfortran" then. A triplet-prefixed
variant must be used (even for native builds). To comply with this
limitation, a suitable FC variable needs to be passed to the build
system. A suitable value can be obtained from dpkg's buildtools.mk.
While at it, I suggest also setting CC to make the build system honour
the builders choice. For actually cross compiling, the build system
needs to be told via CROSS=1 and it also needs a HOSTCC. And with that
in place, cross building openblas seems to just work. I'm attaching a
patch meant for forky for your convenience.
