Hello!
To be able to add a cross-compilation option to guix-system (see https://lists.gnu.org/archive/html/guix-devel/2019-03/msg00062.html), we need to cross-compile a bunch of guile libraries. Even if guild has a "target" option allowing to cross-compile sources, autotools does not seem to have support for guile cross-compilation. For instance, passing "--host=aarch64-linux-gnu" to configure script doesn't set the "target" argument of guild to the specified triplet. For trivial guile libraries guix has a "guile-build-system" which does the job alright, but I don't think using this build-system for every guile library is a solution. Has anyone already tried to mess with guile.m4 and other stuff in order to cross-compile a guile library via autotools? Thanks, Mathieu
