Re: OCaml cross-compilers (was: Bug#294445: ocaml-source: configure script is not executable)
Bringing the conversation to debian-ocaml-maint list as other may have some
input on this, hope this is ok.

Well, the .deb will have the cross compiler and libraries. It is not all that
easy to organize like that, but my idea is to create a bunch of ocaml-cross
packages (single packages, no real need to over split it, at least at start).

yep. I would like a i386-windows-ocamlopt even. I would have turned it the
other way around. You don't need a ocamlrun and stuff if you produce static
items, and if you use ocamlopt. Also, i would put somewhere in the
/usr/lib/ocaml/cross/powerpc-linux/3.08 or whatever, and have some scripts
which generate the needed package, dir, tarball or whatever for the target
system.

Ok, adding you now, make sure it is a branch of ocaml or something such.
Added even.
