-
How to install:
$ opam switch 4.00.1
$ opam repo add win https://github.com/vouillon/opam-windows-repository.git
$ opam install win32-ocaml win64-ocaml win64-lablgtk win64-ssl [...]

Important files:
- OCaml virtual machines for Windows (bytecode mode):
~/.opam/4.00.1/{i686,x86_64}-w64-mingw32/bin/ocamlrun.exe
- Gtk dlls needed at execution time:
~/.opam/4.00.1/{i686,x86_64}-w64-mingw32/lib/gtk/bin/*.dll

Issues:
- To cross-compile i686 opam packages on x86_64 machines, need the glibc.i686 system package
- On old fedora versions (< 17), the C cross-compiler for i686 was named
i686-pc-mingw32-gcc
and noti686-w64-mingw32-gcc
. Please run someln -sf
commands to fix it before installing ocaml cross-compilers
