(** * Plugin for building Coq via Ocamlbuild *)
open Ocamlbuild_plugin
open Ocamlbuild_pack
open Printf
open Scanf
(** WARNING !! this is preliminary stuff. It should allows you to
build coq and its libraries if everything goes right.
Support for all the build rules and configuration options
is progressively added. Tested only on linux + ocaml 3.11 +
local + natdynlink for now.
Usage:
./configure -local -opt
./build (which launches ocamlbuild coq.otarget)
Then you can (hopefully) launch bin/coqtop, bin/coqide and so on.
Apart from the links in bin, every created files are in _build.
A "./build clean" should give you back a clean source tree
*)
(** F.A.Q about ocamlbuild:
* P / Px ?
Same, except that the second can be use to signal the main target
of a rule, in order to get a nicer log (otherwise the full command
is used as target name)
