Re: [Caml-list] Speeding up compilation

[Pietro Abate <Pietro.Abate@pps.univ-paris-diderot.fr>]

For quite a while I've simply used 
pp(camlp4o.opt -I_build Camlp4MacroParser.cmxs)
in my _tag file and make sure that the plugin
Camlp4MacroParser.cmxs was either available on that I made
available in the _build directory.

In my makefile I have a rule I use to compile the plugin
before calling ocamlbuild. If you use a configure script
you can change accordingly these elements to use camlp4o instead
of camlp4o.opt .

camlp4cmxs:
  mkdir -p _build
  ocamlopt -shared $(shell ocamlc -where)/camlp4/Camlp4Parsers/Camlp4MacroParser.cmx -o _build/Camlp4MacroParser.cmxs
