[Caml-list] Passing configuration options to opam

[Caml-list] Passing configuration options to opam

[Christoph Höger]

Dear all,

I want to pass a ./configure switch to a package installed via opam. Is
that possible?

In particular, I want to install ocaml-lua with the --enable-luajit
option set.

thanks for any advice,

Christoph

You can do `opam pin edit ocaml-lua` and change the build instructions to your wishes. But best would be to upstream luajit discovery.  

Best,

Note that you will first need to pin to a specific version using e.g. `opam pin add ocaml-lua 1.4`

[not anymore in opam 2.0, but it's not out yet]

Hi Christoph,

Since ocaml-lua is using oasis build system underneath the hood it is
possible to control configuration parameters via environment variables. Any
variable, if not set
explicitly by a command line, will be looked up in the environment.  In
your case enabling `luajit` should be as simple as:

     luajit=true opam install ocaml-lua

Regards,
Ivan
