README does not document ocaml-cairo dependency #151

Open gdt opened 2 years ago

gdt commented 2 years ago

README.md does not list ocaml-cairo as a dependency, but building without results in an error that cairo2 is missing.

(For background, I am the maintainer of unison and I am trying to untangle what seems to be lablgtk3 depending on ocaml-cairo which is documented to depend on lablgtk2.)

Indeed, you're right. We kind of expected everybody to install through opam, which includes the dependency, but we should update the README too.

gdt commented 2 years ago

I use it through pkgsrc, which (as I think all or nearly all other packaging systems do) manages dependencies explicitly, so that there aren't files installed via N different language-specific systems (opam, pip, etc.).

I should have mentioned: cairo2 raises the issue of the other 2 things included from the ocaml-cairo source distribution. I am pretty sure lablgtk does not need them, bit it would be nice if that were clear.

I have just diabled the gtk and pango options in pkgsrc's build of ocaml-cairo.
