Hi,
I am working on some CloudStack/Xen related stuff that happens to depend on OCaml. I've already added a bunch of dependencies to Virtualization:Cloud:CloudStack:Testing but am geeting stuck with a problem that I do not know how to resolve, and help is much appreciated.
The current package I am trying to build is ocaml-ocamlnet (not submitted to OBS yet). The code has an option to build gtk2 bindings and I'd like to enable this. Enabling GTK2 requires lablgtk2 which I added as a BuildRequires to my spec file. I get the following error when I try to build for 12.1:
buildinfo is broken... it says: unresolvable: nothing provides ocaml(runtime) = 3.12.0 needed by lablgtk2
The ocaml package in the project I am working on (Virtualization:Cloud:CloudStack:Testing) is linked to devel:languages:misc which is up to 3.12.1. When I look at https://build.opensuse.org/package/view_file?file=lablgtk2.spec&package= lablgtk2&project=openSUSE%3A12.1&rev=74c0704a0eaf6d064efe12d5424dbfaf, the spec file for lablgtk2 there is no explicit version requirement for ocaml, i.e. a Requires: ocaml = X.Y.Z, yet the package obviously requires this.
That are automatically generated dependencies similar to the linking dependencies generated for normal binaries.
I would prefer not build a different ocaml version than we have in the project. Obviously there is something going on that I do not understand.
Since ocaml packages depend on the exact upstream version they were built against, if you want to use your own ocaml (i.e. a different upstream version than the project you're building against) you will need to rebuild all your ocaml dependencies against that ocaml. (That's not a ocaml-unique problem btw, e.g. Perl packages have the same behavior) So you should probably consider whether you really need your own ocaml.
