I tried to add ruby to the built dependencies of a package of mine and
the following message on ArchLinux in OBS (during "osc build" on my dev
machine): unresolvable: nothing provides libyaml needed by ruby

Can someone import this package as well so we can build ruby packages?

libyaml is available from the Community repo in Arch, not Core or
Extra (
which are what we have in the Build Service.
When building for Arch in my home project, I just made a new package
(called 'libyaml' in your case), copied the PKGBUILD from
es/ libyaml and set it to not publish and to only build for Arch. You'll
also have to manually download the source tarball and edit the PKGBUILD
to reference the local file rather than the remote one.
For me this then satisfied the dependency. I did however have to go a
few levels deep and ended up with all the packages in

As an aside, this would all be easier if the Arch build machinery
could automatically look in the PKGBUILD, download the tarball
mentioned in 'source' and silently tweak the 'source' line to refer to
the local file.

Hope this helps,

ok, I assumed that something that is in Core (ruby in my case) only has
dependencies to Core packages (libyaml) and assumed it was just missing

well, apparently, I was wrong and need to include it like you did - let's
hope it does not go that deep...

You're right that it's weird that a package in Core can have a
dependency on a package in Community. I'm not sure how that's supposed
to work but I've never really used Arch.

libyaml only seems to be a pure c library so it should be a simply
package to build with no dependencies.


indeed, it was - the site you gave me also stated "no dependencies" so good
for me

(maybe it's an optional dependency - although since it's a lib, I don't think
so - anyway, that's for the Arch guys to figure out / solve
