[opensuse-buildservice] Dependencies: what if some distro have it, some distros don't?
Hi all I have a package that needs a fairly recent version of SCons in order to build. This version is available in most of the newer distros, but seems to be missing in some others, specifically openSUSE 10.2 and Mandriva 2006. There is a SCons package somewhere else in the Build Service and I can link to that if I want. However I am not sure how this work when for example FC6 already has the required version in the 'extras' repostory, versus openSUSE 10.2, which doesn't have it. Is there a way I can specify for the Build Service to use my local package *only when* a satisfactory version is not available in the base repository? Or is this already the default behaviour?

That's probably the wrong approach, instead you should layer the repositories in question on top of the ones containing the SCons package.

Firstly, how would I do that? And what is the implication for my 'home:jdpipe' repository in that case? Does it gain all of the other repository's packages somehow? Or do I need to tell users to add *two* files to their yum.repos.d folder instead of one? And I wonder why in this case it's not better to just selectively build the package for those distros that lack it. Actually: it would be great if one could somehow automatically specify only to build certain packages when the package is not in the source repository, eg a special comment in my spec file: # NotRequiredIf: scons >= 0.96.92 Cheers JP --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org

Via the "Expert" mode in the repository creation dialog.

That's a project, not a repository. The repository search path can be configured individually for every repository in your project.
Does it gain all of the other repository's packages somehow?
No, it just uses the packages for building.
Or do I need to tell users to add *two* files to their yum.repos.d folder instead of one?
I'm afraid this is true for the current installers. If you don't want this, you can use an "aggregate" to copy some binary packages into your repository without the build step. (A link just links the sources, so every linked package needs to be rebuilt.)
And I wonder why in this case it's not better to just selectively build the package for those distros that lack it.
Or aggregate them.

Hmm, I have to think about this a bit.
