1.) it is perfectly valid to check package version in a spec calling rpm -q $PACKAGE - Rudi pointed it makes more sense to do that, that missusing %suse_version macro.

I still think it might be a good idea to give Tumbleweed a valid rolling version number like 1225 (1220 < Tumbleweed < Factory = 1230) in /usr/lib/rpm/suse_macros. or just add a new macro like sles.

But since it's not possible (seems), we can use specific package version to do the trick.

eg: xulrunner-devel is not available in <=1210. and Tumbleweed is the only one have 14.0.1 version. (12.2 is 16.0.1 and Factory is 16.0.2)

so:

%if 0%{?suse_version} >= 1220 %if 0%{?xulrunner_version} < 15 // Now you're in Tumbleweed env %endif %endif

the shortcoming is if Tumbleweed updates this package, we need to find new unique package. or we can submit a fake package into Tumbleweed to do the job solely.

A suse_version number only really makes sense for stable releases (that is the version number corresponds to a mostly static set of packages), for Tumbleweed and Factory they do not have much meaning.

PS: Guido, is "s|\\..*$||" regression? I asked around on gtalk, but no one knows such regex style...can you explain it a little bit?

Not sure what you mean, it's just a BRE, the double backslash is needed there because rpmbuild also interprets backslashes. -- Guido Berhoerster -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-packaging+owner@opensuse.org
