Both are available in Fedora 19, so any of them can be rebuilt and have its BuildRequires satisfied. The question is how did it get built the first time. And John already responded to that in the part quoted above. Note that circular build dependencies are in fact quite common, for example in Perl modules. What happens is that you'll bootstrap it by first building A, without the BuildRequires on B (for example having B present in the buildroot is only needed for an optional feature in A, or for the unit tests,...). Then you build B, with its build dependency on A. And finally you rebuild A, this time with the build dependency on B. -- Mathieu -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
