This library is currently used in SUSE by YaST/zypp. I'm currently trying to make it less SUSE specific like adding support for package coloring and different repo handling, but I'm pretty sure I didn't catch all things where Fedora is different from SUSE. To test things I've written a small application called "solv" that works like a very tiny package manager. It's available via: <a href="http://software.opensuse.org/search?baseproject=Fedora:11&q=libsatsolver-demo" target="_blank">http://software.opensuse.org/search?baseproject=Fedora:11&q=libsatsolver-demo</a> (To get the src rpm search for "libsatsolver") The package contains just a single file, "/usr/bin/solv". It can be run as normal user, but then the transaction can't be commited. Also, the repository metadata caching mechanism needs write access to /var/cache/solv. If it can't write there, it still works but downloads the metadata again every time it is called. So, if you have some spare time, could you give it a try and tell me where it works well/ does stupid things/ doesn't work at all? Thanks, Michael. </blockquote><div> </div></div>BTW, if you want a wider audience for your project, outside the narrow circle of people involved in rpm development :=) for example, so that it can be considered for inclusion in different distributions from OpenSUSE, you should, as usual, publish it as a separate and autonomous project. This is what do yum and smart for example, both in Fedora repository. Regards (aside) in a (perhaps old but not i cannot check now the latest release) RHEL5 release glibc don't have qsort_r (<a href="http://sourceware.org/bugzilla/show_bug.cgi?id=173">http://sourceware.org/bugzilla/show_bug.cgi?id=173</a>) so the code don't compile. <a href="http://sourceware.org/ml/glibc-cvs/2007-q4/msg00436.html">http://sourceware.org/ml/glibc-cvs/2007-q4/msg00436.html</a>
