Comments? Hey, yes - when we initially create the packages we actually already discussed how to achieve this. I'd favor the second (meta-package) approach, nothing should go wrong if all three are installed. I'd go even further and create an opencl package (or group?) to install all kind of opencl packages, i.e. clinfo is a good thing to start with. - fabian > Regards, > Dominik > > [1] http://pkgs.fedoraproject.org/cgit/gromacs.git/commit/?id=dbabc099d66902daa094478024a8a331822b78bc > -- > Fedora http://fedoraproject.org/wiki/User:Rathann > RPMFusion http://rpmfusion.org > "Faith manages." > -- Delenn to Lennier in Babylon 5:"Confessions and Lamentations" -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
