If you have built and installed any of the previous packages here, it has been reworked and I preferred to not carry updates logic for now, so, to update to the new prototype packaging, I suggest: # rpm -e coin-or [[ if you built/installed the monolithic one ]] or: # rpm -e `rpm -qa | grep coinor-` [[ if you built/installed the per project ones ]] [Suggested] Order of build/install is: coin-or-Sample # already in Fedora coin-or-CoinUtils # already in Fedora coin-or-Osi # already in Fedora coin-or-Clp # already in Fedora coin-or-Cgl # already in Fedora coin-or-Alps # already in Fedora coin-or-Bcps # already in Fedora coin-or-Vol # already in Fedora coin-or-Bcp # already in Fedora coin-or-Blis # already in Fedora coin-or-Cbc # already in Fedora coin-or-DyLP # already in Fedora coin-or-CoinMP # already in Fedora coin-or-cppad # provided by the cppad package coin-or-Dip # already in Fedora coin-or-FlopC++ # already in Fedora coin-or-Ipopt # already in Fedora coin-or-Bonmin # already in Fedora coin-or-Couenne # already in Fedora coin-or-SYMPHONY # already in Fedora coin-or-OS
