Thanks Johnny, So I know it builds on your server (and I could potentially just pull the rrdtool-perl rpm from your buildlogs server.) But I still would feel better if I could build it on my own server. I added the macros from mock.cfg config_opts['macros']['%centos_ver'] = "7" config_opts['macros']['%rhel'] = "7" config_opts['macros']['%el7'] = "1" config_opts['macros']['%redhat'] = "7" config_opts['macros']['%vendor'] = "CentOS" config_opts['macros']['%packager'] = "CentOS BuildSystem < http://bugs.centos.org>" config_opts['macros']['%_vendor'] = "redhat" config_opts['macros']['%_vendor_host'] = "redhat" config_opts['macros']['%_host'] = "x86_64-redhat-linux-gnu" to my ~/.rpmmacros %centos_ver 7 %rhel 7 %el7 1 %redhat 7 %vendor CentOS %packager "CentOS BuildSystem <http://bugs.centos.org>" %_vendor redhat %_vendor_host redhat %_host x86_64-redhat-linux-gnu but the build still fails with the same error on my system. Do you have the rpm macros set on your build server somewhere accessible/viewable? Or can someone else build this on "normal" CentOS 7 box 1000 thanks, Lars On Thu, Jul 31, 2014 at 9:20 AM, <jonny at c <lars.holowko at gmail.com>entos.org> wrote: All our build logs for CentOS 7 are on buildlogs.centos.org ...
