From: Dave dave.mehler@gmail.com Subject: [CentOS] building CentOS rpms? To: centos@centos.org Date: Friday, August 14, 2009, 5:31 PM Hello, I'd like to get in to rpm building and am looking for a CentOS specific document if any to get me going? I want to repackage an existing rpm and give it different runtime options so it'll work on a server, and make an rpm at least one probably more, and then submit them to the rpmforge repo.
The rpmforge repo is independent (but much loved) from Centos. It has its own rules and mailing lists. http://lists.rpmforge.net/
To get started you need a small toolset called rpmdevtools (found at Epel). (usage): To make a buildroot in your home folder, rpmdev-setuptree Create RPM build tree within user's home directory
The bible for building rpm packages was written by Ed Bailey http://www.rpm.org/max-rpm/
Fedora has stellar docs for rpm building, compatible with Centos https://fedoraproject.org/wiki/Packaging/Guidelines
To modify an SRPM, you need to extract the source to your buildroot first. If you want to change default values in a config file, then rebuild the rpm, you can use rpmbuild.
