RepoForge

Quick Start build system

You want to spin out some fancy RepoForge action yourself. Test rebuilding SPEC files before asking for a pull request perhaps. Here is a quick start guide with the possible commands you might run:

• Spin out a new RHEL/CentOS machine

  KVM is your friend if you do not have a spare physical box.

• Software development tools

    yum groupinstall "Development Tools"
    yum install git
  

• Setup mock (available at RepoForge) and use RepoForge mock configuration to build packages

    yum install mock
  

• Create a build user

    useradd -G mock repoforge
    sudo -u repoforge -i
  

• Checkout the RepoForge RPMs repository (or fork our repo, & checkout your own fork - especially if you plan to submit patches back to us)

    git clone git://github.com/repoforge/rpms.git
  

• Setup a build environment

    mkdir -p ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
    mkdir -p ~/rpmbuild/RPMS/{i386,i486,i586,i686,noarch,athlon}
  

• Build an RPM for your platform

    rpmbuild -bs file.spec
    mock -r <configfile> rebuild package-1.2-3.src.rpm
  

• To build an RPM for an older platform (EL5 package on an EL6 machine):

    mkdir ~/bin
    vi ~/bin/rpmbuild-old
  

• Paste the following contents

    #!/bin/bash
    rpmbuild \
        --define "_source_filedigest_algorithm 1" \
        --define "_binary_filedigest_algorithm 1" \
        --define "_binary_payload w9.gzdio" \
        --define="dist .el5" \
        --define="el5 1" \
        $*
  

• Make the file executable

    chmod +x ~/bin/rpmbuild-old
  

• Now build for EL5

    rpmbuild-old -bs file.spec
  

For those serious about doing a good job - build and test at least on RHEL4, RHEL5 and RHEL6 by specifying correct config files to mock builder
