RPM dev

initial setup

• install packages: rpmdevtools yum-utils
• run rpmdev-setuptree to create ~/rpmbuild hierarchy and .rpmmacros settings

obtaining/unpacking source and preparing build env

• Find the source RPM either in the fedora archives or run yumdownloader --source <package>
• install build-dependencies: sudo yum-builddep foo.src.rpm
• unpack the sources: rpm -Uvh foo.src.rpm

unpacking sources

• only if you want to generate new patches or whatever: cd ~/SPECS; rpmbuild -bp --target=`uname -m` foo.spec

building

• cd ~/SPECS; rpmbuild -bb --target=`uname -m foo.spec
• output is in ~/RPMS/<arch>
