Introduction in creating RPM packages

Stuff coveredBasic concept of RPM packaging

How to write a simple SPEC for a simple package

Stuff not coveredStuff from Fedora Packaging Guidelines

Advanced tricks around RPM packaging

Whatever off-topic

Matter of day

OutlineGetting Started

Quick into to RPM

How RPMs are packaged

RPM Packaging BasicsThe toolset

The SPEC file

Writing a SPEC file

Building your package

Getting Started

Creating a RPM package is easyEquivalent to writing a script for automatically compile and install a particular source code package

With some extra rules to follow

Straightforward, write a SPEC, put the source tarball and the SPEC in the correct place, run rpmbuild, wait, fun, profit!.

The ToolsetRPMBuild

Obviously, used for building RPMyum install rpmdevtools fedora-packager

This is the primary tool needed for building RPM.

rpmbuild -ba mypackage.spec

rpmbuild --rebuild mypackage.src.rpm

rpmbuild -ta mypackage.tar.bz2

Exist an Eclipse plug-in called : Fedora Packager

yum install eclipse-fedorapackager

The SPEC fileLook at it as the specification config for a RPM package

Generally consist of several partsHeaders

Source preparation script (%prep)

Build script (%build)

Install script (%install)

Post-installation cleanup script (%clean)

Installed files listing (%files)

SPEC changelog (%changelog)

Writing a SPEC fileGeneral steps

Define the package information

Figure out the dependencies required for building the package and define in the spec

Write the prepare script

Write the build script

Write the install script

Define files included in the package

Building RPM packagesTo create a RPM build tree skeleton

rpmdev-setuptree

This will create a tree in ~/rpmbuild containing:

BUILD – folder for temporary build files

BUILDROOT – folder for temporary install files

RPMS – generated RPMs are saved here

SOURCES – where you should put your source tarballs

SPECS – where you should pun your specfile

Building RPM packagesSave the specfile in the SPEC folder

Copy the source tarballs to the SOURCES folder

Chdir to the SPEC folder, and build!!!rpmbuild -ba yourspecfile.spec

The build process will run,Source RPM will be saved in SRPMS folder, and binary RPM will be saved in RPMS folder.

Make the stepGrab some softwares which are not packaged in Fedora Repository, package them, and submit for review on BugzillaStart writing your RPM package!
