Ensure your computer has all the required software installed and in working condition (excluding KOffice of course). You can find the system requirements by following this link: System Requirements.

Download the KOffice source file into a temporary folder.

If the filename ends in .src.rpm (Red Hat® Package Management file), the source code for KOffice can be installed with:

$ rpm-U filename

If the filename ends in .src.tar.gz or .src.tgz (a tarball file), the source code for KOffice can be installed with:

$ tar -xzvf filename

The source code for KOffice should now be installed on your system.
