Fedora Project Overview

FedoraProject

We believe we should use and dis-tribute the software and content wepromote to accomplish our mission ofadvancing free software. We providefree alternatives to proprietary codeand content to make Fedora com-

pletely free and redistributable for everyone. That way,anyone can use any of our work for their own purposes,without legal hassles, to further spread free software.

We believe success comes from astrong community, made of peoplefrom around the world, working to-gether. There’s a place in Fedorafor anyone who supports our valuesand wants to help. By collaborating

with each other openly and transparently, and with astrong, supportive partnership with our sponsors, wecan achieve great things.

We believe the hard work of creatingnew technical features makes free soft-ware more powerful, flexible, and use-ful for millions of people. We don’tmind shaking up the status quo, whenit means we can more effectively move

free software forward. And we do it by collaboratingdirectly with the many software communities whosework is distributed by Fedora. That way everyone ben-efits, regardless of whether they use Fedora or not.

We believe in the power of innovationand showing off new work in our re-leases. Since we release twice a year,you never have to wait long to seethe latest and greatest software, whilethere are other Linux products derived

from Fedora you can use for long-term stability. Wealways keep Fedora moving forward so that you cansee the future first.

Multilib support

To make you package according with Fedora packaging guidelines:

I Add option to build shared libraries

I Add ”with directories;” to the gpr use clauses and use ”forLibrary Dir use Directories.LibDir & ”name””

I OR add library dir/include dir options to configure/makefileoptions
