Latest PPC Fedora release

Latest Fedora release for PPC is currently Fedora 12 and can be found from http://download.fedoraproject.org/pub/fedora/linux/releases/12/Fedora/ppc/iso/


We're doing composes of the F-15 packages and create bootable DVD isos. Repositories with the latest packages can be found on our koji hub, the DVD images are currently available in a temporary location. Don't expect to be able to install with these DVD isos yet or with the bootimages from the mash directories, it might or it might not work on your machine due to the new combined initrd which is to large for some PowerPC firmwares. The images are known to work on the new Power7 machines and on a PowerMac G5 with 8Gb RAM. There's a workaround for that, but it requires to have a system with an older RHEL or Fedora installation. If you still want to help out with testing, please report any problems on IRC or in bugzilla (make sure to set the architecture to 'powerpc'). Especially feedback about installations on older hardware such as 32bit PowerMac G4 is appreciated.

Fedora rebuild efforts

There are currently efforts ongoing to recompile all packages and prepare a F-15 release or if we find out that we are too far behind the primary archs to have a F-16 release. This is the current status of the package rebuild: Ppc-statistics.png

Rebuild problems, TODO list

- The most urgent problem at the moment is to get the latest version installable (maybe even with some workarounds for problems) so that the installer and bootloader teams can pick up the work.

- The Haskell Compiler (ghc) is available on PPC64. Jens Petersen & Jiri Skala work on bumping haskell-platform packages for PPC64. Unfortunately upstream don't support GHCi & NGC for PPC64. Therefore following packages aren't available for PPC64:

  • ghc-template-haskel
  • ghc-ForSyDe
  • ghc-QuickCheck
  • ghc-hamlet
  • ghc-parameterized-data
  • ghc-type-level
  • haskell-platform packages.

- yaboot only available on PPC which means we currently need some hacks for 64bit boot images

- Internal compiler error in latest gcc bugzilla #703888

- segemtation fault of alt-ergo.opt during build bugzilla #704236

The PowerPC koji build system

All official Fedora PowerPC packages will be built by the koji build system at the PowerPC koji hub

All non-scratch packages that haven't been deleted by the garbage-collector are available at the package storage, scratch builds can be found for a few days at the scratch repository

Building packages on the PowerPC koji build system

Everyone with a Fedora account can do at least scratch builds of packages on the PowerPC koji build system, package maintainers who can check changes into the git repositories can build updated packages that will later on end up in the distribution.

Doing scratch builds

After running fedora-packager-setup from the fedora-packager rpm

ppc-koji build --scratch dist-f15 yourpkg.src.rpm

These builds will be removed from koji automatically after a while.

'real' builds

'Real' builds will be pulled into the package repositories and into the install images, unless they got replaced by later versions. After running fedora-packager-setup from the fedora-packager rpm

ppc-koji build dist-f15 "$(fedpkg giturl)"

or

fedpkg build --target=dist-f15
(this works only when you have a symlink from ~/.koji/ppc-config to ~/.koji/config)

PPC Shell access for debugging

David Woodhouse (dwmw2) and Josh Boyer (jwboyer) may provide you access to a PPC box for build debugging purposes. Just send them an e-mail with an request and a public SSH key.
