[FFE] Please backport jerasure and lib-gf-complete from from Ubuntu 14.10 to 14.04 LTS

[Tushar Gohad]

This is a feature freeze exception request. Jerasure and lib-gf-complete is strategically important for Swift, a component of OpenStack. Thank you for considering this fairly simple library for a backport to Trusty (14.04.x).

Hi,

I have just uploaded version 1.0 to Sid. Best would be to use that one rather than the 0.9.10.

Cheers.

Hi Thomas,

The 0.9.10 vs 1.0 comment applies to https://bugs.launchpad.net/ubuntu/+bug/1428377, perhaps? :)

Thanks a lot

Hi Scott, this is also a request related to the liberasurecode update. Jerasure and gf-complete backport to trusty should be very straightforward. Many thanks!

Please test the packages on trusty and indicate that they build/install/run.

Hi Scott, logs above. I jumbled up gf-complete build and install steps - that was a copy-paste error.. Everything was built/installed/tested from the Utopic package sources.
