6.7.7 has API bugs. Why not upgrade to 6.8.5-4 which is much better?

Asked by Herbert on 2013-05-06

I've created a Go binding to ImageMagick and found out that the current Ubuntu's version (6.7.7) have some API bugs. I had to build the newer ImageMagick version in /usr/local to create the binding.

Why Ubuntu's version is so old? The last 6.7.7 release was launched 2012-06-28 6.7.7-10.

I was hoping 13.04 got some upgrade on this and nothing :(

What is blocking this upgrade?

Can I help on something? I'm interested in having an updated official package.

Look for libpng17 and libpng16 while configuring PNG support.

Manfred Hampl (m-hampl) said : #2

I suggest you create a bug report requesting that the package be updated in the development release.
As soon as the package is updated to the current release in saucy, a backport to raring can be asked for.

You could speed up the process by creating a PPA with the up-to-date version for raring to confirm the feasibility of the upgrade.

Can you help with this problem?

Provide an answer of your own, or ask Herbert for more information if necessary.
