libpng
« on: October 17, 2013, 10:23:25 pm »
I am having an issue with a gimp plugin called gmic_gimp. All my good stuff depends on this plugin. The version libpng15 seems to be an issue not just in VL.

Reference:
http://gimpchat.com/viewtopic.php?f=28&t=8584

looking up libpng, it apears that we have an older version of this. The current release of libpng is 1.6.6, and we are at 1.5.12.

Can I get one of the packagers to build the most current version of libpng 1.6.6 ?

  I will be happy to test it out and let you know if it solves my issue (if it doesn't I'm doomed with having to roll back to an older version).

Thanks,
           Masta

7.0 or 7.1?

Ok...i build libpng-1.6.6 for 7.1 and send it to your gmail...but i bet it will cause problem with other programs that need libpng15...

Yes it will, i build it some months ago 'cause is a dependency for the last mupen64plus, but then at reboot windows decorations and icons where not drawn anymore, maybe it was because i did something wrong. But if i remember well i barely edited the slackbuild of the libpng package already installed by default.

The problem is the library naming...libpng-1.6.x use libpng16.so while libpng-1.5.x use libpng15.so

Wouldn't it work with a symlink?

Code: [Select]
# ln -s /usr/lib/libpng16.so /usr/lib/libpng12.so

No, I have tried the symlink, and it doesn't work. It DID however, break some other symlinks :( .

As far as I know of, the only thing depending on this version of libpng1.2 is the gmic_gimp plug-in. It also needs libfftw, libfftw_threads. I am not in contact with GREYC's and do not know if they're working on updates to suit the newer versions of libpng.
