Subject: [Buildroot] [PATCH] libpng: add libpng12
Date: Sun, 11 Jan 2015 12:49:25 -0600 [thread overview]
Message-ID: <54B2C5B5.4070703@ou.edu> (raw)
Some programs still link using the legacy -lpng12 version
of libpng for handling PNG (Portable Network Graphics)
images. It is still maintained for security fixes so
make it available.

The png support in freetype uses libpng v1.2 instead of v1.6.
Currently freetype is configured without png support but another
package I am investigating wants it, so here is a patch to enable it.
I copied and modified the files from libpng and do not know if the
arm specific option is needed for v1.2 since I'm only using x86.
