Ghostscript 9.02 fails to build on 10.7 #6381

PacifistRiot opened this Issue · 14 comments

Im assuming 10.7 has an updated version of libpng and Ghostscript 9.02 build fails on libpng 1.5.

Here is a patch to fix the issue with gdevpng.c and allows the build to finish:


Thanks for this.

brew edit ghostscript

Then add:

class Ghostscript < Formula
    def patches
        { :p0 => '' }

Incase anyone else has the same issue.


Is this safe to apply against libpng 1.2 as well, or do we need to if the application of this patch?


Made a patch that compiles against 1.2 and 1.5
Also it makes ghostscript use system freetype and expat and lcms, jasper and libtiff from homebrew
Pull from
git:// fix_ghostscript_png

Not sure about 10.6 freetype so ghostscript uses bundled version instead of system on 10.6


That worked like a charm!!... Thanks guys!


Awesome! This seemed to solve my issues I had installing ghostscript on Lion. Thx


This also fixed my problem doing a make install on Lion. Thanks a great deal!


Thanks again for being quick on patches .... running faster than a lion !


When is this patch going to be included?
