This is a bug. # This partial makefile compiles the png library for use in the Ghostscript # PNG drivers. You can get the source code for this library from: # ftp://swrinde.nde.swri.edu/pub/png/src/ # ftp://ftp.uu.net/graphics/png/src/ # Please see Ghostscript's `Make.htm' file for instructions about how to # unpack these archives. # # When each version of Ghostscript is released, we copy the associated # version of the png library to # ftp://ftp.cs.wisc.edu/ghost/3rdparty/ # for more convenient access. # # The makefile is known to work with the following library versions: # 0.89, 0.90, 0.95, 0.96, 1.0.1, 1.0.2, 1.0.3. # NOTE: the archive for libpng 0.95 may be inconsistent: if you have # compilation problems, use an older version. # Please see Ghostscript's Make.htm file for instructions about how to # unpack these archives. # # The specification for the PNG file format is available from: # http://www.group42.com/png.htm # http://www.w3.org/pub/WWW/TR/WD-png # (Rename directories.)
