Glenn Randers-Pehrson5cded0b2001-11-07 07:10:08 -0600[diff] [blame^]2Installing libpng version 1.2.1beta4 - November 7, 2001
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]3
4Before installing libpng, you must first install zlib. zlib
5can usually be found wherever you got libpng. zlib can be
6placed in another directory, at the same level as libpng.
7Note that your system might already have a preinstalled
Glenn Randers-Pehrson5c6aeb21998-12-29 11:47:59 -0600[diff] [blame]8zlib, but you will still need to have access to the
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]9zlib.h and zconf.h include files that correspond to the
10version of zlib that's installed.
11
12You can rename the directories that you downloaded (they
Glenn Randers-Pehrson5cded0b2001-11-07 07:10:08 -0600[diff] [blame^]13might be called "libpng-1.2.1beta4" or "lpng109" and "zlib-1.1.3"
Glenn Randers-Pehrson5c6aeb21998-12-29 11:47:59 -0600[diff] [blame]14or "zlib113") so that you have directories called "zlib" and "libpng".

Glenn Randers-Pehrsondb66d442000-06-23 21:38:16 -0500[diff] [blame]51If you are building libpng with MSVC, you can enter the libpng\msvc directory
Glenn Randers-Pehrsonb1828932001-06-23 08:03:17 -0500[diff] [blame]52and follow the instructions in msvc\README.txt.
53
54You can build libpng for WindowsCE by entering the downloading and installing
55the libpng\wince directory as instructed in the projects\wince.txt file, and
56then following the instructions in the README* files. Similarly, you can
57build libpng for Netware as instructed in projects\netware.txt.

116Copy the file (or files) that you need from the
117scripts directory into this directory, for example
118
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]119 MSDOS example: copy scripts\makefile.msc makefile
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]120 UNIX example: cp scripts/makefile.std makefile
121
122Read the makefile to see if you need to change any source or
123target directories to match your preferences.
124
125Then read pngconf.h to see if you want to make any configuration
126changes.
127
128Then just run "make test" which will create the libpng library in
129this directory and run a quick test that reads the "pngtest.png"
130file and writes a "pngout.png" file that should be identical to it.
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]131Look for "9782 zero samples" in the output of the test. For more
132confidence, you can run another test by typing "pngtest pngnow.png"
Glenn Randers-Pehrson6d8f3b01999-10-23 08:39:18 -0500[diff] [blame]133and looking for "289 zero samples" in the output. Also, you can
134run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare
135your output with the result shown in contrib/pngsuite/README.
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]136
137Most of the makefiles will allow you to run "make install" to
138put the library in its final resting place (if you want to
139do that, run "make install" in the zlib directory first if necessary).
