Glenn Randers-Pehrson0cc2f952002-10-03 06:32:37 -0500[diff] [blame^]2Installing libpng version 1.2.5 - October 3, 2002
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-Pehrson0cc2f952002-10-03 06:32:37 -0500[diff] [blame^]13might be called "libpng-1.2.5" or "lpng109" and "zlib-1.1.4"
Glenn Randers-Pehrsond1e8c862002-06-20 06:54:34 -0500[diff] [blame]14or "zlib114") so that you have directories called "zlib" and "libpng".

Glenn Randers-Pehrsondb66d442000-06-23 21:38:16 -0500[diff] [blame]52If you are building libpng with MSVC, you can enter the libpng\msvc directory
Glenn Randers-Pehrsonb1828932001-06-23 08:03:17 -0500[diff] [blame]53and follow the instructions in msvc\README.txt.

55You can build libpng for WindowsCE by entering the downloading and installing
56the libpng\wince directory as instructed in the projects\wince.txt file, and
57then following the instructions in the README* files. Similarly, you can
58build libpng for Netware as instructed in projects\netware.txt.

122Copy the file (or files) that you need from the
123scripts directory into this directory, for example
124
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]125 MSDOS example: copy scripts\makefile.msc makefile
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]126 UNIX example: cp scripts/makefile.std makefile
127
128Read the makefile to see if you need to change any source or
129target directories to match your preferences.
130
131Then read pngconf.h to see if you want to make any configuration
132changes.
133
134Then just run "make test" which will create the libpng library in
135this directory and run a quick test that reads the "pngtest.png"
136file and writes a "pngout.png" file that should be identical to it.
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]137Look for "9782 zero samples" in the output of the test. For more
138confidence, you can run another test by typing "pngtest pngnow.png"
Glenn Randers-Pehrson6d8f3b01999-10-23 08:39:18 -0500[diff] [blame]139and looking for "289 zero samples" in the output. Also, you can
140run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare
141your output with the result shown in contrib/pngsuite/README.
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]142
143Most of the makefiles will allow you to run "make install" to
144put the library in its final resting place (if you want to
145do that, run "make install" in the zlib directory first if necessary).
Glenn Randers-Pehrsond1e8c862002-06-20 06:54:34 -0500[diff] [blame]146Some also allow you to run "make test-installed" after you have
Glenn Randers-Pehrson0cc2f952002-10-03 06:32:37 -0500[diff] [blame^]147run "make install".
