Glenn Randers-Pehrson8b6a8892001-05-18 04:54:50 -0500[diff] [blame^]2Installing libpng version 1.2.0beta3 - May 18, 2001

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-Pehrson8b6a8892001-05-18 04:54:50 -0500[diff] [blame^]13might be called "libpng-1.2.0beta3" 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".

19 libpng (this directory)
20 INSTALL (this file)

Glenn Randers-Pehrsondb66d442000-06-23 21:38:16 -0500[diff] [blame]50If you are building libpng with MSVC, you can enter the libpng\msvc directory
Glenn Randers-Pehrson15dac0b2000-07-10 07:48:54 -0500[diff] [blame]51and follow the instructions in msvc\README.txt. You can build libpng for
52WindowsCE by entering the libpng\wince directory and following the
53instructions in the README* files.

110Copy the file (or files) that you need from the
111scripts directory into this directory, for example
112
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]113 MSDOS example: copy scripts\makefile.msc makefile
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]114 UNIX example: cp scripts/makefile.std makefile
115
116Read the makefile to see if you need to change any source or
117target directories to match your preferences.
118
119Then read pngconf.h to see if you want to make any configuration
120changes.
121
122Then just run "make test" which will create the libpng library in
123this directory and run a quick test that reads the "pngtest.png"
124file and writes a "pngout.png" file that should be identical to it.
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]125Look for "9782 zero samples" in the output of the test. For more
126confidence, you can run another test by typing "pngtest pngnow.png"
Glenn Randers-Pehrson6d8f3b01999-10-23 08:39:18 -0500[diff] [blame]127and looking for "289 zero samples" in the output. Also, you can
128run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare
129your output with the result shown in contrib/pngsuite/README.
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]130
131Most of the makefiles will allow you to run "make install" to
132put the library in its final resting place (if you want to
133do that, run "make install" in the zlib directory first if necessary).
