Glenn Randers-Pehrsonec61c232000-05-16 06:17:36 -0500[diff] [blame^]2Installing libpng version 1.0.7beta13 - May 16, 2000
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-Pehrsonec61c232000-05-16 06:17:36 -0500[diff] [blame^]13might be called "libpng-1.0.7beta13" or "lpng106" 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)
21 README

Glenn Randers-Pehrson61c32d92000-02-04 23:40:16 -0600[diff] [blame]39If the line endings in the files look funny, you may wish to get the other
40distribution of libpng. It is available in both tar.gz (UNIX style line
41endings) and zip (DOS style line endings) formats.

Glenn Randers-Pehrson520a7642000-03-21 05:13:06 -0600[diff] [blame]43First enter the zlib directory and follow the instructions in zlib/README.
44Then come back here and choose the appropriate makefile.sys in the scripts
45directory.

92Copy the file (or files) that you need from the
93scripts directory into this directory, for example
94
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]95 MSDOS example: copy scripts\makefile.msc makefile
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]96 UNIX example: cp scripts/makefile.std makefile
97
98Read the makefile to see if you need to change any source or
99target directories to match your preferences.
100
101Then read pngconf.h to see if you want to make any configuration
102changes.
103
104Then just run "make test" which will create the libpng library in
105this directory and run a quick test that reads the "pngtest.png"
106file and writes a "pngout.png" file that should be identical to it.
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]107Look for "9782 zero samples" in the output of the test. For more
108confidence, you can run another test by typing "pngtest pngnow.png"
Glenn Randers-Pehrson6d8f3b01999-10-23 08:39:18 -0500[diff] [blame]109and looking for "289 zero samples" in the output. Also, you can
110run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare
111your output with the result shown in contrib/pngsuite/README.
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]112
113Most of the makefiles will allow you to run "make install" to
114put the library in its final resting place (if you want to
115do that, run "make install" in the zlib directory first if necessary).

119libpng.3 and png.5.
