Glenn Randers-Pehrson520a7642000-03-21 05:13:06 -0600[diff] [blame^]2Installing libpng version 1.0.6 - March 21, 2000

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-Pehrson520a7642000-03-21 05:13:06 -0600[diff] [blame^]13might be called "libpng-1.0.6" 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)

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.

90Copy the file (or files) that you need from the
91scripts directory into this directory, for example
92
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]93 MSDOS example: copy scripts\makefile.msc makefile
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]94 UNIX example: cp scripts/makefile.std makefile
95
96Read the makefile to see if you need to change any source or
97target directories to match your preferences.
98
99Then read pngconf.h to see if you want to make any configuration
100changes.
101
102Then just run "make test" which will create the libpng library in
103this directory and run a quick test that reads the "pngtest.png"
104file and writes a "pngout.png" file that should be identical to it.
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]105Look for "9782 zero samples" in the output of the test. For more
106confidence, you can run another test by typing "pngtest pngnow.png"
Glenn Randers-Pehrson6d8f3b01999-10-23 08:39:18 -0500[diff] [blame]107and looking for "289 zero samples" in the output. Also, you can
108run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare
109your output with the result shown in contrib/pngsuite/README.
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]110
111Most of the makefiles will allow you to run "make install" to
112put the library in its final resting place (if you want to
113do that, run "make install" in the zlib directory first if necessary).

Glenn Randers-Pehrson6d8f3b01999-10-23 08:39:18 -0500[diff] [blame]116files, in the individual makefiles, in png.h, and the manual pages
117libpng.3 and png.5.
