Glenn Randers-Pehrson6d8f3b01999-10-23 08:39:18 -0500[diff] [blame^]2Installing libpng version 1.0.5a - October 23, 1999

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-Pehrson6d8f3b01999-10-23 08:39:18 -0500[diff] [blame^]13might be called "libpng-1.0.5a" or "lpng103" 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".

16Your directory structure should look like this:

18 .. (the parent directory)
19 libpng (this directory)
20 INSTALL (this file)
21 README
22 *.h
23 *.c

39First enter the zlib directory and follow the instructions
40in zlib/README. Then come back here and choose the
41appropriate makefile.sys in the scripts directory.

81Copy the file (or files) that you need from the
82scripts directory into this directory, for example
83
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]84 MSDOS example: copy scripts\makefile.msc makefile
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]85 UNIX example: cp scripts/makefile.std makefile
86
87Read the makefile to see if you need to change any source or
88target directories to match your preferences.
89
90Then read pngconf.h to see if you want to make any configuration
91changes.
92
93Then just run "make test" which will create the libpng library in
94this directory and run a quick test that reads the "pngtest.png"
95file and writes a "pngout.png" file that should be identical to it.
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]96Look for "9782 zero samples" in the output of the test. For more
97confidence, you can run another test by typing "pngtest pngnow.png"
Glenn Randers-Pehrson6d8f3b01999-10-23 08:39:18 -0500[diff] [blame^]98and looking for "289 zero samples" in the output. Also, you can
99run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare
100your output with the result shown in contrib/pngsuite/README.
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]101
102Most of the makefiles will allow you to run "make install" to
103put the library in its final resting place (if you want to
104do that, run "make install" in the zlib directory first if necessary).
