Glenn Randers-Pehrsond1e8c862002-06-20 06:54:34 -0500[diff] [blame^]2Installing libpng version 1.2.4beta2 - June 20, 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-Pehrsond1e8c862002-06-20 06:54:34 -0500[diff] [blame^]13might be called "libpng-1.2.4beta2" or "lpng109" and "zlib-1.1.4"
14or "zlib114") so that you have directories called "zlib" and "libpng".
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]15
16Your directory structure should look like this:

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

Glenn Randers-Pehrsondb66d442000-06-23 21:38:16 -0500[diff] [blame]55If you are building libpng with MSVC, you can enter the libpng\msvc directory
Glenn Randers-Pehrsonb1828932001-06-23 08:03:17 -0500[diff] [blame]56and follow the instructions in msvc\README.txt.
57
58You can build libpng for WindowsCE by entering the downloading and installing
59the libpng\wince directory as instructed in the projects\wince.txt file, and
60then following the instructions in the README* files. Similarly, you can
61build libpng for Netware as instructed in projects\netware.txt.

125Copy the file (or files) that you need from the
126scripts directory into this directory, for example
127
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]128 MSDOS example: copy scripts\makefile.msc makefile
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]129 UNIX example: cp scripts/makefile.std makefile
130
131Read the makefile to see if you need to change any source or
132target directories to match your preferences.
133
134Then read pngconf.h to see if you want to make any configuration
135changes.
136
137Then just run "make test" which will create the libpng library in
138this directory and run a quick test that reads the "pngtest.png"
139file and writes a "pngout.png" file that should be identical to it.
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]140Look for "9782 zero samples" in the output of the test. For more
141confidence, you can run another test by typing "pngtest pngnow.png"
Glenn Randers-Pehrson6d8f3b01999-10-23 08:39:18 -0500[diff] [blame]142and looking for "289 zero samples" in the output. Also, you can
143run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare
144your output with the result shown in contrib/pngsuite/README.
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]145
146Most of the makefiles will allow you to run "make install" to
147put the library in its final resting place (if you want to
148do that, run "make install" in the zlib directory first if necessary).
Glenn Randers-Pehrsond1e8c862002-06-20 06:54:34 -0500[diff] [blame^]149Some also allow you to run "make test-installed" after you have
150run "make install". This will build and run executables called "pngtesti"
151and "mangle/pngtestm".
152
153The files that are presently available in the mangle directory include the
154following. The makefiles are automatically run by the corresponding makefiles
155in the scripts directory when you run "make", "make install", or
156"make test-installed".
157
158 mangle.in => Function-decoration macros added to png.h by the
159 makefiles.
160 makefile.linux => Linux/ELF makefile
161 (gcc, creates libpng12m.so.0.1.2.4beta2)
162 makefile.gcmmx => Linux/ELF makefile (gcc, creates
163 libpng12.so.0m.1.2.4beta2, uses assembler code
164 tuned for Intel MMX platform)
165 makefile.sgi => Silicon Graphics (cc, creates libpng12m.so)
166 makefile.sggcc => Silicon Graphics (gcc, creates libpng12m.so)
