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-Pehrson917648e2004-12-02 18:14:51 -0600[diff] [blame^]13might be called "libpng-1.2.8" or "lpng109" and "zlib-1.1.3"
14or "zlib113") 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:

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

121Copy the file (or files) that you need from the
122scripts directory into this directory, for example
123
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500[diff] [blame]124 MSDOS example: copy scripts\makefile.msc makefile
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]125 UNIX example: cp scripts/makefile.std makefile
126
127Read the makefile to see if you need to change any source or
128target directories to match your preferences.
129
130Then read pngconf.h to see if you want to make any configuration
131changes.
132
Glenn Randers-Pehrson917648e2004-12-02 18:14:51 -0600[diff] [blame^]133Then just run "make test" which will create the libpng library in
134this directory and run a quick test that reads the "pngtest.png"
135file and writes a "pngout.png" file that should be identical to it.
136Look for "9782 zero samples" in the output of the test. For more
137confidence, you can run another test by typing "pngtest pngnow.png"
138and looking for "289 zero samples" in the output. Also, you can
139run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare
Glenn Randers-Pehrson6d8f3b01999-10-23 08:39:18 -0500[diff] [blame]140your output with the result shown in contrib/pngsuite/README.
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600[diff] [blame]141
142Most of the makefiles will allow you to run "make install" to
143put the library in its final resting place (if you want to
144do that, run "make install" in the zlib directory first if necessary).
Glenn Randers-Pehrsond1e8c862002-06-20 06:54:34 -0500[diff] [blame]145Some also allow you to run "make test-installed" after you have
Glenn Randers-Pehrson0cc2f952002-10-03 06:32:37 -0500[diff] [blame]146run "make install".

Glenn Randers-Pehrson917648e2004-12-02 18:14:51 -0600[diff] [blame^]149files, in the individual makefiles, in png.h, in the README files in
150subdirectories of the LIB directory, and the manual pages libpng.3 and png.5.

153Using the ./configure script -- 16 December 2002.
154=================================================
155
156
157The ./configure script should work compatibly with what scripts/makefile.*
158did, however there are some options you need to add to configure explicitly,
159which previously was done semi-automatically (if you didn't edit
160scripts/makefile.* yourself, that is)
161
162
163CFLAGS="-Wall -O3 -funroll-loops \
164-malign-loops=2 -malign-functions=2" ./configure --prefix=/usr/include \
165--with-pkgconfigdir=/usr/lib/pkgconfig --includedir=/usr/include
166
167You can alternatively specify --includedir=/usr/include, /usr/local/include,
168/usr/include/png12, or whatever.
