Glenn Randers-Pehrson9c3ab682006-02-20 22:09:05 -06002Installing libpng version 1.2.9beta1 - February 21, 2006
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -06003
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 -06008zlib, but you will still need to have access to the
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -06009zlib.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-Pehrson9c3ab682006-02-20 22:09:05 -060013might be called "libpng-1.2.9beta1" or "lpng109" and "zlib-1.2.1"
14or "zlib121") so that you have directories called "zlib" and "libpng".
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -060015
16Your directory structure should look like this:
17
18 .. (the parent directory)
19 libpng (this directory)
20 INSTALL (this file)
21 README
22 *.h
23 *.c

Glenn Randers-Pehrson61c32d92000-02-04 23:40:16 -060046If the line endings in the files look funny, you may wish to get the other
47distribution of libpng. It is available in both tar.gz (UNIX style line
48endings) and zip (DOS style line endings) formats.

Glenn Randers-Pehrson9c3ab682006-02-20 22:09:05 -060051If you are building libpng with MSVC, you can enter the
52libpng projects\visualc6 directory and follow the instructions in
53projects\visualc6\README.txt.
54
55You can build libpng for WindowsCE by downloading and installing
56the projects\wince directory as instructed in the projects\wince.txt file, and
Glenn Randers-Pehrsonb1828932001-06-23 08:03:17 -050057then following the instructions in the README* files. Similarly, you can
Glenn Randers-Pehrson9c3ab682006-02-20 22:09:05 -060058build libpng for Netware or Beos as instructed in projects\netware.txt
59or projects\beos.

Glenn Randers-Pehrsondb66d442000-06-23 21:38:16 -050061Else enter the zlib directory and follow the instructions in zlib/README,
62then come back here and choose the appropriate makefile.sys in the scripts

129Copy the file (or files) that you need from the
130scripts directory into this directory, for example
131
Glenn Randers-Pehrson860ab2b1999-10-14 07:43:10 -0500132 MSDOS example: copy scripts\makefile.msc makefile
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600133 UNIX example: cp scripts/makefile.std makefile
134
135Read the makefile to see if you need to change any source or
136target directories to match your preferences.
137
138Then read pngconf.h to see if you want to make any configuration
139changes.
140
Glenn Randers-Pehrson9c3ab682006-02-20 22:09:05 -0600141Then just run "make" which will create the libpng library in
142this directory and "make test" which will run a quick test that reads
143the "pngtest.png" file and writes a "pngout.png" file that should be
144identical to it. Look for "9782 zero samples" in the output of the
145test. For more confidence, you can run another test by typing
146"pngtest pngnow.png" and looking for "289 zero samples" in the output.
147Also, you can run "pngtest -m contrib/pngsuite/*.png" and compare
Glenn Randers-Pehrson6d8f3b01999-10-23 08:39:18 -0500148your output with the result shown in contrib/pngsuite/README.
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600149
150Most of the makefiles will allow you to run "make install" to
151put the library in its final resting place (if you want to
152do that, run "make install" in the zlib directory first if necessary).
Glenn Randers-Pehrsond1e8c862002-06-20 06:54:34 -0500153Some also allow you to run "make test-installed" after you have
Glenn Randers-Pehrson0cc2f952002-10-03 06:32:37 -0500154run "make install".
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600155
Glenn Randers-Pehrson9c3ab682006-02-20 22:09:05 -0600156If you encounter a compiler error message complaining about the
157lines
158 __png.h__ already includes setjmp.h;
159 __dont__ include it again.;
160This means you have compiled another module that includes setjmp.h,
161which is hazardous because the two modules might not include exactly
162the same setjmp.h. If you are sure that you know what you are doing
163and that they are exactly the same, then you can comment out or
164delete the two lines. Better yet, use the cexcept interface
165instead, as demonstrated in contrib/visupng of the libpng distribution.
166
Glenn Randers-Pehrson08a33431998-03-07 06:06:55 -0600167Further information can be found in the README and libpng.txt
Glenn Randers-Pehrson9c3ab682006-02-20 22:09:05 -0600168files, in the individual makefiles, in png.h, and the manual pages
169libpng.3 and png.5.

172Using the ./configure script -- 16 December 2002.
173=================================================
174
175
176The ./configure script should work compatibly with what scripts/makefile.*
177did, however there are some options you need to add to configure explicitly,
178which previously was done semi-automatically (if you didn't edit
179scripts/makefile.* yourself, that is)
180
181
182CFLAGS="-Wall -O3 -funroll-loops \
183-malign-loops=2 -malign-functions=2" ./configure --prefix=/usr/include \
184--with-pkgconfigdir=/usr/lib/pkgconfig --includedir=/usr/include
185
186You can alternatively specify --includedir=/usr/include, /usr/local/include,
187/usr/include/png12, or whatever.
188
