-Installing libpng version 1.2.4 - July 8, 2002
+Installing libpng version 1.2.20 - September 8, 2007
-Before installing libpng, you must first install zlib. zlib
-can usually be found wherever you got libpng. zlib can be
-placed in another directory, at the same level as libpng.
-Note that your system might already have a preinstalled
-zlib, but you will still need to have access to the
-zlib.h and zconf.h include files that correspond to the
-version of zlib that's installed.
+On Unix/Linux and similar systems, you can simply type
+
+ ./configure [--prefix=/path]
+ make check
+ make install
+
+and ignore the rest of this document.
+
+If configure does not work on your system and you have a reasonably
+up-to-date set of tools, running ./autogen.sh before running ./configure
+may fix the problem. You can also run the individual commands in
+autogen.sh with the --force option, if supported by your version of
+the tools. If you run 'libtoolize --force', though, this will replace
+the distributed, patched, version of ltmain.sh with an unpatched version
+and your shared library builds may fail to produce libraries with the
+correct version numbers.
+
+Instead, you can use one of the custom-built makefiles in the
+"scripts" directory
+
+ cp scripts/makefile.system makefile
+ make test
+ make install
+
+Or you can use one of the "projects" in the "projects" directory.
+
+If you want to use "cmake" (see www.cmake.org), copy CMakeLists.txt
+from the "scripts" directory to this directory and type
+
+ cmake . [-DPNG_MMX=YES] -DCMAKE_INSTALL_PREFIX=/path
+ make
+ make install
+
+Before installing libpng, you must first install zlib, if it
+is not already on your system. zlib can usually be found
+wherever you got libpng. zlib can be placed in another directory,
+at the same level as libpng.
+
+If your system already has a preinstalled zlib you will still need
+to have access to the zlib.h and zconf.h include files that
+correspond to the version of zlib that's installed.
You can rename the directories that you downloaded (they
-might be called "libpng-1.2.4" or "lpng109" and "zlib-1.1.4"
-or "zlib114") so that you have directories called "zlib" and "libpng".
+might be called "libpng-1.2.20" or "lpng109" and "zlib-1.2.1"
+or "zlib121") so that you have directories called "zlib" and "libpng".
Your directory structure should look like this:
*.c
contrib
gregbook
- msvctest
pngminus

endings) and zip (DOS style line endings) formats.

Copy the file (or files) that you need from the
Then read pngconf.h to see if you want to make any configuration
changes.
-Then just run "make test" which will create the libpng library in
-this directory and run a quick test that reads the "pngtest.png"
-file and writes a "pngout.png" file that should be identical to it.
-Look for "9782 zero samples" in the output of the test. For more
-confidence, you can run another test by typing "pngtest pngnow.png"
-and looking for "289 zero samples" in the output. Also, you can
-run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare

Most of the makefiles will allow you to run "make install" to
put the library in its final resting place (if you want to
do that, run "make install" in the zlib directory first if necessary).
Some also allow you to run "make test-installed" after you have
-run "make install". This will build and run executables called "pngtesti"
-and "mangle/pngtestm".

-The files that are presently available in the mangle directory include the
-following. The makefiles are automatically run by the corresponding makefiles
-in the scripts directory when you run "make", "make install", or
-"make test-installed".

- mangle.in => Function-decoration macros added to png.h by the
- makefiles.

+If you encounter a compiler error message complaining about the
+lines
+ __png.h__ already includes setjmp.h;
+ __dont__ include it again.;
+This means you have compiled another module that includes setjmp.h,
+which is hazardous because the two modules might not include exactly
+the same setjmp.h. If you are sure that you know what you are doing
+and that they are exactly the same, then you can comment out or
+delete the two lines. Better yet, use the cexcept interface
+instead, as demonstrated in contrib/visupng of the libpng distribution.
