-Installing libpng version 1.2.7 - September 12, 2004
+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-1.2.7" or "lpng109" and "zlib-1.2.1"
+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:
distribution of libpng. It is available in both tar.gz (UNIX style line
endings) and zip (DOS style line endings) formats.
-
If you are building libpng with MSVC, you can enter the
libpng projects\visualc6 directory and follow the instructions in
projects\visualc6\README.txt.
or projects\beos.
Else enter the zlib directory and follow the instructions in zlib/README,
-then come back here and choose the appropriate makefile.sys in the scripts
-directory.
+then come back here and run "configure" or choose the appropriate
+makefile.sys in the scripts directory.
