-Installing libpng version 1.2.29 - May 8, 2008
-
-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-1.2.29" 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:
-
- .. (the parent directory)
- libpng (this directory)
- INSTALL (this file)
- README
- *.h
- *.c
- contrib
- gregbook
- pngminus
- pngsuite
- visupng
- projects
- beos
- c5builder (Borland)
- visualc6 (msvc)
- netware.txt
- wince.txt
- scripts
- makefile.*
- pngtest.png
- etc.
- zlib
- README
- *.h
- *.c
- contrib
- etc.
-
-If the line endings in the files look funny, you may wish to get the other
-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.
-
-You can build libpng for WindowsCE by downloading and installing
-the projects\wince directory as instructed in the projects\wince.txt file, and
-then following the instructions in the README* files. Similarly, you can
-build libpng for Netware or Beos as instructed in projects\netware.txt
-or projects\beos.
-
-Else enter the zlib directory and follow the instructions in zlib/README,
-then come back here and run "configure" or choose the appropriate
-makefile.sys in the scripts directory.

-
-Copy the file (or files) that you need from the
-scripts directory into this directory, for example
-
- MSDOS example: copy scripts\makefile.msc makefile
- UNIX example: cp scripts/makefile.std makefile
-
-Read the makefile to see if you need to change any source or
-target directories to match your preferences.
-
-Then read pngconf.h to see if you want to make any configuration
-changes.
-
-Then just run "make" which will create the libpng library in
-this directory and "make test" which will 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 contrib/pngsuite/*.png" and compare
-your output with the result shown in contrib/pngsuite/README.
-
-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".
-
-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.
-
-Further information can be found in the README and libpng.txt
-files, in the individual makefiles, in png.h, and the manual pages
-libpng.3 and png.5.
-
-
-Using the ./configure script -- 16 December 2002.
-=================================================
-
-
-The ./configure script should work compatibly with what scripts/makefile.*
-did, however there are some options you need to add to configure explicitly,
-which previously was done semi-automatically (if you didn't edit
-scripts/makefile.* yourself, that is)
-
-
-CFLAGS="-Wall -O -funroll-loops \
--malign-loops=2 -malign-functions=2" ./configure --prefix=/usr/include \
---with-pkgconfigdir=/usr/lib/pkgconfig --includedir=/usr/include
-
-You can alternatively specify --includedir=/usr/include, /usr/local/include,
-/usr/include/png12, or whatever.
