| Installing libpng version 1.2.38 - July 16, 2009 |
| |
| 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-1.2.38" 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. |
