| Installing libpng version 1.0.14 - July 8, 2002 |
| |
| 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. |
| |
| You can rename the directories that you downloaded (they |
| might be called "libpng-1.0.14" or "lpng109" and "zlib-1.1.3" |
| or "zlib113") 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 |
| msvctest |
| pngminus |
| pngsuite |
| visupng |
| projects |
| beos |
| borland |
| 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\msvc directory |
| and follow the instructions in msvc\README.txt. |
| |
| You can build libpng for WindowsCE by entering the downloading and installing |
| the libpng\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 as instructed in projects\netware.txt. |
| |
| 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. |
| |

| SCOPTIONS.ppc => Used with smakefile.ppc |
| |
| 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 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 |
| 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). |
| |
| Further information can be found in the README and libpng.txt |
| files, in the individual makefiles, in png.h, in the README files in |
| subdirectories of the LIB directory, and the manual pages libpng.3 and png.5. |
