| 4 | Before installing libpng, you must first install zlib. zlib |
| 5 | can usually be found wherever you got libpng. zlib can be |
| 6 | placed in another directory, at the same level as libpng. |
| 7 | Note that your system might already have a preinstalled |

| 10 | version of zlib that's installed. |

| 96 | Read the makefile to see if you need to change any source or |
| 97 | target directories to match your preferences. |
| 98 | |
| 99 | Then read pngconf.h to see if you want to make any configuration |
| 100 | changes. |
| 101 | |
| 102 | Then just run "make test" which will create the libpng library in |
| 103 | this directory and run a quick test that reads the "pngtest.png" |
| 104 | file and writes a "pngout.png" file that should be identical to it. |

Glenn Randers-Pehrson | 6d8f3b0 | 1999-10-23 08:39:18 -0500 | [diff] [blame] | 107 | and looking for "289 zero samples" in the output. Also, you can |
| 108 | run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare |
| 109 | your output with the result shown in contrib/pngsuite/README. |

| 111 | Most of the makefiles will allow you to run "make install" to |
| 112 | put the library in its final resting place (if you want to |
| 113 | do that, run "make install" in the zlib directory first if necessary). |
