| 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 |
Glenn Randers-Pehrson | 5c6aeb2 | 1998-12-29 11:47:59 -0600 | [diff] [blame] | 8 | zlib, but you will still need to have access to the |
Glenn Randers-Pehrson | 08a3343 | 1998-03-07 06:06:55 -0600 | [diff] [blame] | 9 | zlib.h and zconf.h include files that correspond to the |
| 10 | version of zlib that's installed. |
| 11 | |
| 12 | You can rename the directories that you downloaded (they |
Glenn Randers-Pehrson | 584b96e | 2004-11-29 15:08:00 -0600 | [diff] [blame^] | 13 | might be called "libpng-1.2.8rc5" or "lpng109" and "zlib-1.2.1" |
Glenn Randers-Pehrson | 16e1166 | 2004-11-01 14:13:40 -0600 | [diff] [blame] | 14 | or "zlib121") so that you have directories called "zlib" and "libpng". |

| 135 | Read the makefile to see if you need to change any source or |

Glenn Randers-Pehrson | 16e1166 | 2004-11-01 14:13:40 -0600 | [diff] [blame] | 141 | Then just run "make" which will create the libpng library in |
| 142 | this directory and "make test" which will run a quick test that reads |
| 143 | the "pngtest.png" file and writes a "pngout.png" file that should be |
| 144 | identical to it. Look for "9782 zero samples" in the output of the |
| 145 | test. For more confidence, you can run another test by typing |
| 146 | "pngtest pngnow.png" and looking for "289 zero samples" in the output. |
| 147 | Also, you can run "pngtest -m contrib/pngsuite/*.png" and compare |
Glenn Randers-Pehrson | 6d8f3b0 | 1999-10-23 08:39:18 -0500 | [diff] [blame] | 148 | your output with the result shown in contrib/pngsuite/README. |

| 151 | put the library in its final resting place (if you want to |
| 152 | do that, run "make install" in the zlib directory first if necessary). |
Glenn Randers-Pehrson | d1e8c86 | 2002-06-20 06:54:34 -0500 | [diff] [blame] | 153 | Some also allow you to run "make test-installed" after you have |

| 158 | __png.h__ already includes setjmp.h; |

| 160 | This means you have compiled another module that includes setjmp.h, |
| 161 | which is hazardous because the two modules might not include exactly |
| 162 | the same setjmp.h. If you are sure that you know what you are doing |
| 163 | and that they are exactly the same, then you can comment out or |
| 164 | delete the two lines. Better yet, use the cexcept interface |
| 165 | instead, as demonstrated in contrib/visupng of the libpng distribution. |
