| 2 | Installing libpng version 1.2.5rc3 - September 18, 2002 |
| 3 | |
| 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 |
| 8 | zlib, but you will still need to have access to the |
| 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 |
| 13 | might be called "libpng-1.2.5rc3" or "lpng109" and "zlib-1.1.4" |
| 14 | or "zlib114") so that you have directories called "zlib" and "libpng". |
| 15 | |
| 16 | Your directory structure should look like this: |
| 17 | |
| 18 | .. (the parent directory) |
| 19 | libpng (this directory) |
| 20 | INSTALL (this file) |
| 21 | README |
| 22 | *.h |
| 23 | *.c |
| 24 | contrib |
| 25 | gregbook |
| 26 | msvctest |
| 27 | pngminus |
| 28 | pngsuite |
| 29 | visupng |
| 30 | projects |
| 31 | beos |
| 32 | borland |
| 33 | msvc |
| 34 | netware.txt |
| 35 | wince.txt |
| 36 | scripts |
| 37 | makefile.* |
| 38 | libpng*.in |
| 39 | mangle |
| 40 | makefile.* |
| 41 | mangle.in |
| 42 | pngtest.png |
| 43 | etc. |
| 44 | zlib |
| 45 | README |
| 46 | *.h |
| 47 | *.c |
| 48 | contrib |
| 49 | etc. |
| 50 | |
| 51 | If the line endings in the files look funny, you may wish to get the other |
| 52 | distribution of libpng. It is available in both tar.gz (UNIX style line |
| 53 | endings) and zip (DOS style line endings) formats. |
| 54 | |
| 55 | If you are building libpng with MSVC, you can enter the libpng\msvc directory |
| 56 | and follow the instructions in msvc\README.txt. |
| 57 | |
| 58 | You can build libpng for WindowsCE by entering the downloading and installing |
| 59 | the libpng\wince directory as instructed in the projects\wince.txt file, and |
| 60 | then following the instructions in the README* files. Similarly, you can |
| 61 | build libpng for Netware as instructed in projects\netware.txt. |
| 62 | |
| 63 | Else enter the zlib directory and follow the instructions in zlib/README, |
| 64 | then come back here and choose the appropriate makefile.sys in the scripts |
| 65 | directory. |
| 66 | |

| 124 | |
| 125 | Copy the file (or files) that you need from the |
| 126 | scripts directory into this directory, for example |
| 127 | |
| 128 | MSDOS example: copy scripts\makefile.msc makefile |
| 129 | UNIX example: cp scripts/makefile.std makefile |
| 130 | |
| 131 | Read the makefile to see if you need to change any source or |
| 132 | target directories to match your preferences. |
| 133 | |
| 134 | Then read pngconf.h to see if you want to make any configuration |
| 135 | changes. |
| 136 | |
| 137 | Then just run "make test" which will create the libpng library in |
| 138 | this directory and run a quick test that reads the "pngtest.png" |
| 139 | file and writes a "pngout.png" file that should be identical to it. |
| 140 | Look for "9782 zero samples" in the output of the test. For more |
| 141 | confidence, you can run another test by typing "pngtest pngnow.png" |
| 142 | and looking for "289 zero samples" in the output. Also, you can |
| 143 | run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare |
| 144 | your output with the result shown in contrib/pngsuite/README. |
| 145 | |
| 146 | Most of the makefiles will allow you to run "make install" to |
| 147 | put the library in its final resting place (if you want to |
| 148 | do that, run "make install" in the zlib directory first if necessary). |
| 149 | Some also allow you to run "make test-installed" after you have |
| 150 | run "make install". This will build and run executables called "pngtesti" |
| 151 | and "mangle/pngtestm". |
| 152 | |
| 153 | The files that are presently available in the mangle directory include the |
| 154 | following. The makefiles are automatically run by the corresponding makefiles |
| 155 | in the scripts directory when you run "make", "make install", or |
| 156 | "make test-installed". |
| 157 | |
| 158 | mangle.in => Function-decoration macros added to png.h by the |
| 159 | makefiles. |
| 160 | makefile.linux => Linux/ELF makefile |
| 161 | (gcc, creates libpng12m.so.0.1.2.5rc3) |
| 162 | makefile.gcmmx => Linux/ELF makefile (gcc, creates |
| 163 | libpng12.so.0m.1.2.5rc3, uses assembler code |
| 164 | tuned for Intel MMX platform) |
| 165 | makefile.sgi => Silicon Graphics (cc, creates libpng12m.so) |
| 166 | makefile.sggcc => Silicon Graphics (gcc, creates libpng12m.so) |
| 167 | |
| 168 | Further information can be found in the README and libpng.txt |
| 169 | files, in the individual makefiles, in png.h, in the README files in |
| 170 | subdirectories of the LIB directory, and the manual pages libpng.3 and png.5. |
