| 2 | Installing libpng version 1.2.5 - October 3, 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-1.2.5" 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)
|
|---|

| 48 | If the line endings in the files look funny, you may wish to get the other
|
|---|
| 49 | distribution of libpng. It is available in both tar.gz (UNIX style line
|
|---|
| 50 | endings) and zip (DOS style line endings) formats.
|
|---|
| 51 |
|
|---|
| 52 | If you are building libpng with MSVC, you can enter the libpng\msvc directory
|
|---|
| 53 | and follow the instructions in msvc\README.txt.
|
|---|
| 54 |
|
|---|
| 55 | You can build libpng for WindowsCE by entering the downloading and installing
|
|---|
| 56 | the libpng\wince directory as instructed in the projects\wince.txt file, and
|
|---|
| 57 | then following the instructions in the README* files. Similarly, you can
|
|---|
| 58 | build libpng for Netware as instructed in projects\netware.txt.
|
|---|
| 59 |
|
|---|
| 60 | Else enter the zlib directory and follow the instructions in zlib/README,
|
|---|
| 61 | then come back here and choose the appropriate makefile.sys in the scripts
|
|---|
| 62 | directory.
|
|---|
| 63 |

|---|

|---|
| 122 | Copy the file (or files) that you need from the
|
|---|
| 123 | scripts directory into this directory, for example
|
|---|
| 124 |
|
|---|
| 125 | MSDOS example: copy scripts\makefile.msc makefile
|
|---|
| 126 | UNIX example: cp scripts/makefile.std makefile
|
|---|
| 127 |
|
|---|
| 128 | Read the makefile to see if you need to change any source or
|
|---|
| 129 | target directories to match your preferences.
|
|---|
| 130 |
|
|---|
| 131 | Then read pngconf.h to see if you want to make any configuration
|
|---|
| 132 | changes.
|
|---|
| 133 |
|
|---|
| 134 | Then just run "make test" which will create the libpng library in
|
|---|
| 135 | this directory and run a quick test that reads the "pngtest.png"
|
|---|
| 136 | file and writes a "pngout.png" file that should be identical to it.
|
|---|
| 137 | Look for "9782 zero samples" in the output of the test. For more
|
|---|
| 138 | confidence, you can run another test by typing "pngtest pngnow.png"
|
|---|
| 139 | and looking for "289 zero samples" in the output. Also, you can
|
|---|
| 140 | run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare
|
|---|
| 141 | your output with the result shown in contrib/pngsuite/README.
|
|---|
| 142 |
|
|---|
| 143 | Most of the makefiles will allow you to run "make install" to
|
|---|
| 144 | put the library in its final resting place (if you want to
|
|---|
| 145 | do that, run "make install" in the zlib directory first if necessary).
|
|---|
| 146 | Some also allow you to run "make test-installed" after you have
|
|---|
| 147 | run "make install".
|
|---|
| 148 |
|
|---|
| 149 | Further information can be found in the README and libpng.txt
|
|---|
| 150 | files, in the individual makefiles, in png.h, in the README files in
|
|---|
| 151 | subdirectories of the LIB directory, and the manual pages libpng.3 and png.5.
