   2 Installing libpng version 1.2.4 - July 8, 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-1.2.4" 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

  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.0.1.2.4)
 162  makefile.gcmmx   =>  Linux/ELF makefile (gcc, creates
 163                       libpng12.so.0m.1.2.4, 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.
