-Installing libpng version 1.0.1 March 15, 1998
+Installing libpng version 1.2.5rc3 - September 18, 2002
Before installing libpng, you must first install zlib. zlib
can usually be found wherever you got libpng. zlib can be
placed in another directory, at the same level as libpng.
Note that your system might already have a preinstalled
-zlib, but you will still need to have access to the
+zlib, but you will still need to have access to the
zlib.h and zconf.h include files that correspond to the
version of zlib that's installed.
You can rename the directories that you downloaded (they
-might be called "libpng-1.0.1 or "lpng100" and "zlib-1.1.1"
-or "zlib111") so that you have directories called "zlib" and "libpng".
+might be called "libpng-1.2.5rc3" or "lpng109" and "zlib-1.1.4"
+or "zlib114") so that you have directories called "zlib" and "libpng".
Your directory structure should look like this:
README
*.h
*.c
+ contrib
+ gregbook
+ msvctest
+ pngminus
+ pngsuite
+ visupng
+ projects
+ beos
+ borland
+ msvc
+ netware.txt
+ wince.txt
scripts
makefile.*
+ libpng*.in
+ mangle
+ makefile.*
+ mangle.in
pngtest.png
etc.
zlib
contrib
etc.
-First enter the zlib directory and follow the instructions
-in zlib/README. Then come back here and choose the
-appropriate makefile.sys in the scripts directory.
+If the line endings in the files look funny, you may wish to get the other
+distribution of libpng. It is available in both tar.gz (UNIX style line
+endings) and zip (DOS style line endings) formats.
+
+If you are building libpng with MSVC, you can enter the libpng\msvc directory
+and follow the instructions in msvc\README.txt.
+
+You can build libpng for WindowsCE by entering the downloading and installing
+the libpng\wince directory as instructed in the projects\wince.txt file, and
+then following the instructions in the README* files. Similarly, you can
+build libpng for Netware as instructed in projects\netware.txt.
+
+Else enter the zlib directory and follow the instructions in zlib/README,
+then come back here and choose the appropriate makefile.sys in the scripts
+directory.
+

Copy the file (or files) that you need from the
scripts directory into this directory, for example
- MSDOS example: copy scripts\makefile.msd makefile
+ MSDOS example: copy scripts\makefile.msc makefile
UNIX example: cp scripts/makefile.std makefile
Read the makefile to see if you need to change any source or
Then just run "make test" which will create the libpng library in
this directory and run a quick test that reads the "pngtest.png"
file and writes a "pngout.png" file that should be identical to it.
+Look for "9782 zero samples" in the output of the test. For more
+confidence, you can run another test by typing "pngtest pngnow.png"
+and looking for "289 zero samples" in the output. Also, you can
+run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare
+your output with the result shown in contrib/pngsuite/README.
Most of the makefiles will allow you to run "make install" to
put the library in its final resting place (if you want to
do that, run "make install" in the zlib directory first if necessary).
+Some also allow you to run "make test-installed" after you have
+run "make install". This will build and run executables called "pngtesti"
+and "mangle/pngtestm".
+
+The files that are presently available in the mangle directory include the
+following. The makefiles are automatically run by the corresponding makefiles
+in the scripts directory when you run "make", "make install", or
+"make test-installed".
+
+ mangle.in => Function-decoration macros added to png.h by the
+ makefiles.
+ makefile.linux => Linux/ELF makefile
+ (gcc, creates libpng12m.so.0.1.2.5rc3)
+ makefile.gcmmx => Linux/ELF makefile (gcc, creates
+ libpng12.so.0m.1.2.5rc3, uses assembler code
+ tuned for Intel MMX platform)
+ makefile.sgi => Silicon Graphics (cc, creates libpng12m.so)
+ makefile.sggcc => Silicon Graphics (gcc, creates libpng12m.so)
