-Installing libpng version 1.2.5rc3 - September 18, 2002
+Installing libpng version 1.2.7 - September 12, 2004
Before installing libpng, you must first install zlib. zlib
can usually be found wherever you got libpng. zlib can be
version of zlib that's installed.
You can rename the directories that you downloaded (they
-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".
+might be called "libpng-1.2.7" or "lpng109" and "zlib-1.2.1"
+or "zlib121") so that you have directories called "zlib" and "libpng".
Your directory structure should look like this:
*.c
contrib
gregbook
- msvctest
pngminus
pngsuite
visupng
projects
beos
- borland
- msvc
+ c5builder (Borland)
+ visualc6 (msvc)
netware.txt
wince.txt
scripts
makefile.*
- libpng*.in
- mangle
- makefile.*
- mangle.in
pngtest.png
etc.

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
+If you are building libpng with MSVC, you can enter the
+libpng projects\visualc6 directory and follow the instructions in
+projects\visualc6\README.txt.
+
+You can build libpng for WindowsCE by downloading and installing
+the projects\wince directory as instructed in the projects\wince.txt file, and
then following the instructions in the README* files. Similarly, you can

Then read pngconf.h to see if you want to make any configuration
changes.

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".

- makefiles.

+If you encounter a compiler error message complaining about the
+lines
+ __png.h__ already includes setjmp.h;
+ __dont__ include it again.;
+This means you have compiled another module that includes setjmp.h,
+which is hazardous because the two modules might not include exactly
+the same setjmp.h. If you are sure that you know what you are doing
+and that they are exactly the same, then you can comment out or
+delete the two lines. Better yet, use the cexcept interface
+instead, as demonstrated in contrib/visupng of the libpng distribution.
