Installing libpng version 1.2.11beta3 - June 5, 2006
|
|
|
|
On Unix/Linux and similar systems, you can simply type
|
|
|
|
./autogen.sh
|
|
./configure [--prefix=$HOME]
|
|
make check
|
|
make install
|
|
|
|
and ignore the rest of this document.
|
|
|
|
Or you can use one of the custom-built makefiles in the
|
|
"scripts" directory
|
|
|
|
cp scripts/makefile.system makefile
|
|
make test
|
|
make install
|
|
|
|
Or you can use one of the "projects" in the "projects" directory.
|
|
|
|
Before installing libpng, you must first install zlib, if it
|
|
is not already on your system. zlib can usually be found
|
|
wherever you got libpng. zlib can be placed in another directory,
|
|
at the same level as libpng.
|
|
|
|
If your system already has a preinstalled zlib 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-1.2.11beta3" 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:
|
|
|
|
.. (the parent directory)
|
|
libpng (this directory)
|
|
INSTALL (this file)
|
|
README
|
|
*.h
|
|
*.c
|
|
contrib
|
|
gregbook
|
|
pngminus
|
|
pngsuite
|
|
visupng
|
|
projects
|
|
beos
|
|
c5builder (Borland)
|
|
visualc6 (msvc)
|
|
netware.txt
|
|
wince.txt
|
|
scripts
|
|
makefile.*
|
|
pngtest.png
|
|
etc.
|
|
zlib
|
|
README
|
|
*.h
|
|
*.c
|
|
contrib
|
|
etc.
|
|
|
|
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 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
|
|
build libpng for Netware or Beos as instructed in projects\netware.txt
|
|
or projects\beos.
|
|
|
|
Else enter the zlib directory and follow the instructions in zlib/README,
|
|
then come back here and run "configure" or 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.msc makefile
|
|
UNIX example: cp scripts/makefile.std makefile
|
|
|
|
Read the makefile to see if you need to change any source or
|
|
target directories to match your preferences.
|
|
|
|
Then read pngconf.h to see if you want to make any configuration
|
|
changes.
|
|
|
|
Then just run "make" which will create the libpng library in
|
|
this directory and "make test" which will 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 contrib/pngsuite/*.png" 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".
|
|
|
|
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.
|
|
|
|
Further information can be found in the README and libpng.txt
|
|
files, in the individual makefiles, in png.h, and the manual pages
|
|
libpng.3 and png.5.

Using the ./configure script -- 16 December 2002.
|
|
=================================================
|
|
|
|
|
|
The ./configure script should work compatibly with what scripts/makefile.*
|
|
did, however there are some options you need to add to configure explicitly,
|
|
which previously was done semi-automatically (if you didn't edit
|
|
scripts/makefile.* yourself, that is)
|
|
|
|
|
|
CFLAGS="-Wall -O3 -funroll-loops \
|
|
-malign-loops=2 -malign-functions=2" ./configure --prefix=/usr/include \
|
|
--with-pkgconfigdir=/usr/lib/pkgconfig --includedir=/usr/include
|
|
|
|
You can alternatively specify --includedir=/usr/include, /usr/local/include,
|
|
/usr/include/png12, or whatever.
