Installing libpng version 1.2.1 - December 12, 2001 |
|
|
|
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.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-1.2.1" or "lpng109" and "zlib-1.1.3" |
|
or "zlib113") 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 |
|
msvctest |
|
pngminus |
|
pngsuite |
|
visupng |
|
projects |
|
beos |
|
borland |
|
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\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.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 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). |
|
|
|
Further information can be found in the README and libpng.txt |
|
files, in the individual makefiles, in png.h, in the README files in |
|
subdirectories of the LIB directory, and the manual pages libpng.3 and png.5.
