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
|
1998-04-21 20:03:57 +00:00
|
|
|
might be called "libpng-%VER% or "lpng100" and "zlib-1.1.1"
|
1998-03-07 12:06:55 +00:00
|
|
|
or "zlib111") so that you have directories called "zlib" and "libpng".
|
|
|
|
|
|
|
|
|
|
Your directory structure should look like this:
|
|
|
|
|
|
|
|
|
|
.. (the parent directory)
|
|
|
|
|
libpng (this directory)

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
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
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).
|
|
|
|
|
|

|

|
|
|
|
|
files, in the individual makefiles, and in png.h, and the manual
|
|
|
|
|
pages libpng.3 and png.5.
