Installing libpng version 1.0.1 March 9, 1998 |
|
|
|
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-1.0.1 or "lpng100" and "zlib-1.1.1" |
|
or "zlib111") 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 |
|
scripts |
|
makefile.* |
|
pngtest.png |
|
etc. |
|
zlib |
|
README |
|
*.h |
|
*.c |
|
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. |
|
The files that are presently available in the scripts directory |
|
include |
|
|
|
descrip.mms => VMS makefile for MMS or MMK |
|
makefile.std => Generic UNIX makefile |
|
makefile.knr => Archaic UNIX Makefile that converts files with ansi2knr |
|
makefile.dec => DEC Alpha UNIX makefile |
|
makefile.sgi => Silicon Graphics IRIX makefile |
|
makefile.sun => Sun makefile |
|
makefile.s2x => Solaris 2.X makefile (gcc, creates libpng.so.2.1.0) |
|
makefile.lnx => Linux/ELF makefile (gcc, creates libpng.so.2.1.0) |
|
makefile.mip => MIPS makefile |
|
makefile.aco => Acorn makefile |
|
makefile.ama => Amiga makefile |
|
smakefile.ppc => AMIGA smakefile for SAS C V6.58/7.00 PPC compiler |
|
(Requires SCOPTIONS, copied from scripts/SCOPTIONS.ppc) |
|
makefile.atr => Atari makefile |
|
makefile.bor => Borland makefile |
|
build.bat => MS-DOS batch file for Borland compiler |
|
makefile.dj2 => DJGPP 2 makefile |
|
makefile.msc => Microsoft C makefile |
|
makefile.tc3 => Turbo C 3.0 makefile |
|
makefile.os2 => OS/2 Makefile (gcc and emx, requires pngos2.def) |
|
pngos2.def => OS/2 module definition file used by makefile.os2 |
|
makefile.wat => Watcom 10a+ Makefile, 32-bit flat memory model |
|
makevms.com => VMS build script |
|
|
|
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). |
|
|
|
Further information can be found in the README and libpng.txt |
|
files, in the individual makefiles, and in png.h, and the manual |
|
pages libpng.3 and png.5.
