| 2 | Installing libpng version 1.0.1 March 15, 1998 | |
| 3 | ||
| 4 | Before installing libpng, you must first install zlib. zlib | |
| 5 | can usually be found wherever you got libpng. zlib can be | |
| 6 | placed in another directory, at the same level as libpng. | |
| 7 | Note that your system might already have a preinstalled | |
| 8 | zlib, but you will still need to have access to the | |
| 9 | zlib.h and zconf.h include files that correspond to the | |
| 10 | version of zlib that's installed. | |
| 11 | ||
| 12 | You can rename the directories that you downloaded (they | |
| 13 | might be called "libpng-1.0.1 or "lpng100" and "zlib-1.1.1" | |
| 14 | or "zlib111") so that you have directories called "zlib" and "libpng". | |
| 15 | ||
| 16 | Your directory structure should look like this: | |
| 17 | ||
| 18 | .. (the parent directory) | |
| 19 | libpng (this directory) | |
| 20 | INSTALL (this file) | |
| 21 | README | |
| 22 | *.h | |
| 23 | *.c | |
| 24 | scripts | |
| 25 | makefile.* | |
| 26 | pngtest.png | |
| 27 | etc. | |
| 28 | zlib | |
| 29 | README | |
| 30 | *.h | |
| 31 | *.c | |
| 32 | contrib | |
| 33 | etc. | |
| 34 | ||
| 35 | First enter the zlib directory and follow the instructions | |
| 36 | in zlib/README. Then come back here and choose the | |
| 37 | appropriate makefile.sys in the scripts directory. | |
| 38 | The files that are presently available in the scripts directory | |
| 39 | include | |
| 40 | ||
| 41 | descrip.mms => VMS makefile for MMS or MMK | |
| 42 | makefile.std => Generic UNIX makefile | |
| 43 | makefile.knr => Archaic UNIX Makefile that converts files with ansi2knr | |
| 44 | makefile.dec => DEC Alpha UNIX makefile | |
| 45 | makefile.sgi => Silicon Graphics IRIX makefile | |
| 46 | makefile.sun => Sun makefile | |
| 47 | makefile.s2x => Solaris 2.X makefile (gcc, creates libpng.so.2.1.0) | |
| 48 | makefile.lnx => Linux/ELF makefile (gcc, creates libpng.so.2.1.0) | |
| 49 | makefile.mip => MIPS makefile | |
| 50 | makefile.aco => Acorn makefile | |
| 51 | makefile.ama => Amiga makefile | |
| 52 | smakefile.ppc => AMIGA smakefile for SAS C V6.58/7.00 PPC compiler | |
| 53 | (Requires SCOPTIONS, copied from scripts/SCOPTIONS.ppc) | |
| 54 | makefile.atr => Atari makefile | |
| 55 | makefile.bor => Borland makefile | |
| 56 | build.bat => MS-DOS batch file for Borland compiler | |
| 57 | makefile.dj2 => DJGPP 2 makefile | |
| 58 | makefile.msc => Microsoft C makefile | |
| 59 | makefile.tc3 => Turbo C 3.0 makefile | |
| 60 | makefile.os2 => OS/2 Makefile (gcc and emx, requires pngos2.def) | |
| 61 | pngos2.def => OS/2 module definition file used by makefile.os2 | |
| 62 | makefile.wat => Watcom 10a+ Makefile, 32-bit flat memory model | |
| 63 | makevms.com => VMS build script | |
| 64 | ||
| 65 | Copy the file (or files) that you need from the | |
| 66 | scripts directory into this directory, for example | |
| 67 | ||
| 68 | MSDOS example: copy scripts\makefile.msd makefile | |
| 69 | UNIX example: cp scripts/makefile.std makefile | |
| 70 | ||
| 71 | Read the makefile to see if you need to change any source or | |
| 72 | target directories to match your preferences. | |
| 73 | ||
| 74 | Then read pngconf.h to see if you want to make any configuration | |
| 75 | changes. | |
| 76 | ||
| 77 | Then just run "make test" which will create the libpng library in | |
| 78 | this directory and run a quick test that reads the "pngtest.png" | |
| 79 | file and writes a "pngout.png" file that should be identical to it. | |
| 80 | ||
| 81 | Most of the makefiles will allow you to run "make install" to | |
| 82 | put the library in its final resting place (if you want to | |
| 83 | do that, run "make install" in the zlib directory first if necessary). | |
| 84 | ||
| 85 | Further information can be found in the README and libpng.txt | |
| 86 | files, in the individual makefiles, and in png.h, and the manual | |
| 87 | pages libpng.3 and png.5. |
