Apart from fast compression it also useful + for situations where you want to use pre-compressed data files (which + must have been compressed with LZO1X-999). + + miniLZO consists of one C source file and two header files: + minilzo.c + minilzo.h + lzoconf.h + + To use miniLZO just copy these files into your source directory, add + minilzo.c to your Makefile and #include minilzo.h from your program. + Note: you also must distribute this file (`README.LZO') with your project. + + minilzo.o compiles to about 6 kB (using gcc or Visual C on a i386), and + the sources are about 14 kB when packed with zip - so there's no more + excuse that your application doesn't support data compression :-) + + For more information, documentation, example programs and other support + files (like Makefiles and build scripts) please download the full LZO + package from + http://www.oberhumer.com/opensource/lzo/ + + Have fun, + Markus + + + P.S. minilzo.c is generated automatically from the LZO sources and + therefore functionality is completely identical + + + Appendix A: building miniLZO + ---------------------------- + miniLZO is written such a way that it should compile and run + out-of-the-box on most machines. + + If you are running on a very unusual architecture and lzo_init() fails then + you should first recompile with `-DLZO_DEBUG' to see what causes the failure. + The most probable case is something like `sizeof(char *) != sizeof(long)'. + After identifying the problem you can compile by adding some defines + like `-DSIZEOF_CHAR_P=8' to your Makefile. + + The best solution is (of course) using Autoconf - if your project uses + Autoconf anyway just add `-DMINILZO_HAVE_CONFIG_H' to your compiler + flags when compiling minilzo.c.
