FastLZ is distributed using the MIT license, see file LICENSE for details.

FastLZ consists of two files: fastlz.h and fastlz.c. Just add these files to your project in order to use FastLZ. For information on compression and decompression routines, see fastlz.h.

A simple file compressor called 6pack is included as an example on how to use FastLZ. The corresponding decompressor is 6unpack.

To compile using GCC:

gcc -o 6pack 6pack.c fastlz.c gcc -o 6unpack 6unpack.c fastlz.c

To compile using MinGW:

mingw32-gcc -o 6pack 6pack.c fastlz.c mingw32-gcc -o 6unpack 6unpack.c fastlz.c

To compile using Microsoft Visual C++:

cl 6pack.c fastlz.c cl 6unpack.c fastlz.c

To compile using Borland C++:

bcc32 6pack.c fastlz.c bcc32 6unpack.c fastlz.c

To compile using OpenWatcom C/C++:

cl386 6pack.c fastlz.c cl386 6unpack.c fastlz.c

To compile using Intel C++ compiler for Windows:

icl 6pack.c fastlz.c icl 6unpack.c fastlz.c

To compile using Intel C++ compiler for Linux:

icc -o 6pack 6pack.c fastlz.c icc -o 6unpack 6unpack.c fastlz.c

To compile 6pack using LCC-Win32:

lc 6pack.c fastlz.c lc 6unpack.c fastlz.c

To compile 6pack using Pelles C:

pocc 6pack.c pocc 6unpack.c pocc fastlz.c polink 6pack.obj fastlz.obj polink 6unpack.obj fastlz.obj

For speed optimization, always use proper compile flags for optimization options. Typical compiler flags are given below:

• GCC (pre 4.2): -march=pentium -O3 -fomit-frame-pointer -mtune=pentium
• GCC 4.2 or later: -march=pentium -O3 -fomit-frame-pointer -mtune=generic
• Digital Mars C/C++: -o+all -5
• Intel C++ (Windows): /O3 /Qipo
• Intel C++ (Linux): -O2 -march=pentium -mtune=pentium
• Borland C++: -O2 -5
• LCC-Win32: -O
• Pelles C: /O2
