xz_test is a simple C++-wrapper for xz utils, based on the sample programs from xz.
Add all files from src/xz and log.hpp to your source files. Then you can use
xz::compress( std::istream& istream, std::ostream& ostream ), which is based on 01_compress_easy.c
and
xz::decompress( std::istream& istream, std::ostream& ostream ) which is based on 02_decompress.c
To build 64 Bit static libs for Linux, Mac and Windows, just run the corresponding build script from the scripts folder. Note: The Windows build script builds MT and MD libs.
In build/qmake are two sample projects, which use xz::compress and xz::decompress with std::cin and std::cout. Note: These are linked with static CRT (MT) under Windows.
In testing/roundtrip_test is a Qt based unit test, which tests xz::compress and xz::decompress with std::strings and files. Note: These are linked with dynamic CRT (MD) under Windows.
