This is a shared library for Android, iOS, OSX, Windows, Linux and webGL to decompress 7z (7zip) files and to compress/decompress zip/gzip (.zip/.gz), LZ4 (.lz4), brotli (.br), fastLZ files and buffers. ZIP plugin: iOS/tvOS compilation may require to add the -lz linking flag at Build Settings-> Linking- > Other Linker flags on xcode. webGL for flz,lzma & lz4 supports buffers compression/decompression only. Brotli supports buffer decompression. webGL for zip supports all functions except those that require file system operations. 7ZIP section: The library serves the scope to have fast decompression of 7z files and compress/decompress lzma files and buffers. - The library does 7z decompression and not 7z compression. Compression of lzma alone files is supported. Passwords are not supported. - It is about 2.5x times faster then using a c# implementation for 7z decompression. - You can extract a single file out of the 7z archive. - If you intend to decompress large files it would be better to use the largeFiles flag.(consumes less ram) - You can extract the contents of the 7z file keeping its folder structure. - Ability to get the filenames and file sizes of files in a 7z archive. - get progress of extraction when the 7zip archive has multiple files. - get byte level progress of 7z decompression (single or multiple files). - get byte level progress of lzma compression/decompression. - Ability to encode/decode to/from .lzma alone format. - Ability to decode a specific file in a 7z archive to a byte buffer. - Ability to decode/encode a byte buffer to/from the lzma alone format. - Ability to cancel the decompression when the 7z archive has multiple entries.

LZMA 压缩及解压缩算法的 C 源代码，包括了编码器及解码器的 C 源码 ANSI-C LZMA 解压缩代码是从原始的 C 源代码转换到 C。并简化和优化了代码的大校但它依然和 7-Zip 的 LZMA 完全兼容。LZMA 的压缩速度：在 1 GHz 的处理器上能达到 500 KB/秒。

mingw32下载gdb失败可离线安装，GDB是GNU开源组织发布的一个强大的UNIX(不仅限于UNIX)下的C/C++程序调试工具。它搭配MINGW使用，可以使用户完成整个C/C+程序的编译和运行工作。有了GDB，用户可以在调试本地的C程序时不需要第三方C/C++工具

Clover BootLoader 黑苹果引导

解决安装mysql时报，libraries: libaio.so.1这个内容缺失

Linux下编译缺少liblzo2.so.2 ，liblzma.so.5.2.4等问题，添加对应库到library path就可以了，修改方式： LD_LIBRARY_PATH=xxx，在ubuntu上验证OK

通过Qt5使用LZMA SDK完成C++的7z格式文件压缩和解压缩(源码和可执行文件均包含在内),实现了百分比进度条显示功能。
