下载LZ4库源码:
git clone git@gitee.com:epson/lz4.git
打开build\VS2019\LZ4.sln
生成动态库,注意选择需要的版本(debug/release)和平台(x64/x86)
?需要用到的 lz4.dll 和 lz4.lib
以及头文件
?
简单测试:
#include <iostream>
#include "include/lz4/lz4.h"
#ifndef _DEBUG
#else
#ifdef _WIN64
#pragma comment (lib,"lib/x64/Debug/lz4.lib")
#else
#pragma comment (lib,"lib/x86/Debug/lz4.lib")
#endif // _WIN64
#endif
int main()
{
const char * src = "Hello World!";
int src_size = (int)strlen(src) + 1;
int max_dst_size = LZ4_compressBound(src_size);
char* dst = new char[max_dst_size];
int dst_size = LZ4_compress_default(src, dst, src_size, max_dst_size);
int max_src_ex_size = dst_size * 4;
char* src_ex = new char[max_src_ex_size];
int src_ex_size = LZ4_decompress_safe(dst, src_ex, dst_size, max_src_ex_size);
delete[] dst;
dst = NULL;
delete[] src_ex;
src_ex = NULL;
}
