# ip2region xdb lua c 扩展查询客户端实现
# 版本兼容
该实现兼容 lua `5.1`，`5.2`，`5.3`, `5.4`
# 编译安装
通过如下方式来编译安装该扩展：
### 默认编译
通过如下方式来编译安装默认的 `Lua5.4` 版本的扩展：
```bash
# cd 到 lua_c binding 的根目录
make
sudo make install
```
备注：Makefile 里面的 `LuaVersion` 变量代表你本地环境的 lua 的版本，默认为 5.4，如果你的版本不是 5.4，记得先修改为和你本地 lua 版本一致的版本号。
### 指定 Lua 版本
通过如下的 `LuaVersion` 参数指定 Lua 版本编译，例如：`5.1` / `5.2` / `5.3` / `5.4`
```bash
# cd 到 lua_c binding 的根目录
# 例如，编译 5.1 版本兼容的扩展
make LuaVersion=5.1
sudo make install
```
# 使用方式
