# lsqlite
sqlite3的lua封装库！
# 依赖
- [lua](https://github.com/xiyoo0812/lua.git)5.2以上
- [luakit](https://github.com/xiyoo0812/luakit.git)一个luabind库
- 项目路径如下
|--proj
|--lua
|--lsqlite
|--luakit
# 编译
- msvc: 准备好lua依赖库并放到指定位置，将proj文件加到sln后编译。
- linux: 准备好lua依赖库并放到指定位置，执行make -f lmdb.mak
# 注意事项
- mimalloc: 参考[quanta](https://github.com/xiyoo0812/quanta.git)使用，不用则在工程文件中注释
# 用法
