你好。
首先，我很抱歉我的 ita-english。
我想将 gwan 与 aerospike 一起使用，但是在运行 servlet 时...问题。我从 aerospike 的这个 example.c 开始。在文件 example.c 中，我输入了 gwan.h，这是输出 ./gwan：
loading
hello.cs: to use .cs scripts, install C#..
hello.lua: to use .lua scripts, install Lua
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Linking example.c: undefined symbol: g_namespace
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To run G-WAN, you must fix the error(s) or remove this Servlet.
在example.c里面：
#include "gwan.h"
#include <stdbool.h>
#include <stddef.h>
#include <stdint.h>
#include <stdlib.h>
#include <aerospike/aerospike.h>

#include <aerospike/as_record.h>

如何将 aerospike 与 gwan 连接起来？谢谢
