1.安装sqlite3

sudo apt-get install sqlite3;

2.编译的时候出现 

/usr/bin/ld: /tmp/ccopXpY8.o: in function `main':
server.c:(.text+0x3d): undefined reference to `sqlite3_open'
/usr/bin/ld: server.c:(.text+0x50): undefined reference to `sqlite3_errmsg'
collect2: error: ld returned 1 exit status

要在后面加上

 -lsqlite3

例如：

gcc -o server server.c -lsqlite3;

3.如果出现找不到 -lsqlite3错误，就需要下载指令集：

sudo apt-get install libsqlite3-dev;
