ubuntu sqlite3源码编译

1、首先从SQLite Download Page网站下载最新sqlite3源码，

2、选择sqlite3.c和sqlite3.h,sqlite3ext.h加载到工程中。

3、编写测试main.c函数：

#include 
#include 
#include "sqlite3.h"

int main()
{
    sqlite3 *db;
    int nResult = sqlite3_open("test.db", &db);
    if(nResult == SQLITE_OK)
    {
        printf("open successn");
    }
    else
    {
        printf("open failn");
    }

    return 0;
}

4、编写命令行命令：gcc -o main main.c sqlite3.c -lpthread -ldl -lm

如果不加上-lpthread -ldl -lm，则会报错，报错信息如下：
