Question

当我要将sqlite3连接到我的项目mfc DLL时，它导入到c＃。出现错误＆＃39;找到一个或多个多重定义的符号＆＃39;怎么解决这个问题。首先我包括sqlite3.h并添加sqlite3.lib，在我的项目文件夹中使用sqliteBrowser创建一个数据库到我的项目。 Dcode是我的mfc Dll项目和项目路径Dcode.dll F：\ project \ Project \ Dcode \ Dcode \ 然后编写代码

sqlite3 *conn; //connection object

const char *dbname="F:\\project\\ Project \\db.s3db";//destination for DB

 int s=sqlite3_open(dbname,&conn);//allocating memory to the sqlite3 object using sqlite3_open constructors  

if(s==SQLITE_OK)
{                      
 std::cout<<"Opened database successfully\n";
}

然后错误错误115错误LNK1169：找到一个或多个多重定义的符号
