sqlite 데이터베이스에 링크하려는 C++ 광고를 처음 사용했습니다. 자습서를 따르고 있는데 sqlite3_open 오류가 발생했습니다. 정의되지 않은 참조입니다. 내가 뭘 잘못하고 있니?C++ QTCreator 5.0 SQLite3_Open 정의되지 않음 참조
#include "database.h"
#include<stdio.h>
#include<sqlite3.h>
#include<stdlib.h>
database::database()
{
}
int database::test()
{
int retval;
// A prepered statement for fetching tables
sqlite3_stmt *stmt;
// Create a handle for database connection, create a pointer to sqlite3
sqlite3 *handle;
// try to create the database. If it doesnt exist, it would be created
// pass a pointer to the pointer to sqlite3, in short sqlite3**
retval = sqlite3_open("CC.sqlite",&handle);
// If connection failed, handle returns NULL
if(retval)
{
printf("Database connection failed\n");
return -1;
}
printf("Connection successful\n");
return 1;
}
