C++ – Error: undefined reference to `sqlite3_open’


I'm trying to get started with the C++ API for SQLite.

#include <iostream>
#include <sqlite3.h>

using namespace std;

int main()
    sqlite3 *db;
    if (sqlite3_open("ex1.db", &db) == SQLITE_OK)
        cout << "Opened db successfully\n";
        cout << "Failed to open db\n";

    return 0;

Compiling this using the command "g++ main.cpp" gives the following error:

/tmp/ccu8sv4b.o: In function `main':
main.cpp:(.text+0x64): undefined reference to `sqlite3_open'
collect2: ld returned 1 exit status

What could have gone wrong? Hasn't sqlite3 properly installed in the server I'm compiling this in?

Best Solution

You need to link the sqlite3 library along with your program:

g++ main.cpp -lsqlite3
