Compiling C and sqlite3

Question

I'm having some trouble incorporating sqlite3 into a program I'm writing. I've been scouring the internet over the past few days attempting to find a solution. I'm using the MinGW compiler and have already tried:

Ensuring the C:\MinGW\bin directory is included in both the user and system environment Path variables with no spaces and separated with a semi-colon
Using the command prompt and entering "C:\MinGW\bin\gcc shell.c sqlite3.c -lpthread -ldl" in the same directory of all related files which returns the result "c:/mingw/bin/../lib/gcc/mingw32/5.3.0/../../../../mingw32/bin/ld.exe: cannot find -ldl collect2.exe: error: ld returned 1 exit status"
Fresh install of MinGW and eclipse

If it helps this is the code I'm testing this with, I can't get the includes to show up as code but they are all in carets in order, iostream, stdio.h, and sqlite3.h It returns the error "fatal error: sqlite3.h: No such file or directory". I have all of the include files in the same directory as the .cpp source as well.

int main(int argc, char* argv[])
{
    sqlite3 *db;
    char *zErrMsg = 0;
    int rc;
    rc = sqlite3_open("text.db", &db);
    return 0;
}

#include <stdio.h>
#include "sqlite3.h"

int main(int argc, char* argv[])
{
    sqlite3 *db;
    char *zErrMsg = 0;
    int rc;
    rc = sqlite3_open("text.db", &db);
    return 0;
}

Compile and test result:
