    Weird compile error "(.text+0x32): undefined reference to `cubeByReference'"

    I get this strange error compiling this program. I think there was a compiler parameter that fixed this but it's been years since I've used C. Does anyone know? I'm using Ubuntu Linux.

    Code:
    #include <stdio.h>
    
    void cybeByReference( int * );
    
    int main()
    {
    	int number = 5;
    
    	printf( "The original value of number is %d", number );
    	cubeByReference( &number );
    	printf( "\nThe new value of number is %d\n", number );
    
    	return 0;
    }
    
    
    void cybeByReference( int *nPtr )
    {
    	*nPtr = *nPtr * *nPtr * *nPtr;
    }


    Code:
    eugene@eugene-laptop:~/cfiles$ cc -Wall -pedantic fig07_07.c
    fig07_07.c: In function ‘main’:
    fig07_07.c:10: warning: implicit declaration of function ‘cubeByReference’
    /tmp/cck2bZ1N.o: In function `main':
    fig07_07.c:(.text+0x32): undefined reference to `cubeByReference'
    collect2: ld returned 1 exit status

    Surprisingly, there is no compiler parameter for "I can't spell".

    Good eye. But that didn't solve the error message.

    I assumed you would change both the cybe's to cube's, so I didn't color them both in; but you did also misspell the function name down below.

    Ahh, you're right. Thanks

    There really is a special parameter I swear!
