make:*** [Lab1] Error 1

Question

I already read everything Make: *** [] Error 1 and I am returning a 0 in my main method.

I've tried switching up parsers, but that doesn't work either. I've tried the internal build, that doesn't work (and even if it did I want to work with makefile's).

Here's an example of the error being given. I believe this is what's preventing me from creating the binary files which is a must have in order to run my app.

Here's the console bit. I did a refresh and then build.

As you can see from the image, Lab1 has no Binaries and it's showing the make error.

Solution found thanks to guys commenting

I'm including this code as reference to the comments to this question.

/*
 * Token.h

 */
#pragma once

class Token {

public:
    Token();
    virtual ~Token();

    enum TOKEN_TYPE {START, MIDDLE, END, ERROR};
    /**
     * @pre processToken must be ran first!
     */
    virtual Token getNextToken(char*);
    virtual bool processToken(char*);

};

/* * Token.cpp * * Created on: Sep 12, 2013 * Author: cam */

#include "Token.h"

Token::Token() {

}

Token::~Token() {

}

Token Token::getNextToken(char* buff) {

}

bool Token::processToken(char * buff) {

}

Answer 1

Ultimately I wasn't including two virtual method definitions in my base class. While this got it to compile, I'm curious to know why this is necessary as they are defined as virtual.
