ok i'm brand new with C++, so i really don't know anything at all.

i'm studying a book on it, and for a while i have been able to get by with just including iostream and string

(Toggle Plain Text)

#include <iostream>
#include <string>

using namespace std;

int main()
{
cout << "whatever" << endl;
return 0;
}

this USED to work without errors, but for some reason suddenly this format gives me the error that suggests "Did you forget to add '#include "stdafx.h"' to your source?"

i never had to #include <stdafx.h> before, and indeed my code WILL work if i do include it, but what i want to know is why suddenly i'm obligated to use it? it's just a pain to me.

Did you change compilers? Did you change any settings on your compiler? Things don't just stop working without there being a trigger.

DaWei · Jun 9th, 2006, 10:50 PM

You just need to change your compiler settings to not precompile headers. When you set up your project, set up an "empty" project and you'll automatically get the precompiled headers off. It's an MS thangy. At this point, you can just go into compiler options and turn them off. If you have problems finding where, just post back and I'll give you a trail.

i see, i found the empty project. i guess empty project is the best way to go then.

Or switch to code::blocks...

bl00dninja · Jun 10th, 2006, 1:35 AM

code::blocks is a great free IDE, but why would you decide to quit using an industrial-strength application development tool to use a shareware one instead?

i have both, i ususally use MS VS. that doesn't mean the other is bad, but would you try to race a stock car with an automatic transmission just because you didn't want to learn to drive a stick?

Harakim · Jun 10th, 2006, 2:00 AM

I guess I pretty much have to try code::blocks now since so many people are talking about it.

Could people do me a favor and not suggest switching IDEs anytime someone doesn't know some nuance to the one they're currently using? Especially when another poster has addressed the issue... We've had a few threads about "I don't know how to do this or that" and people seem to jump at changing IDEs instead of letting the OP learn how to use what they've already got.

Sorry for sounding upset, but this has started bugging me...

Indeed. No IDE is perfect (and, even if it was, one mans perfection is another mans horror story) and it is usually easier to tweak most IDEs to solve a problem than it is to install and learn to use a new one.

I suppose, when someone has a problem with settings of code::blocks, that they will be inundated with suggestions to install some other IDE.

splinter9x · Jun 10th, 2006, 5:08 AM

I have tried code::blocks and Dev-C++ and I personally prefer, even though it seems as if it is not being developed anymore I still like Dev-C++. But you guys have a point. Switching IDE's is no way to fix a problem. Just figure out how to fix the problem in the IDE that you are using.
