2.5K

It puts up a message box

Although, for DOS apps you can cheat because a .COM file doesn't need to have any of the extra information that an .EXE needs to be loaded properly (.com files are a maximum of 64K, and always loaded into the same memory location).

what project settings do you have? I have release, libs only user32.lib, CRT as dll, custom entry point:

void MyMain()
{
  MessageBoxA(blabla);
}

and no header files, I declared MessageBoxA manually...
optimized for size (that won't do anything), the strings are both "" (saves 4k), subsystem windows...

any other things?

[parksie]

Simple method

Redeclare the CRT entry-point:

int _mainCRTStartup() {
    MessageBoxA(NULL, "Hello", "Random", 0);

    return 0;
}

That doesn't even need the CRT at all

[CornedBee]

I did that. Well, I gave my function another name, but I set it as the entry point of my application.

Maybe VC++ 5 creates smaller apps than VC++ 6 ?

[parksie]

Hmm. Try using the "Ignore standard libraries" option.

[CornedBee]

nope, didn't change it. Do you have the project somewhere?

[parksie]

Here it is

[CornedBee]

thanks. I just managed to nearly block a Athlon 600 MHz with integer operations and a damn lot of function calls. I'll try to figure out how many exactly.

[parksie]

Impressive

Oh yeah, and the fact that I wrote that in pure C probably had something to do with it

[CornedBee]

Hey, that could be it.
I have a little problem:

int fib(int n)
{
	if(n == 0 || n == 1)
		return 1;
	return fib(n-1) + fib(n-2);
}

Can you think of a formula how often this thing is called for any number n?
Basically, it's 2^n, but there is this if thing...

[CornedBee]

Hmm...
If I compile your project on my pc with VC++ 6.0 it creates a 16k exe...

[parksie]

1 - I'm not familiar with Big-O notation so can't help you here

2 - Try adding this to the linker options: /OPT:NOWIN98

[CornedBee]

too late. Loading your project somehow killed my VC++, the menu bar is missing
This is the same error some others here experienced. I'm off looking at the microsoft homepage for a solution...

[parksie]

Hee hee.

Makefiles aren't so bad

[CornedBee]

I uninstalled VC++, only to find that there is a solution without reinstalling it. Worst is, I can't find my installation CD now !!!
I DON'T HAVE VC++ AT THE MOMENT

[parksie]

Why do you need it? Just pick another compiler

What VC++ specific features are you using?

[parksie]

Borland

(supports MFC, btw )

I've never had code completion for C++, and it didn't hurt me
