Thread: OpenGL vs. DirectX ???

Is that because standard C is used ?

#include <stdio>
using namespace std;

Well it doesnt compile correctly with that change but it does compile with a 'c' placed before the stdio

Code:

#include <cstdio>
using namespace std;

But I still get the error when linking:

c:\windows\TEMP\ccDXufgb.o(.text+0x94):tictacto.cp p: undefined reference to `GetStockObject@4'

c:\windows\TEMP\ccDXufgb.o(.text+0x55c):tictacto.c pp: more undefined references to `TextOutA@20' follow

Maybe I havent set up my compiler correctly?

I need a 'compiler for dummies' version.

errrr...

You mean, read the instructions?

No, I pretty much just double clicked the installer and then started compiling. Ya think I mighta missd something?


Thanks for all your help!

I think its time to go read some more about my compiler... LOL!

Maybe I should download GLUT37 and start breaking that too...

#include <stdio> ?!?!

don't you mean #include <iostream>?


**edit***

for those "TextOut" etc. undefined references, are you including <windows.h>?

The help file is a little sparse on it too.

It was the first compiler that I could copy and paste code into and it worked.

I am basically finding code and seeing what I have to do to get it to compile. I would hate to learn enough C++ to write a large program and then have no way of running it because of compiler issues.

Now I need to learn more about compilers...

Ugh... I shoulda done this years ago... It's easier when the brain cells arent all fused together with complacency ... LOL

window.h is included

I added iostream.h

and I still get the errors...

I never said <iostream.h>, i said <iostream> <-notice no ".h"

If you're still having trouble post a zip file with your project as well as what compiler/OS you're using.

Here is the cpp I am trying to get to compile correctly on Dev-C++ (Version 4)

Do you have any homework online?
Perhaps you could throw in a link or two?

I teach medical instrumentation, so the homework I give out probably isn't of any use to you :P

The C++ Programming Language, Third Edition
by Bjarne Stroustrup

This is one of my 2 C++ references that I use all the time (the other being "The C++ Standard Library" by Josuttis). These books are excellent references, although I will admit I haven't used either while learning the language; I don't know how friendly relatively new programmers will find them. I don't think either is aimed at new programmers, actually. They're both books every serious programmer should eventually own, though.

LOL! The code now compiles with those changes, however [seems like there is always a 'however'] now when i go from the compiler to the linker I get this

You can ignore the replies that mention source code changes (although they won't hurt and may well improve your readability/standards compliance). Your code compiles, but doesn't link: this suggests that you don't have or aren't linking the proper libraries. Errors in code or headers will show up as failed compilation, not typically failed linking.

Those all seem to be errors with linking WinAPI libraries; try to find a tutorial or such on compiling Win32 apps with your compiler, it will have to include that info.

be sure to include <windows.h> before any other include's. I have had this cause link errors before.

With the exception of having to change the second

Code:

for(u = blah,blah,blah

to

Code:

for(uu = blah,blah,blah

(because VC doens't allow redefinitions like that.)

it complied and ran fine with VC++ 6
