Hi everyone. I think i''m going to be hanging around these boards more often. This is my first post though. Here is the scoop. I am 17 now. I have been doing dos programming my whole life. particularly quickbasic and asm programming, but i dabbled in c(DJGPP). I recently waded into windows with some VB6 and BlitzBasic/DarkBasic (I will be suprised if people here even knows the blasphemy that is DarkBasic) ANyways, I really want to use c++ and OpenGL because I am so tired of being limited. So: I downloaded DevC++, OpenGL2, and GLUT and I am very disappointed. So far I have hardly been able to complile ANYTHING. None of the Glut or ogl examples will work. Even the "Hello-world" program that comes with DevC++ wouldnt compile! I don''t have the money for VC++ and im a complete dumbass. What am i going to do!?!?!??!! -= Twisted Matrix =-

here is a nice c++ WIN32 and OpenGL tutorial site:

GameTutorials.com

Use it. The people there are really helpful

EDIT: I don't know much about DevC++ but I do know that you need to include stdio.h and add system("PAUSE"); before return 0;
at the end of your main function hope that helped you

It''s probably because of the settings of the compiler you use. Sorry, but I don''t use DevC++, can''t help any further.

My compiler generates one error message: "does not compile."

#include <stdio.h>#include <stdlib.h>int main { printf("Hello World\n"); printf("This is my first program.");  system("PAUSE"); return 0;}/*C version of Hello World above*/#include <iostream>#include <stdlib.h>using namespace std;int main { cout << "Hello World" << endl; cout << "This is my first program.";  system("PAUSE"); return 0;}//C++ version of Hello World above 

These two programs should work with Dev-C++ or any C/C++ compiler. Also for OpenGL, you need to go the Bloodshed.net site and look for the section on how to setup the library for GL.

Any question feel free to ask

They say DevC++ and MinGW (They come in a package. IDE and c++ compiler), are supposed to be the next best *free* thing to VC++.

Thanks Jeff. No that dosent really help. I seem to be having problems with linking. here are a few average errors for ya...

Looks like an #include problem for me...


My compiler generates one error message: "does not compile."

Granted I have know Idea what Im doing. but "fullscreen.c" has 3 include lines.

#include <windows.h>
#include <GL/glut.h>
#include <stdio.h>

and in glut.h, some libraries appear to already be linked.

/* To disable automatic library usage for GLUT, define GLUT_NO_LIB_PRAGMA
in your compile preprocessor options. */
# if !defined(GLUT_BUILDING_LIB) && !defined(GLUT_NO_LIB_PRAGMA)
# pragma comment (lib, "winmm.lib") /* link with Windows MultiMedia lib */
/* To enable automatic SGI OpenGL for Windows library usage for GLUT,
define GLUT_USE_SGI_OPENGL in your compile preprocessor options. */
# ifdef GLUT_USE_SGI_OPENGL
# pragma comment (lib, "opengl.lib") /* link with SGI OpenGL for Windows lib */
# pragma comment (lib, "glu.lib") /* link with SGI OpenGL Utility lib */
# pragma comment (lib, "glut.lib") /* link with Win32 GLUT for SGI OpenGL lib */
# else
# pragma comment (lib, "opengl32.lib") /* link with Microsoft OpenGL lib */
# pragma comment (lib, "glu32.lib") /* link with Microsoft OpenGL Utility lib */
# pragma comment (lib, "glut32.lib") /* link with Win32 GLUT lib */
# endif
# endif


anyways, how am I supposed to know what files to link to a given program I am running. I mean, All the error I am geting is "undefined referance to blah();" Mabey If i knew every all of the functions in every LIB I could pipoint which file I am not linking or whatever.

I have no idea...
