Oh I am a big turnip!
Ok heres the code:
/* Using the standard output for fprintf */
#include <stdio.h>
#include <stdlib.h>
/* Use glew.h instead of gl.h to get all the GL prototypes declared */
#include <glew.h>
/* Using the GLUT library for the base windowing setup */
#include <glut.h>
/* ADD GLOBAL VARIABLES HERE LATER */
int init_resources(void)
{
/* FILLED IN LATER */
return 1;
}
void onDisplay()
{
/* FILLED IN LATER */
}
void free_resources()
{
/* FILLED IN LATER */
}
int main(int argc, char* argv[])
{
/* Glut-related initialising functions */
glutInit(&argc, argv);
glutInitContextVersion(2,0);
glutInitDisplayMode(GLUT_RGBA|GLUT_DOUBLE|GLUT_DEPTH);
glutInitWindowSize(640, 480);
glutCreateWindow("My First Triangle");
/* Extension wrangler initialising */
GLenum glew_status = glewInit();
if (glew_status != GLEW_OK)
{
fprintf(stderr, "Error: %s\n", glewGetErrorString(glew_status));
return EXIT_FAILURE;
}
/* When all init functions run without errors,
the program can initialise the resources */
if (1 == init_resources())
{
/* We can display it if everything goes OK */
glutDisplayFunc(onDisplay);
glutMainLoop();
}
/* If the program exits in the usual way,
free resources and exit with a success */
free_resources();
return EXIT_SUCCESS;
}
and here are the errors: http://imgur.com/H2R00O9
(isnt there a way to just COPY AND PASTE the darn text from the build messages screen????????)
I installed glut as like the readme.txt file said:
* Put the .dll in system32 directory
* put the .h file in "CodeBlocks\MinGW\include" and "CodeBlocks\MinGW\include\GL"
* put the .lib "CodeBlocks\MinGW\lib"
Restarted program and the code, and it gives those errors...
Ok heres the build log:

What's this mean and how can it be fixed?
I also now have another query in relation to this website:
http://en.wikibooks.org/wiki/OpenGL_Programming#The_basics_arc
From an example page i found a link to the source code for the examples and decided to download it. I was sure that if ever anything was ever even remotely possible to fluke and work, it would be with fully working examples which had been set up by an expert that I could just open and run.
FYI, the download link page is here: https://gitorious.org/wikibooks-opengl/modern-tutorials/source/90bf72991caf34ea6cdbed044a9616b7bbdf2d0f:

glut (freeglut is installed), glew is installed, GLM is installed now as well. What else needs to be installed?
For the record I have not edited the code at all. I literally just opened codeblocks, opened the .cpp file and ran it. No adjustments.
Can anyone confirm that any of the code from the above site works at all? I'm starting to think its actually not me now...
If anyone can make any of this code run, please advise what else is needed to be installed in codeblocks...
