Hello all, I''m having some trouble with the default OpenGL project that Dev-C++ creates for you. It worked properly at first, but then I added a TGA loading routine and a class which I have only designed not implemented yet, and I get the following error: 156 C:\dev\exp_conq\main.cpp ISO C++ forbids declaration of `glClearColor'' with no type Then immediately after that: 156 C:\dev\exp_conq\main.cpp `int glClearColor'' redeclared as different kind of symbol and again: 156 C:\dev\exp_conq\main.cpp initializer list being treated as compound expression 156 C:\dev\exp_conq\main.cpp [Warning] initialization to `int'' from `float'' 156 C:\dev\exp_conq\main.cpp [Warning] argument to `int'' from `float'' The code on line 156 is: glClearColor(0.0f, 0.0f, 0.0f, 0.0f); I can see nothing wrong with the code, especially considering that it worked properly before. ??? I''m hoping that this is just a setting that will fix the problem easily. ^_^ I also have the following headers included: #include <windows.h> #include <stdio.h> #include <gl/gl.h> #include <gl/glu.h> Any ideas? P.S. I''m using Dev-C++ 4.9.8.0

I just thought this other info might be relevant:

The linker is given the argument -lopengl32

And here is the drawing code:


/* OpenGL animation code goes here */

glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
glClear(GL_COLOR_BUFFER_BIT);

glBindTexture(GL_TEXTURE_2D, texture[0]);

glPushMatrix ();
glRotatef (theta, 0.0f, 0.0f, 1.0f);
glBegin (GL_TRIANGLES);
glTexCoord2f(0.0f, 1.0f); glVertex2f (0.0f, 1.0f);
glTexCoord2f(1.0f, 0.0f); glVertex2f (1.0f, 0.0f);
glTexCoord2f(1.0f, 1.0f); glVertex2f (1.0f, 1.0f);
glEnd ();
glPopMatrix ();

SwapBuffers (targetDC);

theta += 1.0f;
Sleep (1);

GCC can be pissed off if you have a C project which you declare as C++, or the other way around.
Or if you mix C with C++ without doing it properly.
