glRotate3f doesn't work right!

Whenever I want to rotate something with:

glRotate3f(angle, 0, 1, 0);

or something similar, the angle never looks
right when I compile the program.
for example if the angle is set to 90deg
it is nowhere close to the real angle.
why?

What do you mean by ‘never looks right when compiling’? You get a compiler warning or what?

Try using a variable angle, and increase it when you press a key or similar, then you can see how the object behave when the rotation angle increases. Or maybe you have done other transformations before that affects the result.

Remember that it is adviseable not to rotate the same matrix several times. If you want a rotating cube, it is better to load a new matrix everypass and rotate it with an incremental variable than incremental rotating the matrix itself.
