Errors on opengl code with c++

[jo45ng]

Hi everyone, I urgently need help on this opengl code I compiled with c++. It gives errors:


Error E2040 opengl_simple.cpp 1: Declaration terminated incorrectly
Error E2206 opengl_simple.cpp 5: Illegal character '#' (0x23)
Error E2206 opengl_simple.cpp 22: Illegal character '#' (0x23)
Error E2323 opengl_simple.cpp 44: Illegal number suffix
*** 4 errors in Compile ***

#include <GL/glut.g>

Is there actually any such file as this?

[hanst99]

[ code ] [ /code ] tags please.

And that's pretty weird. Did you really use the right compiler? The compiler complains the number sign is illegal, which it isn't. Also, it thinks in line 1 there is a declaration (which it isn't either)

[Moschops]

This line

glVertex2f(0.5, -0.5)

is missing a terminating semi-colon, but once that's fixed and the included header actually exists, and the numbers are removed from the beginning of every line, it happily compiles and runs as far as throwing up on itself because glutCreateWindow is called without first calling glutInit.

Whatever the OP is compiling, it's not the code posted.
