Can´t find the gl_FragColor option

Hello there,

i want to setup a Fragment Shader, but i don´t find the variable “gl_FragColor”. If i try to compile my code the
compiler could not find this var.

Can anyone give me a hint which header i need to include.



gl_FragColor is part of the bulitin GL Shading language variables – there is no header to include this. Maybe reading
GLSL intro might help explain more about the GL shaders.
