comment Why does glGetString returns a NULL string
@NicolBolas Yup. Although I have no idea why. Maybe it uses some default values in case when these values are specified as 0.

comment Why does glGetString returns a NULL string
Problem was not with glfwOpenWindow arguments. It was with glfw installation. I installed it again from the ubuntu repositories instead of tar ball installation, everything worked smoothly.

comment Why does glGetString returns a NULL string
@Grieverheart You were right. Thanks a lot! Instead of building and installing directly from the tar ball, I installed it from ubuntu's repository. That worked. I have no idea why.

comment Why does glGetString returns a NULL string
as suggested by the Edit, there is some problem with glfwopenwindow command. The arguments given to this function are valid. I checked the documentation for that. If you have any other ideas why this error might be occurring please do tell me.

@Grieverheart g++ triangle.cpp -o main -lGLEW -lglfw -lGLU -lGL -lm this is the command I use to compile my program. I will try using glGetError. That's a good idea.
