[Plib-users] error compiling plib

[Guy B. <gba...@ct...>]

Hi,
I'm new to plib and I wanted to compile it to use FlightGear, but when
compiling plib I have the messages:
 GLUT_LEFT_BUTTON undeclared (first use this function)
 GLUT_RIGHT_BUTTON undeclared (first use this function)
 GLUT_MIDDLE_BUTTON undeclared (first use this function)
GLUT_WINDOW_WITH etc...
If I want to compile FlightGear, It doesn't find plib!!
What is the problem.
Thank to answear me
