[Linker] error undefined...
This is my first time writing an openGL file. Im trying to make a Tetris Game using openGL but when i try to compile & run i get a bunch of linker errors. now Im not sure which packages I need. I have "freeglut", "glut", "glaux", "glui", "openGlut", and all of the basic packages. I'm really stumped here and could use some help. Here is the program so far it is not complete but it should run but it doesnt due to the linker errors............................
