#241 Undefined symbol fghJoystickRawRead in libglut.so.3.10.0

[Alexander Pyhalov]

The issue is that fghJoystickRawRead() function is declared as static void in freeglut-3.0.0/src/fg_joystick.c and later is used in freeglut-3.0.0/src/x11/fg_joystick_x11.c. But
a) there's no declaration of fghJoystickRawRead() in fg_joystick_x11.c;
b) it's invisible here, as it's local to fg_joystick.o.
The following patch fixes the issue but side effect is that fghJoystickRawRead() symbol is exported from libglut.so.

You don't need to remove the static modifier in fg_joystick.c, which prevents te function from being exported. All you should need is to add "static" to the foward declartion you made in fg_joystick_x11.c

[Diederick C. Niehorster]

So to be clear (as i can't test this), the solution is to add:
static void fghJoystickRawRead( SFG_Joystick joy, int buttons, float* axes );

to fg_joystick_x11.c?

Cheers,
Dee

This should no longer be an issue. While trying to fix the freeglut build on freebsd I changed this function to not be static, and moved its declaration to fg_internal.h.
