Olimex Eclipse package, how add the right include folder??

Hi there,

i got some problems with eclipse.

Programming and debugging works fine, but i need math.h and cant add them the right way.

How can i setup the include folder to C:\gccfd\yagarto\arm-elf\include ??

Dont found any setup, right project properties, i add them there via

“add external include path” but they arent working, anyone could help me?

Would be great!
