including math.h is step 1 but you need to link the libs in aswell so add a 
 -lm to the linker options ( libm is not included by default !) including 
libm requires libc in most (all ?) cases so you will have to add a -lc aswell 
and then for gcc to do its magic cleanups add -L/PATH/TO/GCC/LIB -lgcc .

you also need to statically link the libs , so add -static to the ld flags
