Actually this function is workaround.
because of undefined reference error

/opt/toolchains/arm-2008q3/bin/../lib/gcc/arm-none-linux-gnueabi/4.3.2/libgcc.a(_dvmd_lnx.o):
In function `__aeabi_ldiv0':
(.text+0x8): undefined reference to `raise'

I want to solve it but can't find the reason yet.
How i can fix this problem?

thanks
