Cann't find Cross Compiler in menuconfig?

[NalaGinrut]

Hello,everybody!
    I'm a busybox-freshman.And I don't know how to compile busybox to be a 
cross compile version.I mean an ARM cross compile busybox.
    When I got into menuconfig,I cann't find the option 'Do you want to build 
BusyBox with a Cross Compiler.',but it's on my book!
    The cross-tools I used is arm-linux-gcc-3.3.2.While I make busybox-1.7.1 
with 'CROSS_COMPILE	?= arm-linux-', I got an error message below:

  CC      applets/applets.o

make: *** [applets] 错误 2

What should I do?
Please help.Thanks.
