安装skyeye时cc command not found

wyn

编译安装skyeye时执行./configure --target=arm-elf --prefix=/usr/local后出现：
configuring for a i686-pc-linux-gnu host
created "Makefile" in opt/skyeye-cdrom/SkyEye/skyeye/skyeye
./configure: line 8 : cc command not found
*** the command 'cc -o conftest -g conftest.c' failed
***you must set the environment variable CC to
a working compiler.
请问是什么问题？
