定制根文件系统

今天准备做一个根文件系统，不过在进行静态链接时，出现了问题，如下：
[root@localhost busybox-1.6.1]# make
/_install/busybox-1.6.1/scripts/gcc-version.sh: line 1: arm-linux-gcc: command not found
/_install/busybox-1.6.1/scripts/gcc-version.sh: line 1: arm-linux-gcc: command not found
CC      applets/applets.o
/bin/sh: line 1: arm-linux-gcc: command not found
make[1]: *** [applets/applets.o] Error 127
make: *** [applets] Error 2
哪位前辈能帮我分析一下，拜谢！！！

我查了gcc-version.sh，显示的是：
#!/bin/sh
#
# gcc-version gcc-command               
#
# Prints the gcc version of `gcc-command' in a canonical 4-digit form
# such as `0295' for gcc-2.95, `0303' for gcc-3.3, etc.
#

compiler="$*"
MAJ_MIN=$(echo __GNUC__ __GNUC_MINOR__ | $compiler -E -xc - | tail -n 1)
printf '%02d%02d\n' $MAJ_MIN
什么原因？急求！

交叉工具链没安装？
