不知有没有哪位大虾碰见过没有：
我在用arm-linux-gcc交叉编译linux-2.4.21-rmk2内核源代码时碰见以下错误,搞了好久还是没有解决,不知是什么原因........
#cd linux-2.4.21-rmk2
#make mrproper
#make xconfig
-->System Type : AT91RM9200-based
-->AT91RM9200 Implementations: y
-->Console drives:
------>VGA Text console: n
------>Frame-buffer Support: Support for frame buffer devices(EXPERIMENTAL) : y
其他为默认选项
#make dep
#make clean
#make bzImage
