我按照论坛上的方法编译成功了2.6.18的内核，但是编译2.4.18时却在make bzImage一步无法进行下去了，错误信息如下：
gcc -D__KERNEL__ -I/usr/src/linux-2.4.18/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common -pipe -mpreferred-stack-boundary=2 -march=i686 -DKBUILD_BASENAME=main -c -o init/main.o init/main.c

顶一个。
我也有相同的问题，只不过我后面的问题如上，路过的兄弟姐妹帮忙看看，

请问你的问题解决了吗？

我也是遇到的同样的问题，希望高手帮忙指点指点，谢谢啦！！
