LFS - kernel head building error

lebu

Error as following:
-------------------
I have no name!:/build/linux-2.4.20# make include/linux/version.h
/bin/sh: line 1: /dev/null: Permission denied
/bin/sh: line 1: /dev/null: Permission denied

make: *** [include/linux/version.h] Error 1
-------------------
When tried as root with a new shell without chroot, then turned out ok.
-------------------
[root@lebu linux-2.4.20]# cat include/linux/version.h
#define UTS_RELEASE "2.4.20"
#define LINUX_VERSION_CODE 132116
#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))
------------------
What's funny here?

BTW, why the complier always complain about "/bin/sh: line 1: /dev/null: Permission denied" ?
Everything I did was step by step according to LFS v4.1
-------------------------
I have no name!:/build/linux-2.4.20# ls -l /dev/null

你有没有/bin/sh文件呢?
ls -l /bin/sh

lebu

Sure. I have compiled some other packages already.

我不知道是哪里的问题,可能是/etc/mtab 什么的没有设置对.
这个版本的LFS 我没有装过,所以问题搞得不太清楚.
