1、inotifyd出错
交叉编译busybox－1.11.1时，出现以下错误：
CC miscutils/inotifyd.o
miscutils/inotifyd.c:31:27: linux/inotify.h: No such file or directory
miscutils/inotifyd.c: In function `inotifyd_main':
miscutils/inotifyd.c:61: error: `IN_ALL_EVENTS' undeclared (first use in this function)
miscutils/inotifyd.c:61: error: (Each undeclared identifier is reported only once
miscutils/inotifyd.c:61: error: for each function it appears in.)
miscutils/inotifyd.c:129: error: dereferencing pointer to incomplete type
miscutils/inotifyd.c:139: error: dereferencing pointer to incomplete type
miscutils/inotifyd.c:140: error: dereferencing pointer to incomplete type
miscutils/inotifyd.c:140: error: dereferencing pointer to incomplete type
miscutils/inotifyd.c:143: error: invalid application of `sizeof' to incomplete type `inotify_event'
miscutils/inotifyd.c:143: error: dereferencing pointer to incomplete type
make[1]: *** [miscutils/inotifyd.o] Error 1
make: *** [miscutils] Error 2
网上说这是busybox的一个bug，解决方法：去掉对inotifyed的支持，具体步骤如下：
＃ make menuconfig
Miscellaneous Utilities --->
[ ]inotifyd
还有另一个bug是taskset，也要将它去掉，不然编译时又会出错。
Miscellaneous Utilities --->
[ ]taskset
2、启动时，BusyBox提示"/bin/sh:can't access tty;job console turn off"
解决方法：
shell --->
[ ]Job Console

3、未定义ARPHRD_INFINIBAND
错误信息如下：
networking/interface.c:818: error: 'ARPHRD_INFINIBAND' undeclared here (not in a function)
make[1]: *** [networking/interface.o] Error 1
make: *** [networking] Error 2
通过查看内核源代码目录中的“include/linux/ifarp.h”文件可知“ARPHRD_INFINIBAND”的值为“32”。然后修改“networking/interface.c”文件，在其中添加：
#define ARPHRD_INFINIBAND 32 /* InfiniBand */
