1)下载,解压busybox1.6.1(地址：www.busybox.net/downloads )
2)make defconfig
3)make menuconfig
在[build options]中选择[Build busybox as a static binary]
4)make
出现如下错误
CC applets/applets.o
applets/applets.c:20:2: warning: #warning Static linking against glibc produces buggy executables
applets/applets.c:21:2: warning: #warning (glibc does not cope well with ld --gc-sections).

make[1]: *** [applets/applets.o] Error 1
make: *** [applets] Error 2
看来是做为static时不建议用glibc,图省事,不考虑生成文件会大的问题,不打算换uclibc,将applts/applets.c的第19到27行注消
5)make
出现如下错误

make menuconfig 找到[Miscellaneous Utilities],去掉[task set]
5)make
6)make install
搞定,生成的busybox是1.1M,如果不编译成static的话是500多K,但要带gclib用运行.生成的bin和sbin里的程序,还有linuxrc都是指向bin/busybox的符号链接. |
