BUSYBOX编译备忘录

BUSYBOX编译备忘录

编译busybox的组合：
busybox-1.0.0   arm-linux-gcc-2.95.3 (AT91rm9200开发板)
 
经典参考：
下载busybox
文件系统制作
 
移植基本过程：
1. 到下载busybox;
2. 解压busybox1.7.3
    tar jxvf busybox-1.7.3.tar.bz2
3. make defconfig
4. make menuconfig
　　 在[build options]中选择[Build busybox as a static binary]
    主要是C库的连接方式，安装目录等。
5. make
6. 创建rootfs目录
7. make install 
  
编译过程可能出现以下错误，解决方法如下：
  
 
可能会出现的错误：

1. 出现如下错误

　　 CC miscutils/taskset.o
　　miscutils/taskset.c:17: error: parse error before '*' token
　　miscutils/taskset.c:18: warning: function declaration isn't a prototype
　　miscutils/taskset.c: In function `__from_cpuset':
　　miscutils/taskset.c:22: error: `CPU_SETSIZE' undeclared (first use in this function)
　　miscutils/taskset.c:22: error: (Each undeclared identifier is reported only once
　　miscutils/taskset.c:22: error: for each function it appears in.)
　　miscutils/taskset.c:26: warning: implicit declaration of function `CPU_ISSET'
　　miscutils/taskset.c:26: error: `mask' undeclared (first use in this function)
　　miscutils/taskset.c: In function `taskset_main':
　　miscutils/taskset.c:47: error: `cpu_set_t' undeclared (first use in this function)
　　miscutils/taskset.c:47: error: parse error before "mask"
　　miscutils/taskset.c:68: warning: implicit declaration of function `CPU_ZERO'

　　miscutils/taskset.c:78: error: `mask' undeclared (first use in this function)
　　make[1]: *** [miscutils/taskset.o] Error 1
　　make: *** [miscutils] Error 2
　　
make menuconfig 
   找到[Miscellaneous Utilities],去掉[task set]
 

2. 如下错误：

time.c
libbb/time.c:20: error: "CLOCK_MONOTONIC" undeclared (first use in this function)
make menuconfig

  去掉Busybox Settings->Busybox Library Tuning->[]Use clock_gettie(CLOCK_MONOTONIC) syscall

3.出现如下错误：

去掉Busybox Settings->NetWork device-->[]route

4.如下错误：

usr/src/armlinux/busybox-1.0.0/libbb/loop.c:32:linux/version.h:No such file or directory
/usr/src/armlinux/busybox-1.0.0/libbb/loop.c:35 arse error
/usr/src/armlinux/busybox-1.0.0/libbb/loop.c:37 arse error

将内核源码下的include/linux目录下的versition.h文件

放到 busybox-1.0.0/include/linux下

.....
