2.2 菜单配置
BusyBoxy各目录都有一个Config.in文件,里面保存了BusyBox的配置信息,我们可以手动修改Config.in以达到配置的目的,但是这样子比较麻烦。所幸的是,BusyBox提供了一个菜单式的配置工具,执行如下命令即可调出此工具:
make menuconfig
配置界面如下图:
图1 BusyBox菜单配置主界面
第一次执行make menucofig时,可能会出错:
图2 启动BusyBox菜单配置时遇到的问题
根据上图红色圈住部分的提示可知,当前系统缺乏curses.h头文件,执行下面命令安装curves即可:
sudo apt-get install libncurses-dev
2.2.1 编译设置
Busybox Settings --->
Build Options --->
图3 编译设置
(1)静态编译
通过空格键使能Build BusyBox as a static binary(no shared libs)(对应的方括号处显示星号*即为使能状态)。
(2)交叉工具链前缀
设置Cross Compiler prefix如下所示(具体路径和交叉工具链前缀根据实际情况修改):
图4 交叉工具链前缀
若将交叉编译工具链的路径(home/liyihaiMini2440/Toolschain/4.4.3/bin)添加到Ubuntu的PATH环境变量中,则在上图中只要指定arm-linux-即可,若当前系统中没有相应的交叉工具链或者输入有误,在保存退出时会提示错误:
图5 交叉工具链输入错误
2.2.2 安装设置
Busybox Settings --->
Installation Options("make install" behavior) --->
图6 安装设置
由上图可见,默认情况下值执行make install时BusyBox会被安装在其顶层目录的_install目录中。安装目录可以根据需要进行修改:通过向下方向键选中上图的(./_install)BusyBox installatiion prefix选项,然后输入安装路径即可:
图7 BusyBox安装路径
2.2.3 基本配置
Busybox Settings --->
General Configuration --->
[*]Don‘t use /usr
这个必需选中,否则在安装的时候将会将BusyBox安装在Ubuntu的/usr目录中,从而损坏了宿主机的根文件系统!
2.2.4 退出保存
退出时记得确认保存,否则上述配置无效。
图8 退出保存
3 编译
make
若没有在图4中设置交叉编译工具链前缀,则需要通过下述命令比编译和安装:
make ARCH=arm CROSS_COMPILE=arm-linux- CONFIG_PREFIX=/home/liyihai/Mini2440/rootfs all install
3.1 编译错误
执行make命令编译时(使用友善之臂的交叉工具链),出现错误如下:
图9 友善之臂交叉编译器编译错误
改用创龙的交叉工具链,出现错误如下:
图10 创龙交叉编译器编译错误
上述两幅图的错误是不一样的,因此可知说出现的错误与具体的编译器有关!
3.2 搜索选项
配置选项特别多,且在不同的BusyBox版本中,同一个选项可能会被安排到不同的菜单中,因此人工查阅特定的选项比较麻烦,幸好有搜索选项的工具,在任意菜单界面中输入斜杠“/”即可进入搜索框:
图11 搜索框
在上图中输入util关键字,搜索结果如下:
图12 搜索结果
上图显示了包含关键字util的菜单位置,这个功能有助于定位引起编译错误的选项。
3.3 取消引起错误的选项
再次执行make menuconfig,取消引起编译的选项,然后重新编译即可解决上述编译错误。
对于图9的错误,取消umount选项即可:
Linux System Utilities --->
[ ] umount
对于图10的错误,取消sync选项即可:
Coreutils --->
[ ] sync
4 安装
执行如下命令可将BusyBox安装到指定目录(如果用户没有设置,则默认安装目录为_install):
make install
上述命令会在安装目录中生成bin、sbin两个目录以及linuxrc一个链接文件。:
图13 安装结果
