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。：
