针对嵌入式系统预编译Linux镜像和发行版在创客运动中已经很普遍,这些发行版本已经包含组件(有时候可能超过必需的),因此学生和业余爱好者们可以很容易的开始开发。Ubuntu, Debian和Arch都属于这样的发行版。
可是,当我们需要在计算机模块或者工业产品上面运行定制化或者特殊应用的Linux镜像时候,一个预编译的嵌入式Linux发行版本并不一定是最好的选择。编译一个镜像有一整套流程,在这个过程中,可以去掉任何不想要的但会导致开机时间增加,影响处理速度以及浪费内存空间的项目。很多时候我们因为系统里面有很多无用的应用和服务在运行导致系统资源浪费。举例说明,在headless应用中,桌面环境是不需要的,因此我们应该编译一个基于控制台的版本,也就是一个更快更轻量级的Linux版本。另一个使用预编译版本的弊端是授权问题,如Canonical (提供Ubuntu发行版本的公司) 就不允许在没有适当合作认证前提下随意定制和销售Ubuntu。与之相反,基于一个定制的Linux版本,我们可以完全控制所需安装的包以及使用的授权。因此,我们就可以根据项目软硬件需求拥有一个更优化的Linux镜像。
但是,如果我们想要将自己开发的Qt应用或者C应用集成到定制Linux版本中,我们该怎么做呢?是不是需要先编译应用然后复制到板子上面?还是需要先创建如”.ipk”或者”.deb”文件,然后复制到系统中去?如何将应用包含到”local.conf”文件的” IMAGE_INSTALL_append”中去?如何像其他嵌入式设备那样使应用在系统启动后自动运行?
在本文中,我们将演示如何使用OpenEmbedded/Yocto编译系统工具以自动方式来实现上面问题,我们将会快速展示基于bitbake来实现如编译,包安装,文件夹创建以及添加类似系统启动后应用自动运行服务的步骤。之后,我们将会为我们产品或者计算机模块获得一个定制化的嵌入式Linux发布版本。尽管不同开发平台或者单板之间的操作细节可能有些不同,但是原理都是一致的。
