Petalinux可以帮助工程师简化内核模块的创建工作。在petalinux工程目录下，使用命令“ petalinux-create -t modules --name --enable”，能创建Linux内核模块，包括c源代码文件，Makefile，Yocto的bb文件。相关文件放在目录“ project-spec / meta-user / recipes-modules”中，目录结构如下。

我们在编译Linux内核时，往往在Linux内核的顶层目录会执行一些命令，这里我以RK3288举例，比如：make firefly-rk3288-linux_defconfig、make menuconfig、make firefly-rk3288.img、make zImage等等。先不管这具体的含义，首先提出几个疑问 （1）Linux内核如此庞大（几万个文件），目录 ...

Makefile可以根据指定的依赖规则和文件是否有修改来执行命令。常用来编译软件源代码，只需要重新编译修改过的文件，使得编译速度大大加快。 Makefile的基本格式 目标：依赖 命令 目标是要生成的结果，依赖是生成结果需要的源文件和上一步骤的结果，命令是 ...

One amazing thing about Linux is that the same code base is used for a different range of computing systems, from supercomputers to very tiny embedded devices. If you stop for a second and think about ...

GNU makefiles let your small business put out source code that can adapt its compilation to a specific client's machine, and preemptively detect problems or unmet software dependencies. Checking to ...

In a compiled language, the makefile is arguably the most important part of any programming project. To compile your project, you first have to compile each source file into an object file, which in ...
