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 ...

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 ...

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 ...

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 ...
