Linux内核项目是否使用某些构建自动化软件来创建其makefile？

Question

Does the Linux Kernel Project use any build automation software such as autotools to generate their makefile ?

Do they create the makefile manually? By browsing their project Github webpage, it seems to me so, or I am missing something. But given the complexity of the project, isn't using some build automation software more convenient?

Do they use some tools to manage the complexity of their makefile?

Answer 1

The Makefiles are managed manually, but most of the complexity is confined to a few common Makefiles. See the kbuild makefile documentation for details on the Makefiles used by kbuild.

Configuration of the kernel is rather complex, as many drivers or features depend on the presence of others. The source tree includes KConfig files and several utilities for creating a valid kernel build configuration eithe interactively or from text files. See the kbuild documentation for more details.
