So, let's look at a simple Makefile for compiling a module named hello-1.c: Example 2-2. Makefile for a basic Additional details about Makefiles for kernel modules are available in linux/Documentation/kbuild/makefiles.txt. Be sure to read this Linux Kernel Makefiles This document describes the Linux kernel Makefiles. The most simple kbuild makefile contains one line: Example: obj-y += foo.o Thisare used to build the kernel based on the kbuild makefiles. === 2 Who The most simple kbuild makefile contains one line: Example: obj-y += foo.o. This tells cross platform tools, designed for linux kernel. ? include Not just linux kernel who use kbuild/kconfig Deep understanding how does makefile manage big project example: obj-$(CONFIG_GENERIC_CALIBRATE_DELAY) += calibrate.o. Apr 20, 2004 To: linux-kernel@vger.kernel.org A more advanced example - - - - - - - - - - - - This example shows a setup where a distribution M=$(PWD) $(MAKECMDGOALS) ---> End of makefile The kbuild makefile will include only a Dec 6, 2015 Kbuild's Makefiles aren't the easiest to read, but here's a high-level untangling The rule above compiles object files for both the kernel image and modules. Introduction "kbuild" is the build system used by the Linux kernel. Example 1: --> filename: Makefile ifneq ($(KERNELRELEASE),) # kbuild part of makefile Dec 26, 2012 The whole build is done recursively—a top Makefile descends into its subdirectories and executes each subdirectory's Makefile to generate the binary objects for the files in that directory. Then, these objects are used to generate the modules and the Linux kernel image. Linux Kernel Makefiles This document describes the Linux kernel Makefiles. The most simple kbuild makefile contains one line: Example: obj-y += foo.o This Oct 11, 2018 The Linux kernel config/build system, also known as Kconfig/kbuild, has been As we can see from scripts/kconfig/Makefile, there are several host programs As an example, let's look at how vmlinux is produced on x86-64:
