Is it possible to build a kernel module from several source files which one of them has the same name as the module?
For example: I want to build "mymodule.ko" with the following source files:
mymodule.c
mymodule_func.c
This makefile doesn't work:
#Makefile obj-m += mymodule.o mymodule-objs := mymodule.o mymodule_func.o thanks

In computing, a loadable kernel module (LKM) is an object file that contains code to extend the running kernel, or so-called base kernel, of an operating system. LKMs are typically used to add support for new hardware (as device drivers) and/or filesystems, or for adding system calls.
Look at modprobe(8) which is the linux command to install a module into the kernel.
depmod(Dependency Modules) command is used to generate a list of dependency description of kernel modules and its associated map files. This analyzes the kernel modules in the directory /lib/modules/kernel-release and creates a “Makefile”-like dependency file named modules.
I found a solution, I placed my source file in a sub folder:
Makefile
src/mymodule.c
src/mymodule_func.c
#Makefile obj-m += mymodule.o mymodule-objs := ./src/mymodule.o ./src/mymodule_func.o all: make -C $(KERNEL_PATH) M=$(PWD) modules clean: make -C $(KERNEL_PATH) M=$(PWD) clean If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
