Hi all, I have the one .c source file that I want to create multiple kernel modules out of it by setting macros using the makefile. The idea is that if -DMODULE1 is set, I'll build module1.ko and if -DMODULE2 is set, I'll build module 2. Does anyone know how to do this? I created the following makefile: ... module1: override obj-m := module1.o module1: EXTRA_CFLAGS += -DMODULE1 module1: $(MAKE) -C $(KDIR) M=$(PWD) modules module2: override obj-m := module2.o module2: EXTRA_CFLAGS += -DMODULE2 module2: $(MAKE) -C $(KDIR) M=$(PWD) modules ... But it isn't working as I expected. Anyone with kernel build system experience knows the answer for that? Thanks, -- Henrique Rodrigues
