I have a device (a camera from Finger Lakes Instrumentation), and the vendor sent me source code for a kernel module. I know nothing about compiling kernel modules. Here's the makefile:

` obj-m := fliusb.o

KDIR ?= /lib/modules/$(shell uname -r)/build PWD := $(shell pwd)

EXTRA_CFLAGS += -O2 -Wall

EXTRA_CFLAGS += -DDEBUG # enable debug messages

EXTRA_CFLAGS += -DASYNCWRITE # enable asynchronous writes

EXTRA_CFLAGS += -DSGREAD # enable scatter-gather reads

all: module cleanup

module: $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

cleanup: rm -f .o ..cmd *.mod.c; rm -rf .tmp_versions

clean: cleanup rm -f *.ko test `

I had to invoke this with make -C /usr/src/linux to get it to even start. It compiles a few things, but fails with the following. Any ideas?

make: Entering directory '/usr/src/linux-headers-4.4.54-ti-r93' CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h make[1]: No rule to make target 'arch/arm/tools/gen-mach-types', needed by 'include/generated/mach-types.h'. Stop. arch/arm/Makefile:313: recipe for target 'archprepare' failed make: [archprepare] Error 2
