They should all be there automagically. A few things to try out... What machine is this being build on?
Your Makefile contains this: > ifeq ($(KVER),) > ifeq ($(KDIR),) > KVER = $(shell uname -r) > KDIR := /lib/modules/$(KVER)/build > endif > else > KDIR := /lib/modules/$(KVER)/build > endif >
But does /lib/modules/... contain a sparc kernel?
You could try to build your module using: V=1
And reply with the output. This should give a clue about what flags are picked up from where.
Most of your Makefile looks fine - I guess we need to find the bug in the build environmnet and not in the Makefile.
