Hi,all!
I'd like to compile a kernel module to Android Linux Kernel,but I have
no idea how to write the Makefile for the kernel module.
Here is my Makefile(just like pc):
obj-m= test_k.o
KERNELDIR= /home/tyz/0728/kernel/
CROSS_COMPILE= /home/tyz/0728/prebuilt/linux-x86/toolchain/arm-
eabi-4.2.1/bin/arm-eabi-
CC= $(CROSS_COMPILE)gcc
PWD= $(shell pwd)
modules:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules
modules_install:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules_install
clean:
rm -rf *.o *~ core .depend .*.cmd *.ko *.mod.c .tmp_versions
rm Module.symvers
when make modules,the Makefile do nothing but list errors as follows:
t...@debian:~/NetBeansProjects/test3GNetlink$ make modules
make -C /home/tyz/0728/kernel/ M=/home/tyz/NetBeansProjects/
test3GNetlink modules
make[1]: Entering directory `/home/tyz/0728/kernel'
ERROR: Kernel configuration is invalid.
include/linux/autoconf.h or include/config/auto.conf are
missing.
Run 'make oldconfig && make prepare' on kernel src to fix it.
WARNING: Symbol version dump /home/tyz/0728/kernel/Module.symvers
is missing; modules will have no dependencies and
modversions.
