How to add my modules into android kernel from outside of kernel src tree?

[chungae9ri]

Hi all
I put my module src files of helloworld into vendor/xxx/modules and I
want to add my driver modules into android but I can't build it.
this is my Makefile, it's simple

obj-m += Hello.o
modules:
<tab> $(MAKE) -C $(KERNELDIR) M=$(PWD) ARCH=$(ARCH) CROSS_COMPILE=$
(CROSS_COMPILE) modules

when I "make modules" the following error occurs

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.

CC [M] /media/slave2/work/xxx/LINUX/android/vendor/xxx/modules/
Hello.o
cc1: error: include/linux/autoconf.h: No such file or directory

How can I fix this?

The following will solve the problem:

obj-m += Hello.o
all:

    $(MAKE) -C $(KERNELDIR) M=$(PWD)  modules
install:

Sorry for my previous wrong and incompleter posts.....

The following will solve the problem:

obj-m += Hello.o
all:

  @ $(MAKE) -C $(KERNELDIR) M=$(PWD)  modules
install:

   @$(MAKE) -C $(KERNELDIR) M=$(PWD)  modules_install

 clean:

    rm -f *.o *.ko *.mod.c *.mod.c *.mod.o .*.cmd *~ modules.order Module.symvers

 

 

The above is the Makefile and in your module source directory give the following command:

$ make KERNELDIR=/path/linux/kernel/sources/

make modules_prepare steps hasn't been done... and hence those errors...
But I still don't understand how you would be able to build modules
from android.mk file.
