Re: Can't build loadable module for 2.6.kernel

Hi Sam,

Thanks to your help and the kbuild documentation you referred me to I was able to build the module.

Thanks again,

Hi all,

I hope this is the right forum for this question.


Yes.



The makefile has the following rule to build apicnt.o:
apicnt.o: apicnt.o.shipped
cp apicnt.o.shipped apicnt.o



This is wrong. kbuild has knowledge how to copy a file named:
apicnt.o_shippd to apicnt.o
So you renamed the supplied .o fiel to apicnt.o_shipped and delte your
own rule.




#
# Makefile for the phone_mrvl driver loadable module
#
TARGET = phone_mrvl.o

obj-$(CONFIG_PHONE_MARVELL) = phone_mrvl.o

ifeq ($(CONFIG_PHONE_LEGERITY),y)
phone_mrvl-objs = mrvphone.o slic.o legerity.o vp_hal.o sys_service.o apicnt.o apiinit.o apiquery.o vp_api.o vp_api_common.o mvutils.o
endif


Please do:
phone_mrvl-$(CONFIG_PHONE_LEGERITY) := mrvphone.o slic.o legerity.o phone_mrvl-$(CONFIG_PHONE_LEGERITY) += vp_hal.o sys_service.o apicnt.o phone_mrvl-$(CONFIG_PHONE_LEGERITY) += apiinit.o apiquery.o vp_api.o
phone_mrvl-$(CONFIG_PHONE_LEGERITY) += vp_api_common.o mvutils.o



ifeq ($(CONFIG_PHONE_PROSLIC),y)
phone_mrvl-objs = mrvphone.o proslic.o
endif


phone_mrvl-$(CONFIG_PHONE_PROSLIC) += mrvphone.o proslic.o



CFLAGS += -D__linux__
EXTRA_CFLAGS += -Idrivers/telephony/mrvphone
EXTRA_CFLAGS += -DNDEBUG -Dlinux -D__linux__ -Dunix -DEMBED -DLINUX -DHOST_LE

ifeq ($(CONFIG_PHONE_LEGERITY),y)
EXTRA_CFLAGS += -D__LEGERITY__
endif
ifeq ($(CONFIG_PHONE_PROSLIC),y)
EXTRA_CFLAGS += -D__PROSLIC__
endif


Here you could do:
extra-cflags-$(CONFIG_PHONE_LEGERITY) += -D__LEGERITY__
extra-cflags-$(CONFIG_PHONE_PROSLIC)  += -D__PROSLIC__
EXTRA_CFLAGS += $(extra-cflags-y)

Please delete the rest - it is not needed.


all: $(TARGET)

$(TARGET): $(OBJS)
	$(LD) -r $(OBJS) -o $(TARGET)

clean:
	-rm -f $(TARGET) *.elf *.gdb *.o

apicnt.o: apicnt.o.shipped
cp apicnt.o.shipped apicnt.o



When you build your module use:
make -C $PATH_TO_COMPILED_KERNEL M=`pwd`

See also Documentation/kbuild/modules.txt for further reference.
