From: hacklu on 9 Aug 2010 04:10 I have a driver project programmed under the 2.4 kernel. but now ,I want to transplant it to 2.6. the driver has some directions; like 1/1.c 2/2.c 3/3_1.c 3_2.c in this case ,how can I imtate the template Makefile of 2.6's driver I only kown this: ------------------------------------------ ifneq ($(KERNELRELEASE),) # call from kernel build system scull-objs := demo1.o demo2.o obj-m := demo.o else CROSS_COMPILE ?=powerpc KERNELLIBDIR=/lib KERNELDIR ?= /linux-2.6.25_minifo PWD := $(shell pwd) all: $(MAKE) CROSS_COMPILE=$(CROSS_COMPILE) ARCH=powerpc -C $(KERNELDIR) M=$(PWD) modules clean: rm -rf *.o *~ core .depend .*.cmd *.ko *.mod.c .tmp_versions endif depend .depend dep: $(CC) $(CFLAGS) -M *.c > .depend ifeq (.depend,$(wildcard .depend)) include .depend endif ----------------------------------------- thanks so much -------------- hacklu 2010-08-09 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

However there are many articles and guides on the 'net that can: a google search for "linux kernel porting driver 2.4 2.6" will suffice; just look at the first few hits. If you need more help on Kconfig this may also help you: http://www.kernel.org/doc/Documentation/kbuild/kconfig-language.txt ..
