Re: Problem in compiling a kernel module

Dear Kumaran,

Try to compile with the below makefile

"
obj-m += hello-1.o

all:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

clean:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean"


Regards
Sharief

Edit the Makefile and add the following echo's

`default:
   echo $(MAKE)
   echo $(KERNELDIR)
   echo $(PWD)
   $(MAKE) -C $(KERNELDIR) M=$(PWD)

You can try echoing the values of the variables. The $(MAKE) is the
make command used.

Thanks sir, It worked. But still I couldn't understand what is the wrong in the makefile given in TLDP.org, also the if statements as said in the previous mail.
One more thing can I install the new kernel in a virtual machine like virtual box? if so how can I do it? coz I can't access Internet from that kernel. Suggesting some measures will be helpful.
