[KJ] Question re make

I want to test a fix that I have made to a particular file. 

However:
	# dell:/usr/src/linux-2.6.13.2-2 # make drivers/telephony/ixj.c
	make: Nothing to be done for `drivers/telephony/ixj.c'.

and:
	# dell:/usr/src/linux-2.6.13.2-2 # make drivers/telephony
	make: Nothing to be done for `drivers/telephony'.

and
	# cc driver/telephony/ixj.cjust gives hundreds of errors.

I have done make clean (and even make mrproper) .

How can I compile just this module?

thanks,
Felix

You are "make"ing an object file, not a .c file. Makefiles' syntax is
for the target, not the source.

make drivers/telephony/ixj.o

Please read the Makefile before posting.

make M=drivers/telephony

This is just plain silly and why we have a Makefile system in the first place.

Thanks,
Nish

I had tried this all ready and forgot to mention it, but it didn't work at the 
time.

Which file should I read?

This does the trick!

I know, but  I was just trying to exaplan all the methods I had tried.
I think I must have cocked something up before but it is better now.

Thanks for your help.

Were you trying to build ixj as a module? You might have needed

make drivers/telephony/ixj.ko

Not sure, though.

The top-level Makefile gives a good overview of available
targets/syntax. The drivers/telephony/Makefile probably has some
indication of available targets specific to that directory.

Great!

Glad you got it figured out.

Thanks,

obj-m += ixj.o
all:
        make -C /<blah>/<blah>/kernel-2.6.11/linux M=$(PWD)
modules
 
Try adding this to your standalone make file.  I hope this answers
your question.
