Building kernel module twice

[Nithin]

I have a kernel module that needs to be built twice. once without -DFLAG and once with -DFLAG. i want to create two modules module_flag.ko and module_noflag.ko

How can I modify the makefile to build two modules one with flag and one without?

Thanks,
N.

Build a module with the flag.
Find the *.ko file(s)
copy those to a safe place.
make clean
then edit the makefile manually to get rid of the flag
build it again.

That's the approach I would go.

drag, yes that is what we are doing right now. we're currently overwriting the makefile with a new one that does not have the flag.

i was hoping for something where i could specify it in the makefile itself. with just one makefile. through some makefile trick.

I'm sure you can just add a few lines at the end of the makefile that tell it to do so.
