Just to clarify more, if I put my code in something like:

#ifdef CONFIG_FOOBAR

my code

#endif

Then my module's Makefile should check if this parameter is defined in the ".config" file. How should I modify my Makefile to do that?

Hi,

I want to conditionally compile some code in module if CONFIG_FOOBAR is defined.

How can I add this check to my module's makefile?

-Thanks.

If I understand correctly, you want some part of your module to be compiled only

when CONFIG_FOOBAR is defined. You already mentioned the solution yourself!:

Just put that code within #ifdef CONFIG_FOOBAR and #endif

That would check the .config file and see if CONFIG_FOOBAR is defined; and only if it

is defined, that code piece gets compiled, else it will simply get stripped off.
