Makefile problem and modules

Makefile problem and modules

[Emmanuel Varagnat]

I wrote a module for IPv6 but there is a case when it is
compiled.
(For the moment my code can only work as a module...)
When IPv6 is compiled as a module, my module is well compiled.
But if IPv6 is directly in the kernel, my module is not take
into account (I've got no object file).

Here is the only line I added to the Makefile (near the end):

obj-$(CONFIG_IPV6_MYSTUFF)  += mystuff.o

Thanks in advance.

Changes in the Config.in file?

Yes just a tristate option.
And after doing config/menuconfig/xconfig, the .config file
contain a line with CONFIG_IPV6_MYSTUFF=m

I can't figure out where it comes from.
I must say I also read Documentation/kbuild/makefiles.txt.

Thanks.

In which directory? net/ipv6/ ?

Maybe you need to add

subdir-m += ipv6

in net/Makefile then.
net/ipv6 is not processed during module compilation when CONFIG_IPV6=y
(except net/ipv6/netfilter).
