[Scons-users] Building Linux Kernel Loadable Modules

[Enrique Herrera]

env.Object('foo.o','$SRC/driver/mstpmain.c')
env.Object('bar.o','$SRC/driver/queue.c')
env.Command('foobar.o',['fo.o','bar.o'],'$LD -r $SOURCES -o $TARGET')

This is the way I got it working. I would have to create a Builder if it
gets any more complicated or more drivers in the project.

Thanks for you help.
