Linux: modpost does not build anything

Question

I am having problems getting any kernel modules to build on my machine. Whenever I build a module, modpost always says there are zero modules:

MODPOST 0 modu         


        

Answer 1

I was able to solve this problem by putting the

obj-m += .o

In a separate file named Kbuild. See Linux/documentation/kbuild/modules.txt for a hint as to why this might work
