Where did those modules get installed to?

5.make install

all steps upto 4 gave successful output but the fifth step is giving eror.that error is

Looking at how my Fedora 20 system appears to do this, I _guess_ (one of the programs called by) /sbin/installkernel is looking for these modules (and/or symbols) in /lib/modules/3.18.0-rc6+, but can't find what it needs. Does /lib/modules/3.18.0-rc6+ look comparable to what your system currently has in /lib/modules/2.6.32-431.el6.x86_64? Hope this helps, Paul Bolle
