Tried make. Got
[root@localhost ndiswrapper-1.52]# make
make -C driver
make: Entering directory `/home/arun/ndiswrapper-1.52/driver'
Makefile:24: *** Kernel tree not found - please set KBUILD to configured kernel. Stop.
make: Leaving directory `/home/arun/ndiswrapper-1.52/driver'
make: *** [all] Error 2
Problem was I dint have the source, downloading source. But what is the kernel number ?
I knew I had a source downloaded somewhere...
find | grep '2\.6'
