I am using Ubuntu 9.0.4 and currently building out of the source tree,
infact I am using the existing Ubuntu hearder files to build my sample
driver. Do I really need to get the source tree for building modules?
Secondly, I am not sure
where to run make prepare_modules can you please specify the exact location.
1. Kernel Module build location: my local directory
(/home/vipul/linux/ucsc/ldd/)
2. uname -r: 2.6.28-11-generic
3. r...@ubuntu:/usr/src# ls
linux-headers-2.6.28-11 linux-headers-2.6.28-11-generic nvidia-180.44
Regards,
Vipul.
