I suppose there should be some files inside /usr/src/
Today, I found that there's no audio output from my Linux PC.
Then I decide to re-install the sound driver by execute
And it show me this at the end:
checking cross compile...
checking for directory with kernel source... /usr/src/linux
checking for kernel version... The file /usr/src/linux/include/linux/version.h does not exist.
Please, install the package with full kernel sources for your distribution
or use --with-kernel=dir option to specify another directory with kernel
sources (default is /usr/src/linux).
I go to /usr/src/ and found there's nothing inside. How can it happen !?
