I need to build a custom module against the 4D Systems kernel (kernel4dpi-1.2-1_all). The /lib/modules/ directory only have a symbolic link to the build directory: the destination does not exist.

What would be the easiest route the build against the kernel?

I tried "sudo apt-get install kernel-headers-$(uname -r)" but I get the error "Unable to locate package kernel-headers-3.12.20".
