I am trying to install a program on a NSLU2 running Debian. It asks me:

Code:

Linux kernel (2.6.18-5-ixp4xx) source directory [/usr/src/linux]:

The problem is that I do not have a linux folder in /usr/src/.

This is what an ls or my /usr/src directory shows:

Code:

linux-headers-2.6.18-5 linux-headers-2.6.18-5-ixp4xx linux-kbuild-2.6.18

I tried doing an apt-get install linux-image-`uname -r` a but that returns:

Code:

linux-image-2.6.18-5-ixp4xx is already the newest version.

where do I find the linux kernel source directory or how do I get it if I do not already have it?

Thank you!

aptitude install linux-source-2.6.18

Then you might have to manually unpack it in the source directory and/or create a symlink (man ln).

where do I get the file to unpack or where do I sym link from?

It should install to the /usr/src directory automatically. I just don't remember if it comes in as a tgz file or whether it all unpacks for you.

It turns out I had to do apt-get install linux-source-2.6.18
