Some of the compiler operations that you are about to invoke with make, require that the linux kernel stuff be found in the /usr/src/linux directory. Your new Mandrake system may or may not have such a directory. You can find out using the explorer shown above or you can use the console. If you use the explorer, you may have some difficulty removing a link by deleting it. I found some kind of conflict that developed so I'll only show the console procedures below.
The konsole window allows you to repeat commands by pressing the up arrow until you get to the command that you wish to enter again. This feature makes it so that you do not have to type all commands. You can just find the one you want and repeat it by pressing enter or return. (note that in the directory command ls -l that l is lowercase L)
[root@localhost /root]# cd /usr/src
[root@localhost src]# ls
-l

I see from the fifth line that - linux ->linux-2.2.14. So the linux file in this directory is a link. Since it is only a link I can delete it and then check to make sure it is gone.
[root@localhost src]# rm
linux
rm: remove `linux'? y
[root@localhost src]# ls
-l

Now if it is a real directory with a bunch of sub directories, I'd need to move it to some other location. I'd do that by first seeing that it was a directory rather than a link to a directory.
[root@localhost src]# ls
-l

drwxr-xr-x 7 root root 4096

drwxr-xr-x 3 root root 4096

I see from the light red line that linux is a common directory - its line begins with d rather than l and it just has a / after its name. I need to move this linux directory out of the way before I compile a new kernel. I'll called it linuxold. The mv command with the linux name and linuxold as the new name, does the deed for me.
[root@localhost src]# mv
linux linuxold
[root@localhost src]# ls
-l
total 16
drwxr-xr-x 7 root root 4096 May 16 06:47 RPM/
drwxr-xr-x 20 root root 4096 May 16 10:42 linux-2.2.14/
drwxr-xr-x 3 root root 4096 Jun 4 17:36 linuxold/
drwxr-xr-x 4 root root 4096 Nov 25 1999 rtlinux-2.2/
Now you need to make a new link in place of the old /usr/src/linux
[root@localhost src]# ln
-s rtlinux-2.2/linux linux
[root@localhost src]# ls
-l
total 16
drwxr-xr-x 7 root root 4096
May 16 06:47 RPM/
lrwxrwxrwx 1 root root 17
Jun 4 17:49 linux -> rtlinux-2.2/linux/
drwxr-xr-x 20 root root 4096
May 16 10:42 linux-2.2.14/
drwxr-xr-x 3 root root 4096
Jun 4 17:36 linuxold/
drwxr-xr-x 4 root root 4096

Make certain that the link goes from /usr/src/linux to the realtime/linux. Not the other way round. With this done we are ready to get down to work.
