symbolic links
 

Ok so I have my 2.6 kernel installed and booting just fine with grub. However, I can't seem to make the symbolic link between by 2.6 kernel directory (/usr/src/linux-2.6.0) and the /usr/src/linux directory. I was trying to emerge a package in gentoo and it said the kernel version was not determined. I was trying to make the link with ln -s but it said linux/linux-2.6.0 : file exists. Is there something else I am doing wrong? I still have my 2.4 kernel installed as well, because I am still testing things with 2.6 before I commit.

did you do it the wrong way? :) I mean, the command goes like this:

ln -s source_directory symlink_name

where source_directory is the dir you want to be linked (/usr/src/linux-2.6.0) and symlink_name is the name of the symlink you want to create (/usr/src/linux). the symlink_name component must not already be there, because if it does, it would be overwritten and that's not done. so if you did

ln -s /usr/src/linux /usr/src/linux-2.6.0

then you got the error because a dir called /usr/src/linux-2.6.0 already exists (but on the other hand, there is no - or at least should not be - a thing called /usr/src/linux). so, to get this correct:

1) if you already have a symlink called /usr/src/linux, remove it:

file /usr/src/linux
(now this should print a line like this -> XXX: symbolink link to 'YYY' and if it does, then it is a symlink and can safely be erased. if you get an error which tells you that there is no such thing as /usr/src/linux, just move on, over the next step)
rm /usr/src/linux

2) create the symlink to the 2.6.0 directory:

ln -s /usr/src/linux-2.6.0 /usr/src/linux

and you should be fine.

Ok, you were right that worked just fine. I didn't know that the /usr/src/linux shouldn't have already been there ... I actually created that directory and tried to link it, but what you said makes sense. As always thanks for the help!

heh, no problem :)

Ok. Now how is it done in the GUI, KDE or Gnome. Please and thank you.
