ln: creating symbolic link `./olsr': File exists

Plz help me

Read the LQ Rules, and don't use text-speak. And it's telling you that the symbolic link you're trying to create already exists....so, move on to the next step.

but now it shows the following error
[bash: olsr/um-olsr_ns-2.35_v1.0.patch: No such file or directory

Go back and re-read the thread you posted. Is the symbolic link valid??? Knudfl posted advice there, and following those instructions works. Also, you don't post the COMMAND you typed in to get the error you posted. We can't guess as to what you do...
