Installation problem with Prolog
 

Hey there
Well I am quite newbie with Linux so i would be reallly obliged to anyone who will answer my question
I have unpacked the prolog installation packet in my Desktop(therefore home/man/Desktop/)
When i first tried to install it by executing the Makefile i got a series of the same error which was Permission Denied
I tried to su and perform the same step again
Here is what i got
./Makefile: line 4: ROOT_DIR: command not found

I believe that this happens because i try to install it in a wrong directory?
Am i rigth?Any ideas?

Really thanks for your time

PS:I am using BackTrack Slackware edition if that matters

You don't execute makefiles, you run "make". It might be a good idea to tell us which Prolog implementation you're installing, or to go and look for installation documentation.
