I have been trying to install some Linux software, particularly KPopup, but I have had a similar problem with LinPopup and KxICQ (although I have found RPMs for those, so I have been able to install them).
The problem is, when I am installing by compiling, instead of from RPMs, after I type "make", the error "missing separator" is eventually encountered. Sometimes (as with KPopup), it is encountered right from the start: other times, it compiles a long way before getting to the errors. It does get there eventually.
I have double checked to see whether I have installed GCC, and I have. Still the same problem. Any ideas?
