into a shell (Konsole, Xterm etc.) produces an error, then you'll have to install it using Yast. This is almost certainly the case, as Suse Personal doesn't come with much in the way of compilation tools, from memory.
You will also need to install gcc
and the standard libraries, at the very least. Searching for "gcc" in Yast should give you most of these, as long as you have the 'check dependencies' box ticked.
