[GAP Forum] Trouble installing XGAP

[Omid Sadeghi]

Hi,

I'm going to use XGAP package but I can't install it. 
The problem is that when I execute the make command the " configure: error: XGAP needs XWindows X11R5 or better " error occurs.

I have Ubuntu 9.04 and I think it must have X Window. 
I downloaded the latest version of X Window i.e. X11R7.5 from x.org and don't know how to install it neither because it has about 700 zipped files each of which having a separate configure and make.

How should I know whether I have X Windows in my Ubuntu 9.04 or not and if so what version do I have.

Best Regard, Omid
