I have Xemacs 21.3 without gtk and Xemacs 21.5 with gtk installed, I compile the 21.5 to use gtk library on RedHat Linux 9, but only using 21.3 I have access to sintaxe hight light, html validation, and other tools. The 21.5 version is very simple I have only fundamental text. I believe that I need configure the path of 21.5 for work with this library but I don't know how I do this. If somebody know some tutorial or how-to or a can give me some way I will appreciate.
