I am far from being any kind of compiling guru. In attempting to compile plex86 on my Mandrake 8.0 machine, I get the following errors: x.cc:21:22: X11/Xlib.h: No such file or directory x.cc:22:23: X11/Xutil.h: No such file or directory x.cc:23:21: X11/Xos.h: No such file or directory x.cc:24:23: X11/Xatom.h: No such file or directory x.cc:25:24: X11/keysym.h: No such file or directory make[4]: *** [x.o] Error 1 make[4]: Leaving directory `/home/hoyt/Downloads/plex86/plex86-kevin/user/plugins/bochs/gui' make[3]: *** [gui/libgui.a] Error 2 make[3]: Leaving directory `/home/hoyt/Downloads/plex86/plex86-kevin/user/plugins/bochs' make[2]: *** [all] Error 2 make[2]: Leaving directory `/home/hoyt/Downloads/plex86/plex86-kevin/user/plugins' make[1]: *** [ALL] Error 2 make[1]: Leaving directory `/home/hoyt/Downloads/plex86/plex86-kevin/user' make: *** [all] Error 2 Obviously, I need some headers for X.. What file contains these? Thanks,
