Hi, First of all, thanks for the help about DISPLAY problem in the remote session. I tried 'ssh -X address'. Now it works well. But, I have another problem. I downloaded that C++/Motif program from my account in a school server and I run it. The result was, // Error messages shin0135@linux:~/cs2511/labs/lab6_Xdraw> make g++ -g -c ttt-main.C In file included from ttt-main.H:6, from ttt-main.C:4: typedefs.H:4: Xm/Xm.h: No such file or directory make: *** [ttt-main.o] Error 1 After this message, I thought that I don't have any motif, but SuSE installed OpenMotif automatically when it's installed. Since it might have not fully installed, I deleted and reinstalled, but still I got the same message. What's the problem....? I'll really appreciate to your help... Thanks. By the way, I attach the directory which has the openmotif. // directory shin0135@linux:/usr/X11R6/include> ls DPS X11 Xaw3d xf86Optrec.h xf86Parser.h xmms // shin0135@linux:/usr/X11R6/include/X11> ls Composite.h PM XKBlib.h Xfuncs.h Xthreads.h CompositeP.h RectObj.h XWDFile.h Xlib.h Xutil.h ConstrainP.h RectObjP.h Xalloca.h Xlibint.h ap_keysym.h Constraint.h SM Xarch.h Xlocale.h bitmaps Core.h Shell.h Xatom.h Xmd.h cursorfont.h CoreP.h ShellP.h Xauth.h Xmu extensions DECkeysym.h StringDefs.h Xaw Xos.h fonts HPkeysym.h Sunkeysym.h Xaw3d Xos_r.h keysym.h ICE Vendor.h Xcms.h Xosdefs.h keysymdef.h Intrinsic.h VendorP.h Xdefs.h Xpoll.h pixmaps IntrinsicP.h X.h Xdmcp.h Xproto.h xpm.h Object.h X10.h Xft Xprotostr.h ObjectP.h XF86keysym.h Xfuncproto.h Xresource.h _________________________________________________________________ Add photos to your e-mail with MSN 8.
