RE: Shall we not use ROOT in cygwin at all ?

ROOT is built as Win32 application. (again, it has nothing to do with the brand of the compiler. One can use "gcc" to build the Win32 application too ) It is not X11 application. Win32 application needs no xterm. It has no idea what the xterm is. It uses your video hardware "directly" and "locally"  

Xterm is essentially the network tool to access the remote computer. It is not your case.  

Why do you want to use very "xterm" ?  

There is no reason to build ROOT as X11 application for Windows. One can build the X11-based ROOT too.
The outcome: it will take more memory and will be much slower. Well if this is what you want to achieve you may keep trying.

Hi Valeri

I take back what I said in the following. VC++ version have no problem in cygwin console (I just tried and it worked). The following problem shows up when running it in xterm console. The following is what I did:

cygwin:~> export DISPLAY=127.0.0.1:0.0
cygwin:~>xterm&

Then I go to the xterm and type root.exe and the probably mentioned in the following message shows up.

Thanks
