Upshot and Nupshot

The upshot and nupshot programs require specific versions of the tcl and tk languages. This section describes only problems that may occur once these tools have been successfully built.

General

1. Q: When I try to run upshot or nupshot, I get


No display name and no $DISPLAY environment variables 

A: Your problem is with your X environment. Upshot is an X program. If your workstation name is "foobar.kscg.gov.tw", then before running any X program, you need to do


setenv DISPLAY foobar.kscg.gov.tw:0 

If you are running on some other system and displaying on foobar, you might need to do


xhost +othermachine 

on foobar, or even


xhost + 

which gives all other machines permission to write on foobar's display.

If you do not have an X display (you are logged in from a Windows machine without an X capability) then you cannot use upshot.


2. Q: When trying to run upshot, I get


upshot: Command not found. 

A: First, check that upshot is in your path. You can use the command


which upshot 

to do this.

If it is in your path, the problem may be that the name of the wish interpreter is too long for your Unix system. Look at the first line of the upshot file. It should be something like


#! /usr/local/bin/wish -f  

If it is something like


#! /usr/local/tcl7.4-tk4.2/bin/wish -f  

this may be too long of a name (some Unix systems restrict this first line to a mere 32 characters). To fix this, you'll need to put a link to wish somewhere where the name will be short enough. Alternately, you can start upshot with


/usr/local/tcl7.4-tk4.2/bin/wish -f /usr/local/mpi/bin/upshot
