ddd + ubuntu + gnuplot-fehler

Ich habe gerade angefangen, ddd mit Ubuntu zu verwenden. Ich kann die Grundoperationen (Schritt und Uhr) problemlos ausführen.

Wenn ich jedoch versuche, eine Grafik anzuzeigen, bleibt sie auf dem Bildschirm "Starting gnuplot" hängen.

Wenn ich das Dialogfeld storniere, wird ddd mit der folgenden Fehlermeldung beendet:

Warning: XmStringGetNextComponent: unknown type 154941792  (Annoyed? Try 'Edit->Preferences->General->Suppress X Warnings'!)

Oops! You have found a bug in DDD.

Der Code, den ich zum Testen hiermit verwende, ist

#include<iostream> using namespace std; int main() { int a[10]; for(int z=0;z<=10;z++) { a[z]=z; cout<<z; } return 0; } 

mit Ubuntu 10.04 haben Sie gnuplot von installiert

sudo apt-get install gnuplot
