[ePiX-users] Strange result with epix 1.2.8

[Gunnar]

Hello, 

With the epix file below, I don't get the eps file I want, and gv reports

Warning: translation table syntax error: Unknown keysym name:  apLineDel
Warning: ... found while parsing '<Key>apLineDel:     GV_Page(page+5)        '
Warning: String to TranslationTable conversion encountered errors


when loading the eps file.


My system is ubuntu 11.04 and epix 1.2.8

Any ideas on 

#include "epix.h"
using namespace ePiX;
double k=4; 
const double dx=0.1; // width of shaded region
double x = 1/sqrt(k); 
double dy=0.25;

double f(double t){
        return 1.2+Sin(t); 
}

main(){
        unitlength("1pt");
        picture(P(200,150));
        bounding_box(P(0,0),P(4.2,2.2));
        begin();

        h_axis(0);
        v_axis(0);
        label(P(xmax(),0),P(0,-1),"$u$",b);
        label(P(0,ymax()),P(-3,0),"$y$",l);
        label(P(3,f(3)),P(2,4),"$f(u)$",tr);
        label(P(1,0),P(0,-1),"$a$",b);
        label(P(3.3,0),P(0,-1),"$x$",b);
        arrow(P(0,0),P(xmax(),0));
        arrow(P(0,0),P(0,ymax()));
        gray(0.1);
        double x=0,dx=1;
        double start=0;
        x=start;
        x=start+2*dx;
        shadeplot(f,1,3.3,60);
        font_size("large");
        label(P(2,1),0,"$F(x)$");
        end();
}
