[metapost] Metapost btex etex problem

["Rothfuß, Ralf"]

I changed the line from %&pdflatex to %&latex

verbatimtex
%&latex
\documentclass[12pt]{article}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\begin{document}
etex
beginfig(1)
  draw (0,0)--(5cm,0) withpen pencircle scaled 1pt;
  label.rt(btex $A$ etex, (5cm, 1cm));
endfig;

end;
%% End

Compiling produces now the same error:

Again, the latex command works on the generated mpa05556.tex

The map05556.dvi looks reasonable (it contains an A with a vertical bar). If I try to invoke dvitomp it returns

c:\tmp>dvitomp mpa05556.dvi mpa05556.mpx
fatal: DVI generation failed

What is my mistake?

Best regards
Ralf

If you call pdflatex, pdftex produces pdf, not dvi, and pdf is non usable for dvitomp. It means you should call only latex, or use
\pdfoutput=0
on the next line.
