Sorry, none of this works. I think you need to see what useemp.mp
looks like.
qdf $ cat useemp.mp
%%% useemp.mp -- do not edit, generated automatically by useemp.tex
verbatimtex
\documentclass [10pt]{article}
\begin {document}
etex;
input qdftools;
beginfig(1);
LaTeX_unitlength := 28.45274pt;
w := 4*LaTeX_unitlength;
h := 4*LaTeX_unitlength;
numeric u; 10u=3in;
gridfivefive;
xyaxesfivefive;
endfig;
verbatimtex
\end{document}
etex;
%%% the end.
end.
endinput;
See, there aren't any btex ... etex commands in there. But see the
input qdftools? That file looks like this:
qdf $ cat qdftools.mp
numeric s; s=0.2;
color gridlines; gridlines:=(s,s,s);
def openbluedot(expr pos)=
fill fullcircle scaled 4pt withcolor white;
draw fullcircle scaed 4pt withcolor blue;
enddef;
def openreddot(expr pos)=
fill fullcircle scaled 4pt withcolor white;
draw fullcircle scaed 4pt withcolor red;
enddef;
def filledreddot(expr pos)=
fill fullcircle scaled 4pt withcolor red;
draw fullcircle scaed 4pt withcolor red;
enddef;
def filledbluedot(expr pos)=
fill fullcircle scaled 4pt withcolor blue;
draw fullcircle scaed 4pt withcolor blue;
enddef;
def vtick(expr pos)=
draw ((0,-3)--(0,3)) shifted pos;
enddef;
def htick(expr pos)=
draw ((-3,0)--(3,0)) shifted pos;
enddef;
def gridfivefive =
for k=-5u step 1u until 5u:
draw (-5u,k)--(5u,k) withcolor gridlines;
draw (k,-5u)--(k,5u) withcolor gridlines;
endfor;
enddef;
def xyaxesfivefive=
drawdblarrow (-5u,0)--(5u,0);
label.rt(btex $x$ etex, (5u,0));
label.bot(btex $25$ etex, (5u,0));
drawdblarrow (0,-5u)--(0,5u);
label.top(btex $y$ etex, (0,5u));
label.lft(btex $5$ etex, (0,5u));
enddef;
endinput;
And that causes the problem.
pdflatex --shell-escape useemp.tex

Now, the strange thing is that everything works if I change mpost -
tex=latex \jobname to mpost \jobname in useemp.tex.
