Hello,

what is the proper way of using MetaPost with TeX text? I have two examples:


beginfig(1);
	draw unitsquare scaled(1cm);
	draw textext("$\pi$") shifted((0.5,0.5)*cm);
%	label(btex $\pi$ etex,  origin);
endfig;
end

mptopdf --metafun produces only "unknown" where the Pi symbol should
be and when I uncomment label the following problem occurs:

Output written on test-temp.dvi (2 pages, 256 bytes).
Transcript written on test-temp.log.
TeXExec | runtime: 0.16436

This is MetaPost, version 1.504 (kpathsea version 6.0.0)

mpost: Not writing to .log (openout_any = p).
! I can't write on file `.log'.
Please type another transcript file name: 

 ...
 
 
 !pdfTeX error: pdftex (file lmmi12): Font lmmi12 at 600 not found
  ==> Fatal error occurred, no output PDF file produced!
  
  MPtoPDF 1.4.1 : error while processing tex file
   
-----------------------------------------------

But, when I put source in 

\startMPpage
	draw unitsquare scaled(1cm);
	draw textext("$\pi$") shifted((0.5,0.5)*cm);
	label(btex $\pi$ etex,  origin);
\stopMPpage

and call context, the output PDF is okay. 

So what is proper way to use TeX inside mpost nowaday?

Best regards
