[NTG-context] Metapost and MPlib

Dear Sirs


I would like to include some macros from http://melusine.eu.org/syracuse/poulecl/macros in my luatex documents. Every time i try to include a new example (from papier.mp, par example) i found this old error message:; texnum.mp Unable to make mpx file.

init_numbers(btex $-$ etex,  btexetex, btex ${\times}$10etex


in the google i found a old solution for this kind of error, but for LaTeX not for mplib or LuaTeX.

Is there a fresh solution for that?


Syracuse provide to us a nice solutions for writing maths and physics with metapost.

Thanks a lot.

Jorge
