[metapost] Unable to make mpx file. Btex and etex issue

[ozhan fenerci]

Dear List,

I am trying to learn metapost. I found a book which uses metapost extensively. I wanted to compile the a few example from it but I failed.

mpost works until it hits the line " label(btex{\small $c$} etex,(-15w,.5c));". Mpost gives the error like :

$mpost ch1.mp


This is MetaPost, version 1.208 (kpathsea version 5.0.0)

I don't know what have gone wrong but sometihing about "btex and etex" issue. I am using TexLive 2009/Debian.

Ozhan
