Hi, While trying to get some MetaPost plots converted to PDF, with the latest ConTeXt minimals installation (MkIV) on my Linux box, things happen which I don't understand, sorry! First I run the command: mtxrun --script which yields: MTXrun | TDS Runner Tool 1.26 MTXrun | MTXrun | no script name given, known scripts: MTXrun | MTXrun | babel 1.20 Babel Input To UTF Conversion MTXrun | base 1.35 ConTeXt TDS Management Tool MTXrun | cache 0.10 ConTeXt & MetaTeX Cache Management MTXrun | chars 0.10 MkII Character Table Generators MTXrun | check 0.10 Basic ConTeXt Syntax Checking MTXrun | context 0.51 ConTeXt Process Management MTXrun | convert 0.10 ConTeXT Graphic Conversion Helpers MTXrun | fonts 0.21 ConTeXt Font Database Management MTXrun | grep 0.10 Simple Grepper MTXrun | interface 0.11 ConTeXt Interface Related Goodies MTXrun | metatex 0.10 MetaTeX Process Management MTXrun | modules 1.00 ConTeXt Module Documentation Generators MTXrun | mptopdf 0.51 MetaPost to PDF Converter [more is output but NOT listed here!] When I run mtxrun --script mptopdf tobeconvertedplot.1 I get the following output: This is pdfTeX, Version 3.1415926-1.40.11 (TeX Live 2010) \write18 enabled. kpathsea: Running mktexfmt mptopdf.fmt mktexfmt: No such file or directory I can't find the format file `mptopdf.fmt'! MPtoPDF 1.4.0 : error while processing tex file By the way I've NO TeXLive installed! Why do the MTtoPDF versions (1.4 or 0.5!) not agree, and why does it not work? Do I need to install other tools to get it working? Regards, Gerard Verhaag
