Hi there, i'm having problems with metapost and positional graphics in mkIV. Here is a small test file that compiles OK with texexec but fails to compile with context: % the beginning \defineoverlay[frames][\positionoverlay{frames}] \setupbackgrounds[page][background=frames] \startMPpositiongraphic{frame} initialize_box(\MPpos{\MPvar{self}}); draw llxy--lrxy--urxy--ulxy--cycle; \stopMPpositiongraphic \startpositionoverlay{frames} \setMPpositiongraphic{one}{frame} \setMPpositiongraphic{two}{frame} \stoppositionoverlay \starttext This \hpos{one}{word} should be \hpos{two}{framed}. \stoptext % the end My system is a Debian Testing, but I don't believe that it is related to the distribution, as this example also fails in the context online compiler @ http://live.contextgarden.net/ The problem seems located around the initialize_box macro. Any help will be much appreciated. AG. Here is the entire output when compiling: $ context essai.tex mtx-context | run 1: luatex --fmt="/var/lib/texmf/luatex-cache/context/f919750633122078d706dd10f1cfd39b/formats/cont-en" --lua="/var/lib/texmf/luatex-cache/context/f919750633122078d706dd10f1cfd39b/formats/cont-en.lui" --backend="pdf" "./essai" \stoptext This is LuaTeX, Version beta-0.70.2-2012070300 (TeX Live 2012/Debian) \write18 enabled.
