Hi, sorry for the silly question, but... how do you generate the desired formats after installing luatex? I've tried with luatex -ini luatex.ini dump and I get This is LuaTeX, Version beta-0.40.6-2009062619 (Web2C 2009) (INITEX) (/usr/local/texlive/2008/texmf-dist/tex/plain/config/luatex.ini (/usr/local/texlive/2008/texmf-dist/tex/plain/config/etex.ini (/usr/local/texlive/2008/texmf-dist/tex/plain/etex/etex.src ! e-TeX fatal error: this file can be processed only in extended mode; did you perhaps forget the asterisk? luatex -ini lualatex.ini This is LuaTeX, Version beta-0.40.6-2009062619 (Web2C 2009) (INITEX) (/usr/local/texlive/2008/texmf-dist/tex/latex/latexconfig/lualatex.ini (/usr/local/texlive/2008/texmf-config/tex/generic/config/pdftexconfig.tex ! Undefined control sequence. l.3 \pdfoutput =1 ? With fmtutil I had no more luck... Help? Regards, Nicola PS for Taco: I think that adding the needed commands to the INSTALL file would help a lot (also for MetaPost) people like me, who are neither beginners nor tex live gurus.
