Can you post or send me your files/procedure?
Actually, I'm not sure about the procedure I followed, since I made some things by trial and error. Further, configuring a kpathsea based system is not exactly easy (the way it search files is chaotic and you never know which file tex will read, when there are several one with the same name). IIRC, what I did was: - Copy the luatex binary to /bin/win32 inside my TeXLive directory. - Copy latex.ini to the local texmf as lualatex.ini and change \input latex.ltx by \input lualatex.ltx. This file is used by fmtutil. (Usually, the directory would be texmf-local/tex/luatex.) - Copy latex.ltx to the local texmf as lualatex.ltx and comment out (or remove): \ifnum\inputlineno=\m@ne\else \lccode`\^^9d=`\i % dotted I \uccode`\^^9d=`\^^9d % dotted I \lccode`\^^9e=`\^^9e % d-bar \uccode`\^^9e=`\^^d0 % d-bar \fi which appears _twice_. This was explained by Taco himself. I commented the following lines out, too: \InputIfFileExists{hyphen.cfg} {\typeout{===========================================^^J% Local configuration file hyphen.cfg used^^J% ===========================================}% \def\@addtofilelist##1{\xdef\@filelist{\@filelist,##1}}% } {\input{hyphen.ltx}} - Find fmtutil.cnf which kpsewhich, ie: kpsewhich fmtutil.cnf (it will return the address of the file) and add the following lines to it: luatex luatex - *aleph.ini lualatex luatex - *lualatex.ini - Rebuild the ls-R databases with texhash. - Build the formats with: fmtutil --byfmt=luatex fmtutil --byfmt=lualatex I think I haven't missed any step. You might need to close the system prompt and then reopen it at some of these steps. I hope this helps. Javier
