Hi, Recently, I tried to set for LuaTeX following the "Running_Mark_IV" in wiki. 1. I updated ConTeXt using "ctxtools --update". I didn't use "rsync -av ..." as in wiki for updating because I got "cannot find command texexec" error after updating ConTeXt. 2. Updated LuaTeX using "rsync -av ......../universal-darwin/" These updating processes are fine. But I got the following error when I issued "luatools --generate". LuaTools | error unable to identify cnf file LuaTools | error unable to identify cnf file LuaTools | no cnf files found (TEXMFCNF may not be set/known) LuaTools | LuaTools | runtime: 0.002 seconds I installed TL2008. The first question is that do I need to do some pre-process for the installation of LuaTeX like following? export TeXMFCNF ... export TEXMF ... ... So I run "source .luatex" where luatex is a file to setup TEXMF stuffs when I use TL2007. After that "luatools --generate" is working well. But I got another error when I try "context --make". The error message is "cannot find file context.tex". What did I do wrong in these steps? Thank you. Best regards, Dal
