Dear Folks, I am a LaTeX user trying out ConTeXt for the first time. I am running TeXLive 2010 (full scheme) on a x86_64-linux platform. I have visited http://wiki.contextgarden.net/Running_Mark_IV and put the instructions there into an executable file: --- #! /bin/bash # # Manual update for ConTeXt in TeXLive 2010 as suggested at # # http://wiki.contextgarden.net/Running_Mark_IV # # Update ConTeXt rsync -av rsync://contextgarden.net/minimals/current/context/current/ /usr/local/texlive/2010/texmf-dist/ # Update LuaTeX rsync -av rsync://contextgarden.net/minimals/current/bin/luatex/linux-64/bin/luatex /usr/local/texlive/2010/bin/x86_64-linux/ # Run equivalent mktexlsr luatools --generate context --make context --make cont-en --- The last output lines after running this file are: --- LuaTools | runtime: 1.610 seconds .../2010/texmf-dist/scripts/context/lua/mtx-context.lua:985: attempt to call upvalue 'make_mkiv_format' (a nil value) .../2010/texmf-dist/scripts/context/lua/mtx-context.lua:985: attempt to call upvalue 'make_mkiv_format' (a nil value) --- When I compiled a trivial file called first.tex using texexec first I got in the output, inter alia, --- ConTeXt ver: 2010.07.30 11:35 MKII fmt: 2010.10.5 int: english/english --- Why am I not seeing Mk-IV yet? I have used LuaLaTeX with fontspec quite successfully and would like to try ConTeXt with LuaTeX support in Mk-IV to compare ease of customization and use. I am happy to furnish more information if necessary. Sorry if my query sounds elementary, but I am new to ConTeXt. Thanks in advance. Chandra
