Good day! I am a MKII ConTeXt user who is interested in trying out MKIV. Tried installing MKIV on my MacBook (running Mac OS X Leopard) as instructed in Contextgarden but I cannot run it to compile using either TeXShop or the Terminal. The following are the steps I have taken to install MKIV: 1. tlmgr update --all 2. rsync -av rsync://contextgarden.net/minimals/current/context/current/ /usr/local/texlive/2008/texmf-dist/ 3. rsync -av rsync://contextgarden.net/minimals/current/bin/luatex/osx-universal/bin/luatex /usr/local/texlive/2008/bin/universal-darwin/ 4. luatools --generate 5. context --make 6. mktexlsr 7. texexec --make --all 8. texexec --make --xtx --all 9. context --make cont-en At this point I encounter an error saying, "SORRY CONTEXT NOW NEEDS ETEX." Below is the Terminal output of the above command: MtxRun | running command: luatools --make --compile cont-en LuaTools | creating initialization file: cont-en LuaTools | using library path: /usr/local/texlive/2008/texmf-dist/tex/context/base LuaTools | using lua libraries: l-string.lua l-lpeg.lua l-table.lua l-boolean.lua l-number.lua l-set.lua l-unicode.lua l-md5.lua l-os.lua l-io.lua l-file.lua l-url.lua l-dir.lua l-utils.lua l-dimen.lua luat-lib.lua luat-inp.lua luat-env.lua luat-tmp.lua luat-zip.lua luat-tex.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-string.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-lpeg.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-table.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-boolean.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-number.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-set.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-unicode.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-md5.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-os.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-io.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-file.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-url.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-dir.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-utils.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/l-dimen.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/luat-lib.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/luat-inp.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/luat-env.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/luat-tmp.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/luat-zip.lua LuaTools | merging library /usr/local/texlive/2008/texmf-dist/tex/context/base/luat-tex.lua LuaTools | saving merge from cont-en.lua LuaTools | using compiled initialization file: cont-en.luc LuaTools | using lua initialization file: cont-en.luc LuaTools | running command: luatex --ini --lua="cont-en.luc" "/usr/local/texlive/2008/texmf-dist/tex/context/base/cont-en.tex" \\dump (/usr/local/texlive/2008/texmf-dist/tex/context/base/cont-en.tex (/usr/local/texlive/2008/texmf-dist/tex/context/base/context.tex SORRY CONTEXT NOW NEEDS ETEX ) ) mkiv lua stats : used config path - /usr/local/texlive/2008/texmf.cnf;/usr/local/texlive/2008/texmf/web2c/texmf.cnf mkiv lua stats : used cache path - /Users/jcmmd317 mkiv lua stats : input load time - 0.115 seconds mkiv lua stats : current memory usage - 6 MB (ctx: 6 MB) mkiv lua stats : node memory usage - 1 dir mkiv lua stats : control sequences - 332 of 115536 mkiv lua stats : callbacks - direct: 7, indirect: 41, total: 48 LuaTools | LuaTools | runtime: 0.650 seconds MtxRun | total runtime: 0.753 I ignored this error and proceeded to making the Context-MarkIV engine file for TeXShop. However, all I get is this error : MtxRun | unknown script 'context.lua' or 'mtx-context.lua' Using 'locate' in Terminal, I get the following output: /usr/local/texlive/2008/texmf-dist/scripts/context/lua/mtx-context.lua Does anybody have any idea as to why I cannot run ConTeXt-MKIV? Any help would be greatly appreciated. Thanks! joel mendoza
