Hi, The ConTeXt releases starting from 2007.01.12 have a few major changes that seem to catch some people unawares. 1. As of 2007.01.12, ConTeXt uses a 'pdftex' executable, no longer 'pdfetex'. This matches up with the release of pdftex 1.40, where there no longer is a separate 'pdfetex' executable. There are two ways out of this: - Apparently an old install of pdftex can still run, but only if you copy the 'pdfetex' executable to the name 'pdftex'. - But a better option is to update to pdftex 1.40, if that is possible for you. If your distribution does not offer a 1.40 package yet, you can try to compile and install pdftex yourself. The sources are available here: http://sarovar.org/project/showfiles.php?group_id=106 2. As of 2007.01.18, ConTeXt uses Latin Modern math fonts instead of computer modern. Unfortunately, most distributions still have a rather old version of the Latin Modern package, that does not have these fonts, so you may get 'Cannot find font ...' errors from TeX. The possible font names are 'rm-lmr', 'lmmi', 'lmsy' and 'lmex' (with a pointsize attached), so if you see such errors, you need to update our installation. If your distribution does not offer a latin modern 1.01 package yet, you can fetch the fonts from either CTAN or the Gust website. CTAN: http://www.ctan.org/tex-archive/fonts/lm/ GUST: http://www.gust.org.pl/projects/e-foundry/latin-modern 3. If you use XeTeX or aleph, there is yet another problem: the latin modern package does not itself contain dvipdfmx map files. This means (x)dvipdfmx will likely find the ones intended for pdftex instead, and it will generate a lot of warnings and errors. ConTeXt comes with a tool to generate dvipdfmx-type map files automatically, but you have to run it manually. It is a commandline tool, and you have to run it like so: ctxtools --dpx --force <texmfroot> You need to replace <texmfroot> with the toplevel texmf directory where the latin-modern font map files are. While on the commandline, you can type in kpsewhich lm-math.map If it returns /opt/tex/texmf-local/fonts/map/dvips/lm/lm-math.map, then the <texmfroot> is /opt/tex/texmf-local, and the full commandline is ctxtools --dpx --force /opt/tex/texmf-local I hope this explains most of the problems people have been having. If you or your distribution can not handle the required upgrades above, you should not update context at all, it will only give you grief (and broken output). In case this warning comes to late, all previous versions of ConTeXt are still available for download from the museum: https://foundry.supelec.fr/frs/?group_id=14 you probably want either 2007.01.12 or 2007.01.09.
