Hi there, Org beamer has proven to be an invaluable tool, I use it not only for preparing lecture notes but also for all my presentation - farewell powerpoint :) However, I recently upgraded my current version of org to 6.36. I love the new inline image, but their seem to be a bug in the latex export. It would appear that org-export-latex still does a good job in translating org files to latex, but for some reason I get an error when issue C-C C-e C-p . More specifically, pdftex.def Error: Option 'pdftex' requires pdfTex. What is interesting is 1) if I compile the resulting latex file from the command line everything works fine, 2) I don't get an error when there is an existing pdf file when I issue C-C C-e C-p, but the pdf doesn't get updated - it seems to skip the compiling stage if the pdf file is there. Does anybody have any suggestion how to resolve this issue. thanks M PS I am using carbon emac on snow leopard and mactex 2009 --- Marvin Doyley, PhD Assistant Professor of Electrical and Computer Engineering University of Rochester 413 Hopeman Engineering Building PO Box 270126 Rochester NY 14627 Tel:- +1)-585-275-3774 Fax: +1)-585-273-4919 http://www.ece.rochester.edu/projects/doyley_lab
