Hi This is along the lines of the recent "lyx MacOS" thread. I have the same problem with the following symptoms:
(1) "View PDF (pdflatex)" does nothing (nothing means it grinds away a little bit and then does nothing. Lyx is responsive.) (2) "File -> Export -> PDF (pdflatex)" does nothing (produces no file in appropriate directory) (3) other methods of viewing do not work because the document uses "pdfpages" ....but.... (4) "File -> Export -> Latex" works, and produces a latex document that works when compiled in texshop using pdflatex. ....and more confusing.... (5) other documents that do NOT use "pdfpages" work as expected with pdflatex. So I know that my document isn't broken at any stage, and that my latex probably isn't broken either... I have tried fiddling as in the recent "lyx MacOS" thread (i.e. http://www.mail-archive.com/lyx-users@lists.lyx.org/msg42267.html ) with no success. I am using the most recent version of Lyx 1.3.6-2, on OS 10.4. I originally wrote this file in Lyx a few weeks ago... and it worked fine then too! TIA, David
