Here's the problem I've been having: in any lyx file which contains (in mathmode) a fraction or a sub or superscript, both View > pdflatex and File > Print produce an error message. (LyX/Mac, LyX 1.3.4, Mac 10.3.4) Ronald Florence has been very helpful, and he suggested that I read the help files on the use of -dbg and then start lyx from the command line with the appropriate debug parameter.
But I'm a tabla rasa as far as unix is concerned. And the LyX help files say almost nothing about -dbg, unless I've missed a section. And what is the appropriate debug parameter? Can someone spell out exactly what I need to do to follow Ronald's suggestion? Do I do whatever I do right after I have gotten LyX to produce a print or preview error message? I do at least know how to get to the Terminal on the Mac, and Ronald's HOWTO LyX/Mac page says for debugging that I can start LyX from the command line with /Applications/LyX.app/Contents/MacOS/LyX. Thanks, Bruce Pourciau
