Hi all, A couple nights ago, my LyX magically stopped compiling my books. You know, the ones I sell for a living? Ugh!
I'll save you the hour long story of how I first traced the situation, and give you the stuff I found out. First, there's a document on your computer, put there by your texlive installation, called texlive-en.pdf. If you use a different language, substitute your language's suffix. Find it with your updated and locate commands, and find a way to bookmark it (perhaps with a shellscript or alias) If you're a Windows or Mac user, somewhere there's something similar for your Mikitext or whatever. Read it. Especially the chapter discussing the tlmgr program. Today's tlmgr is soooooo much better at maintaining your TeX configuration than anything in the past. If your stuff stops compiling (or even if you just want to keep everything up to date, I'd recommend: tlmgr update -all -dry-run If the results of that seem OK, I'd recommend a backup of your entire system, or for the sake of time and space, the entire tree under texlive, like /opt/texlive or /usr/local/texlive or whatever. It should have some directories named after years in it, and one called texmf-local. Anyway, once backed up, run this command: tlmgr update -all Then, if your stuff still doesn't compile, look at the error message, pick the most likely TeX package, and install it. For instance, if your compile gripes about no pstricks.sty, do this to get past that: tlmgr install pstricks texhash One of the worst things about LyX back in the day was getting your texlive situation squared away, but today doing so is much easier.
