Dear List, I am attempting to track down lack of instant preview for math equations. It seemed to be a random event between different files not working. I chalked it up to random incompatibilities between all the various classes and preambles, etc. However, even a new document doesn’t seem to work with a basic equation. I have looked into the tmp directory, and found that the previews are not generated because:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! ! Fatal fontspec error: "cannot-use-pdftex" ! ! The fontspec package requires either XeTeX or LuaTeX to function. ! ! You must change your typesetting engine to, e.g., "xelatex" or "lualatex" ! instead of plain "latex" or "pdflatex". ! ! See the fontspec documentation for further information. ! ! For immediate help type H <return>. !............................................... I have changed my graphics driver under Document settings to XeTeX, but no dice. I also changed my default engine to pdflatex, but I wouldn’t be able to compile my document then. I am using KOMA-Script and fontspec. All the equations render if I preview the ENTIRE document, but not the instant preview. Is there a setting I’m missing? Is this not possible unless everything is vanilla pdflatex? I can manually load the TeX file into Texmaker, compile under LuaLaTeX, and a nice preview pdf comes up. -- Respectfully, Robert Susmilch ==============The "gobbledygook" in this email is due to this email having been "signed" with PGP for security.
