SUMMARY Kile seems to ignore Quickbuild option. Even though I have selected Lualatex from "configure kile", it keeps trying to run pdflatex every time I save the tex file. The version is 2.9.93 (I supposed it is master but not sure) STEPS TO REPRODUCE 1. Settings->Configure Kile->Tools->Build->QuickBuild, select "LuaLatex+ViewPDF" 2. OK (confirm) 3. Press ctrl-s (save) OBSERVED RESULT LivePreview-PDFLatex (pdflatex) was run in both steps 2 and 3. Even though it probably should run lualatex instead. EXPECTED RESULT Should run lualatex instead SOFTWARE/OS VERSIONS Linux/KDE Plasma: Ubuntu 18.04/Gnome (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: 4.8.7 ADDITIONAL INFORMATION
