Following: https://github.com/KDE/okular/blob/master/ui/annotwindow.cpp I get: https://github.com/KDE/okular/blob/2aa006fa87240a89ff8446744ccd9f86a48c8dd0/ui/latexrenderer.cpp tempStream << "\ \\documentclass[" << fontSize << "pt]{article} \ \\usepackage{color} \ \\usepackage{amsmath,latexsym,amsfonts,amssymb,ulem} \ \\pagestyle{empty} \ \\begin{document} \ {\\color[rgb]{" << textColor.redF() << "," << textColor.greenF() << "," << textColor.blueF() << "} \ \\begin{eqnarray*} \ " << latexFormula << " \ \\end{eqnarray*}} \ \\end{document}"; So I searched for the packages (latex's); I thought I did the search with sid, but re-reading myself shows different. https://packages.debian.org/stretch/texlive-latex-base [amsmath.sty, latexsym.sty, color.sty] https://packages.debian.org/stretch/texlive-base [amsfont.sty] https://packages.debian.org/stretch/texlive-generic-recommended [ulem.sty] https://packages.debian.org/stretch/texlive-base [amssymb.sty] After the install of that I get: "Cannot find dvipng executable" There is a package of that name, so I installed it. And Voilà! Therefore, for the one thing it might be suitable to put those 5 packages in suggested dependencies of Okular; possibly through a "metapackage", for simplification, and ease of removal. However the resulting Okular behavior is far from satisfactory: The inline note shows only the latex code: in order to see the result of it, one has to first double click the inline note, and then to click on "render latex code"; which is far from providing an immediate and intuitive view of the formulas. However, again, that could be use to compensate that poppler's utf8 related bug: https://bugs.freedesktop.org/show_bug.cgi?id=65956 Provided one possibly modify https://github.com/KDE/okular/blob/2aa006fa87240a89ff8446744ccd9f86a48c8dd0/ui/latexrenderer.cpp through the addition of latex packages to render desired fonts; not sure it is so easy, but is is probably easier than fixing a 5 years old poppler's bug.
