The latex file has problems installing/using the linguex package in a ucla thesis latex template (uclathes) (downloaded from GitHub). I inserted it in a preamble of the mother tex file, but it keeps sending `undefined sequence' errors every time I use it to gloss linguistic examples in the \exig. environment and I don't know how to fix it so that the error stops occurring. What is confusing is that all the examples in \exig. are perfectly printed out when compiled in the pdf despite the fact that they appear labeled as errors in tex document. Here is the (near minimal) code of the main tex file.   \documentclass [PhD] {uclathes} \usepackage{linguex}   \begin {document}   \chapter{Introduction}  \exig. Vazan je zadatak.\\ important be{\sc.prs.3sg} task\\ `A task is important.'   \end {document}

I am using pdflatex on a fresh (and current) MikTex 2.9 install with the following MWE:  \documentclass{article} \usepackage{animate} \begin{document}  Test \end{document}   Pdflatex throws the error:  Package: pdfbase 2017/03/23 v0.14 driver independent access to low-level PDF fe atures \g_pbs_page_int=\count175  ! Undefined control sequence. &lt;argument&gt; \luatexversion                            &lt;95 l.924 }   I have read the other posts containing the offending control sequence, especially  but the solutions offered there didn't help in my case.  This problem might have arisen with a recent MikTex update. I have now completely uninstalled, redownloaded, reinstalled and updates MikTex -- with no success.

I'm using this document class type  and I get the following error when I run it throgh XeLatex:  ! Undefined control sequence. &lt;recently read&gt; \str_case:nnn   l.72     ]{BookmanOldStyle}   I read and tried what the following post suggests (), but I still have no solution. The font files are in the right path and installed.  It was working perfectly last week, but reinstalled MikTex and started having this issue.  Any idea about what is happening?  The code I'm running is  \ifxetex     %% If the document is compiled with XeLaTeX, we load the TU Delft house     %% style fonts: Bookman Old Style (serif) for titles and Tahoma (sans-serif)     %% for text. Even if the nativefonts option was specified, we need these     %% fonts for the cover. \newfontfamily\tudrmfamily[     Path = fonts/,     Extension = .ttf,     BoldFont = *-Bold,     ItalicFont = *-Italic,     BoldItalicFont = *-BoldItalic ]{BookmanOldStyle}

I recently updated my operating system from Ubuntu 13.04 to Ubuntu 13.10. Since then, I am facing difficulties compiling my TeX code in which the french babel package is called. Please note that all my sources were compiling very fine before the system upgrade. However, now, given the following header:   \usepackage[francais]{babel}  I receive the following error:  ! Package babel Error: Unknown option `francais'. Either you misspelled it   What should I do? Please note that if I remove this part of code (\usepackage[francais]{babel}), everything is compiling well. I also tried it with french, and I receive the same result. Thank you in advance for your help.  MINIMUM WORKING EXAMPLE : \documentclass[11pt,a4paper]{article} \usepackage[utf8]{inputenc} \usepackage[francais]{babel} \usepackage[T1]{fontenc} \usepackage{amsmath} \usepackage{amsfonts} \usepackage{amssymb}  \begin{document} This is a MINIMUM WORKING EXAMPLE. \end{document}   !

Consider the following MWE:  \documentclass{scrreprt}  \usepackage{textcase}  \RequirePackage{listings} \usepackage[american]{babel}  \begin{document}     \MakeTextLowercase{A~B} \end{document}   LaTeX fails with the error  ! Undefined control sequence. &lt;to be read again&gt; az                      b l.9     \MakeTextLowercase{A~B}  ?    The error seems to lie in the combination of MakeTextLowercase, the listings package and the tilde. Whenever I remove any of these three components, everything works fine. Does anyone have a clue where the problem is?

I'm completely new to LaTeX. I'm using MiKTeX 2.9 (r.c29723a). When I launch TeXworks and try to compile , I receive the following error:  ... (C:\Tools\MiKTeX\tex\latex\biblatex\lbx\russian.lbx ! Package keyval Error: langjapanese undefined.   By clicking on the error message I jump to the closing brace of "\DeclareBibliographyStrings{%" in "russian.lbx", but this "key-value table" does have a "langjapanese" entry in it:  langjapanese   = {{японский}{яп\adddot}},   Am I missing something obvious here?

Usually I have no problem with babel and !:, and I don't use shortandoff-on switch. But since I made a command using !#1 parameter, the problem comes up again.  The same synthax used outside the command work fine, but in the command I get the error message :  ! Package tikz Error: + or - expected.  How to solve the problem without using the shortandoff-on switch ?  \documentclass[french,a4paper]{article} \RequirePackage{etex} \RequirePackage[utf8]{inputenc} \RequirePackage[T1]{fontenc} \RequirePackage{fourier}  \RequirePackage{tikz} \usetikzlibrary{calc,intersections}  %%%%%%%%%%%%%%%%%%%%%% %%%% Francisation %%%% %%%%%%%%%%%%%%%%%%%%%%  \RequirePackage{babel}  %%%%%%%%%%%%%%%%%%% ---------------------------------------- %%%% Géométrie %%%% %%%%%%%%%%%%%%%%%%%-----------------------------------------      % #1 option du path     % #2 premier point     % #3 second point     % #4 longueur dans un sens     % #5 longueur dans l'autre     % défini Mil#1#2 \newcommand{\Med}[5][]{%     \path[#1,name path=Med#2#3] ($(#2)!.5!(#3)$) node (Mil#2#3) {}      ($(Mil#2#3)!#4!90:(#3)$) -- ($(Mil#2#3)!#5!270:(#3)$) ; }  \tikzset{small dot/.style={fill=black,circle,scale=0.3}}  \begin{document}  %\shorthandoff{:!} \begin{tikzpicture}  \coordinate[label=below left:$A$] (A) at (0,0) ; \coordinate[label=below right:$B$] (B) at (4,0) ;  \draw (A)--(B) ;  %\Med[draw]{A}{B}{1}{1} ;  \draw($(A)!.5!(B)$) node (MilAB) {}      ($(MilAB)!1!90:(B)$) -- ($(MilAB)!1!270:(B)$) ;   \end{tikzpicture} %\shorthandon{:!}  \end{document}

Very new to Tex. Trying to get the most basic doc to work. Not matter what I do I always get an "Undefined control sequence" at line 1 of my document. As of now, I am only trying to build the following:  \documentclass{article} \begin{document} This is a test of the article \end{document}   Full error is:  This is pdfTeX, Version 3.1415926-2.5-1.40.14 (TeX Live 2013)  restricted \write18 enabled. entering extended mode (./example.tex ! Undefined control sequence. l.1 \documentclass                   {article} ?   I have tried many other variations, including \usepackage directives that people mentioned - nothing every varies.

(FYI I am new to LaTeX)  I'm trying to compile a TeX document that someone else has given me. I had BasicTex installed, and it didn't seem to work. My friend said he uses TeX Live, so I tried installing that but I get the same error after typing pdftex document.tex:  ! Undefined control sequence. l.1 \documentclass                   [final,hyperref={pdfpagelabels=false}]{beamer}   I'm guessing that means the distribution I have installed does not support this tag, is that right?  How can I find out which distribution I should install?

(my first question here) I'm using xelatex to compile this code:  \documentclass{book} \usepackage{fontspec}  \begin{document}  %This is a Greek text ``Ελλάδα'' text  \end{document}   and receive this error :  ("C:\Program Files\MiKTeX 2.9\tex\latex\fontspec\fontspec.cfg") !
