编译崩溃

Question

该软件包french似乎已经过时了，最好使用 babel，它绝对是一个主线软件包。

删除后，\usepackage{french}还需要删除*.aux、*.toc、*.log 和 *.lot 文件，简而言之，就是 LaTeX 在获取 *.pdf 的过程中生成的辅助文件。*注意不要删除.tex 文件!!!

我在一些地方修改了你的代码：

\documentclass[a4paper]{report}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{graphicx}
\usepackage{fullpage}
\usepackage{eso-pic}
\usepackage{geometry}
\usepackage[english, french]{babel}
%\usepackage{french}
\usepackage[Glenn]{fncychap}
% Font style definition

\usepackage{blindtext}

% Interline setting
\renewcommand{\baselinestretch}{1.5}
\newcommand{\HRule}{\rule{\linewidth}{0.5mm}}
\newcommand{\blap}[1]{\vbox to 0pt{#1\vss}}
\newcommand\AtUpperLeftCorner[3]{%
  \put(\LenToUnit{#1},\LenToUnit{\dimexpr\paperheight-#2}){\blap{#3}}%
}
\newcommand\AtTopCenterPage[2]{%
  \put(\LenToUnit{.5\paperwidth},\LenToUnit{\dimexpr\paperheight-#1}){\blap{\hbox to 0pt{\hss#2\hss}}}%
}
\newcommand\AtUpperRightCorner[3]{%
  \put(\LenToUnit{\dimexpr\paperwidth-#1},\LenToUnit{\dimexpr\paperheight-#2}){\blap{\llap{#3}}}%
}

编译它（两次），您将获得英文和法文的摘要文本。

但是如果您的主要问题是如何在所有章节中自动更改语言，以便章节和章节的语言为英语，而文本为法语，请编辑您的问题。

texdoc packagename顺便说一句：您可以通过命令行（在 Windows 下：cmd.exe）获取每个软件包的手册。尝试一下texdoc -s packagename。
