使用pdflatex在C代码中编译LaTeX文件

2018-06-11 15:51:35

我正在编写为我写LaTeX文件的C代码。然后，我尝试在非交互模式下使用pdflatex编译文件（如我自动执行某个过程，并且不希望等待用户输入致命错误）。 LaTeX文件在./data/output_date.tex输出，我尝试使用该命令编译它

system("./pdflatex --interaction=nonstopmode --output-directory=data ./data/output_date.tex");

但是，我收到错误消息：

This is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009/Debian)

我似乎无法破译为什么我要紧急停止，尤其是因为当我从终端（与C可执行文件相同的文件夹）运行相同的确切命令时，LaTeX可以很好地编译为pdf。

有什么特别的，我必须做的，因为我打电话编译器作为从C代码的命令？

编辑：这是相应的.log文件的文本。它似乎只说“没有合法的 end found”，这让我感到困惑，因为我检查了源文件以确保我的 begin和 end匹配。

Here is how much of TeX's memory you used:

事实证明，在我尝试使用pdflatex命令进行编译之前，我需要关闭文件才能写入（在C代码中）。我在fclose命令后无意中添加了它。

我的猜测是我的排序在试图编译之前最后一次没有刷新缓冲区（这可能包括end{document} ），或者正在使用的文件以某种方式影响了pdflatex。
