使用pdflatex編譯C代碼中的LaTeX文件

Question

我正在編寫爲我編寫LaTeX文件的C代碼。然後，我嘗試在非交互模式下使用pdflatex編譯文件（如我自動執行某個過程，並且不希望等待用戶輸入致命錯誤）。該乳膠文件是./data/output_date.tex輸出，我試圖編譯它使用命令

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

不過，我得到錯誤信息：

<*> ./data/output_date.tex

我似乎無法破譯到底爲什麼我緊急停止，特別是因爲當我從終端（與C可執行文件相同的文件夾）運行相同的確切命令時，LaTeX可以很好地編譯爲pdf。

有什麼特殊的我必須做的，因爲我打電話編譯器作爲從C代碼的命令？

編輯：這是相應的.log文件的文本。它似乎只說「沒有合法的\ end found」，這讓我感到困惑，因爲我檢查了源文件以確保我的\ begin和\ end匹配。

Answer 1

原來我需要關閉該文件寫入（在C代碼）之前，我試圖與pdflatex命令編譯它。我無意中在fclose命令後面添加了它。

我的猜測是我的排序在試圖編譯之前最後一次沒有刷新緩衝區（其中包括\end{document}）或正在使用的文件以某種方式影響了pdflatex。
