LaTeX forum ⇒ General ⇒ Error on printing PDF document with pdflatex.exe

[dns_nx]

Hi,

I'm not quite sure, if this is the correct forum for my concern. If not please feel free to move it to the right one.

I need you help. The story's a little longer. So I'll start at the beginning. If you need more information about some points, please let me know, then I will add them.

I'm using pdflatex.exe to produce PDF files via a webpage.
That worked fine 2 or 3 years ago with the help of MiKTeX. Now I'm working again on this project and I did not work anymore. So I tried to install a new version of MiKTeX, but I wasn't able to install it on my Windows 10 computer (development machine). With MiKTeX portable I was able to produce PDF documents in the console, but it still did not work with my software. It did not even start to produce the PDF file (no .aux or .log files have been created).

So lately I switched to TeXLive.
Here I was also able to produce PDF documents in the console of Win10.
When I use the exact command in my software it starts to produce the PDF file (.aux and .log files being created), but it throws an error:

{d:/Program Files/TeXLive/texlive/2019/texmf-var/fonts/map/pdftex/updmap/pdftex
.map
!pdfTeX error: pdflatex.exe (file d:/Program Files/TeXLive/texlive/2019/texmf-v
ar/fonts/map/pdftex/updmap/pdftex.map): fflush() failed (Invalid argument)
==> Fatal error occurred, no output PDF file produced!

I tried to create a simple .tex file and run this in my software. The error is the same.
I tried it with this .tex file:

Code: [Select all] [Expand/Collapse] [Download] ({untitled.tex})

\documentclass{article}
 
\begin{document}
 
\title{Introduction to \LaTeX{}}
\author{Author's Name}
 
\maketitle
 
\begin{abstract}
The abstract text goes here.
\end{abstract}
 
\section{Introduction}
Here is the text of your introduction.
 
\begin{equation}
    \label{simple_equation}
    \alpha = \sqrt{ \beta }
\end{equation}
 
\subsection{Subsection Heading Here}
Write your subsection text here.
 
\section{Conclusion}
Write your conclusion here.
 
\end{document}

and the .log file is this:

The files are produced by a PHP page with the proc_open command:

$descriptorspec = array(
            0 => array("pipe", "r"),  // STDIN ist eine Pipe, von der das Child liest
            1 => array("pipe", "w"),  // STDOUT ist eine Pipe, in die das Child schreibt
            2 => array("file", "D:/Freigabe/error.txt", "a") // STDERR ist eine Datei,
                                                             // in die geschrieben wird
         );

         $env = null;

$process = proc_open('"' .$this->execute .'"', $descriptorspec, $pipes, $cwd, $env);

System Infos:
- Windows 10 Build 1809
- PHP 7.0.0

Is there any chance, that someone can give me hint about this issue? Or should I maybe post an issue on github.com?
Many thanks in advance!
