Hello, Changing from emacs on WSL (linux on windows) to emacs on MS-Windows, I had to change in my org-mode files some paths from : "/mnt/d/path/to/file" to "d:/path/to/file/". Doing this breaks the export to LaTeX. Here is a minimum example org file showing the issue when exported (the lines of codes with columns after "#+LATEX_HEADER:" do not exports to the LaTeX file). Thanks in advance, Olivier #+LATEX_CLASS: article #+LATEX_CLASS_OPTIONS: [a4paper] #+LATEX_HEADER:\newcommand{\macroOne}{drive:/windows-path/to/file1} #+LATEX_HEADER:\newcommand{\macroTwo}{drive/windows-path/to/file1} #+LATEX_HEADER:\newcommand{\macroThree}{:nothing} #+LATEX_HEADER:anything:with:columns * Problem description This line of code does not export to =LaTeX= #+begin_example #+LATEX_HEADER:\newcommand{\macroOne}{drive:/windows-path/to/file1} #+end_example while this one #+begin_example #+LATEX_HEADER:\newcommand{\macroTwo}{drive/windows-path/to/file1} #+end_example is exported as expected with a line like this in the =LaTeX= file: #+begin_export latex \texttt{\MacroTwo} #+end_export It seems that the presence of any column (=:=) after =#+LATEX_HEADER:= breaks the export which is an issue on =MS-Windows= for defining paths.
