XeLaTex : Math fonts : different output between Linux and Windows

Question

I'm using XeLaTeX to typeset documents containing maths, and using the Libertine font with some packages to get it working in math mode. However, whereas the output is fine on Windows with MikTex, the math font is broken when building in Linux with TeXlive. (see screenshots and MWE below)

\documentclass[12pt,a4paper]{article}

\usepackage[libertine,frenchmath]{newtxmath}
\usepackage{mathspec}
\usepackage{MnSymbol}\undef\mathdollar
\usepackage{libertine}
\begin{document}

These two $N$ N does not look the same on Linux.

\end{document}

Edit : Here is the log of Linux build :https://pastebin.com/raw/H0nrSPV4

And the Windows one : https://pastebin.com/raw/5ejbs5g1

Answer 1

You didn't show the log-files but only the terminal output so a lot details are missing. But your texsystem on linux is at least two years older than your miktex system and this quite probably is the reason for the difference.

Beside this: you are loading four package which are trying to change the math setup (newtxmath, mathspec, mnsymbol and through libertine fontspec). That is not a good idea. Better use only the one you really need and load fontspec with the no-math option, e.g.

\documentclass[12pt,a4paper]{article}

\usepackage[libertine,frenchmath]{newtxmath}
\usepackage{MnSymbol}

\usepackage[no-math]{fontspec}
\usepackage{libertine}
\begin{document}

These two $N$ N does not look the same on Linux.
