[Tex/LaTex] Problems with opentype options under XeTeX

libertinelinuxxetex

I am new in the LaTeX world, so I don't understand everything about it, especially about the use of fonts.

I installed Linux Libertine font on my distribution (I use Gentoo, so I installed the package media-fonts/libertine-ttf), and it works fine using WYSIWYG programs, like LibreOffice. I can use the Linux Libertine O, Linux Libertine O C etc.

But, using XeTeX, it doesn't work. I set in my header

\setmainfont[Mapping=tex-text,Ligatures={Contextual, Common, Historical, Rare, Discretionary}]{Linux Libertine O}

But when I compile with xelatex, it says

(/usr/share/texmf-dist/tex/latex/carlisle/scalefnt.sty)kpathsea: Invalid fontname `Linux Libertine O', contains ' '


!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

! fontspec error: "font-not-found"
! 
! The font "Linux Libertine O" cannot be found.
! 
! See the fontspec documentation for further information.
! For immediate help type H .

When I remove the O in Linux Libertine O, it says:

What is wrong with my code (shown below)?

\documentclass[12pt]{lettre}

\usepackage{xunicode}
\usepackage{fontspec}
\usepackage{xltxtra}

\usepackage{lmodern}
\usepackage{eurosym}
\usepackage[frenchb]{babel}

%\setromanfont[Mapping=tex-text, Numbers=OldStyle, Ligatures=Historical]{Linux Libertine}
\setmainfont[Mapping=tex-text,Ligatures={Contextual, Common, Historical, Rare, Discretionary}]{Linux Libertine}

Best Answer

First, a font does not necessarily support all types of ligatures. Linux Libertine supports only (checked here) Ligatures={Common,Rare,Discretionary}.

The OpenType variant of Linux Libertine shipped with media-fonts/libertine-ttf works on an up-to-date Gentoo with TeX Live 2011. Another option is to install the dev-texlive/texlive-fontsextra package, which also contains the font. To use it and to be able to select it by name, run this command after installation:

eselect fontconfig enable 09-texlive.conf

This will allow all programs to access fonts installed in the TeX Live texmf tree.

Then this code will work as expected:

\documentclass{article}

\usepackage{fontspec}
\setmainfont[Mapping=tex-text,Ligatures={Common,Rare,Discretionary}]{Linux Libertine O}

\begin{document}

Hello World

\end{document}

Note: This was tested on TeX Live 2011. Gentoo has TeX Live 2010 as the stable version. If you keep experiencing problems, try upgrading to the newer version of TeX Live.
