[Tex/LaTex] why does newtxmath fail to work with pdflatex and libertine

libertinenewtx

There seems to be some sort of incompatibility between the newtxmath package and libertine-legacy; the following code fails to compile:

 \documentclass{article}
 \usepackage[libertine]{newtxmath}
 \begin{document}
 $a = 1$
 \end{document}

when compiled through pdflatex, as it results in latex trying to find a Libertine-nu font which doesn't seem to exist:

kpathsea: Running mktextfm Libertine-nu
/usr/local/texlive/2012/texmf/web2c/mktexnam: Could not map source abbreviation L for Libertine-nu.
/usr/local/texlive/2012/texmf/web2c/mktexnam: Need to update /usr/local/texlive/2012/texmf-dist/fonts/map/fontname/special.map?
mktextfm: Running mf-nowin -progname=mf \mode:=ljfour; mag:=1; nonstopmode; input Libertine-nu

I installed the latest version of the package from: http://mirrors.ctan.org/install/fonts/libertine-legacy.tds.zip today, and haven't tried this before so don't know if it's a recent breakage or not.

I'd prefer to continue using pdflatex because the microtype package that doesn't seem to work well with lualatex or xelatex yet. Changing the package over to use the libertineotf package and compiling with xelatex does work.

I assume you are using the latest version of the newtx package, which comes with its own (stripped down) version of the Libertine font. Unfortunately, there's a small packaging error: The Libertine-nu.tfm file has the wrong case. Changing

/usr/local/texlive/2012/texmf-dist/fonts/tfm/public/newtx/libertine-nu.tfm

/usr/local/texlive/2012/texmf-dist/fonts/tfm/public/newtx/Libertine-nu.tfm

should do the trick.

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.

Update your system, then you'll get the old libertine package as libertine-legacy and then it should work as usual. The new package libertineotf supports only xetex and luatex.

With the current TeXLive and MiKTeX as of end of 2012 there is only one package libertine.sty which can be used as

\usepackage[options]{libertine}

Depending on what was run (xelatex/lualatex/pdflatex), it loads by itself the package fontspec or fontenc and does all the configuration.
