Kiegészítő LaTeX csomagok használata a Gummi, illetve TeX Live szerkesztőkben (Ubuntu 14.04)

Gummi TeX szerkesztő telepítése:

sudo apt-get install gummi 

Futassuk az alábbi két parancsot a Terminálból:

cd ~/.config/gummi
ln -s /usr/share/texmf-texlive

EN: Use additional LaTeX / TeX packages for Gummi or TeX Live on Ubuntu

1. Figure out where you installed the extra packages, from TeX Live or whatever else.  (For me, they live at /usr/share/texmf-texlive/.)
2. Create a symbolic link within the Gummi configuration folder to the TeXLive files:
   • cd ~/.config/gummi
     ln -s /usr/share/texmf-texlive
   Experimentation suggests that pointing Gummi at the top-level directory is sufficient for access to all of the subfolders.  If it fits the structure of your machine better, you could also copy or move the files — but I’d stick with a symbolic link unless you have a good plan in mind.
