sudo apt-get install texlive-latex-extra texlive-fonts-recommended
texlive-fonts-extra
sudo rm -rf gretl-git
git clone git://git.code.sf.net/p/gretl/git gretl-git
cd gretl-git
sudo apt-get build-dep gretl
./configure --prefix=/usr/local --enable-quiet-build --enable-openmp
--enable-build-doc --disable-json
make -j3
make pdfdocs
cli/gretlcli -v
sudo make install
sudo /sbin/ldconfig
gretl &"
