\begin{frame}[fragile]{Introduction}
This talk focuses on the current development version of the PARI library
({\textcolor{blue}{2.12.*}}), available from our GIT repository, see
\begin{center}
\gpurl{http://pari.math.u-bordeaux.fr/anongit.html}
\end{center}
The text of this talk is available in the files \kbd{sources.*} in
\begin{center}
\gpurl{http://pari.math.u-bordeaux.fr/Events/PARI2019/talks/}
\end{center}
\end{frame}

\begin{frame}[fragile]{Windows users}
Download a precompiled 64bit installer \kbd{Pari64-2-12-0.A2019.exe} or
32bit binary \kbd{Pari32-2-12-0.A2019.exe} from
\begin{center}
\gpurl{http://pari.math.u-bordeaux.fr/pub/pari/windows/snapshots/}
\end{center}
Also available are precompiled 64bit binary \kbd{gp64-gmp-git*.exe} or
32bit binary \kbd{gp32-gmp-git*.exe}.
\end{frame}

\begin{frame}[fragile]{Mac OS users}
Download a precompiled DMG \kbd{PariGP-full-2.12.0.A2019.dmg} or
\kbd{PariGP-full-2.12.0.A2019-pthread.dmg} from
\begin{center}
\gpurl{http://pari.math.u-bordeaux.fr/pub/pari/mac/snapshots/}
\end{center}
on some system, you need to right-click on the icon and select open,
so that you can bypass the security check.

Also are precompiled binary \kbd{gp-git*-osx}.
\end{frame}

\begin{frame}[fragile]{Linux}
To install all the packages required to build pari from source:

Debian/Ubuntu
\begin{verbatim}
sudo apt-get build-dep pari
sudo apt-get install libreadline-dev libgmp-dev
\end{verbatim}
Fedora
\begin{verbatim}
sudo dnf install readline-devel gmp-devel
\end{verbatim}

If you want to use git, also do

Debian/Ubuntu
\begin{verbatim}
sudo apt-get install git bison automake autoconf
\end{verbatim}

Fedora
\begin{verbatim}
sudo dnf install git bison automake autoconf
\end{verbatim}
\end{frame}

\begin{frame}[fragile]{From source with GIT}
Clone the PARI repository with GIT ($\sim150$MB).
\small
\begin{verbatim}
git clone http://pari.math.u-bordeaux.fr/git/pari.git
cd pari
\end{verbatim}
\end{frame}

\begin{frame}[fragile]{From source without GIT}
Download \kbd{pari-2.12.0.A2019.tar.gz} from
\begin{center}
\gpurl{http://pari.math.u-bordeaux.fr/pub/pari/snapshots/}
\end{center}
and unpack it
\begin{verbatim}
tar xf pari-2.12*.tar.gz
cd pari-2.12*
\end{verbatim}
\end{frame}

\begin{frame}[fragile]{PARI compilation}
\begin{verbatim}
./Configure --prefix=GPDIR --mt=pthread 
make -j4 gp
make doc
make statest-all
make install
make install-bin-sta
./Configure --prefix=GPDIR.dbg -g
make -j4 gp.dbg
make install -C Olinux-x86_64.dbg
GPDIR/bin/gp
\end{verbatim}
\end{frame}

\begin{frame}[fragile]{Optional PARI packages}
To install optional PARI packages from
\url{https://pari.math.u-bordeaux.fr/packages.html}
\begin{verbatim}
wget https://pari.math.u-bordeaux.fr/\
pub/pari/packages/galdata.tgz
tar xf galdata.tgz
wget https://pari.math.u-bordeaux.fr/\
pub/pari/packages/elldata.tgz
tar xf elldata.tgz
wget https://pari.math.u-bordeaux.fr/\
pub/pari/packages/galpol.tgz
tar xf galpol.tgz
wget https://pari.math.u-bordeaux.fr/\
pub/pari/packages/seadata.tgz
tar xf seadata.tgz
make install-data
\end{verbatim}
\end{frame}

\begin{frame}[fragile]{GP configuration}
Create and customize \verb!~/.gprc!.  Add
\begin{verbatim}
histfile = "~/.gp_history"
colors = "lightbg" \\ or "darkbg"
lines = 40
parisizemax = 4G \\ or the maximum amount of memory 
                 \\ GP can use (important)
threadsizemax = 1G
read "~/.gprc.gp"
\end{verbatim}
Create an empty file \verb!~/.gprc.gp!
\end{frame}

\begin{frame}[fragile]{GP2C compilation}
With GIT (and automake, autoconf):
{\small
\begin{verbatim}
git clone http://pari.math.u-bordeaux.fr/git/gp2c.git
cd gp2c
./autogen.sh
\end{verbatim}
}
Without GIT: download GP2C from
\gpurl{http://pari.math.u-bordeaux.fr/download.html\#gp2c}
\begin{verbatim}
tar xf gp2c-0.0.11pl1.tar.gz
cd gp2c-0.0.10pl1
\end{verbatim}
\end{frame}
\begin{frame}[fragile]{GP2C compilation}
\small
\begin{verbatim}
./configure --prefix=$PWD/../GPDIR \
     --with-paricfg=../GPDIR/lib/pari/pari.cfg \
     --with-paricfg.dbg=../GPDIR.dbg/lib/pari/pari.cfg
make check
make install
cd ..
GPDIR/bin/gp2c -v
\end{verbatim}
