Step by step tutorial on how to use PARI/GP development version in Sage

This tutorial explains how to use a PARI/GP development version inside Sage.

Prerequisites

  1. We assume that your PARI/GP source code is at $PARI_ROOT
  2. You need to use a version of Sage compiled from source located at $SAGE_ROOT

Procedure

  1. Download the script pari_sage.sh

  2. Do 

    $ cd $PARI_ROOT
$ sage -sh                # starts Sage environment
$ source pari_build.sh    # reading pari_build.sh
$ pari_set_environment    # setting properly environment variables for compilation
$ pari_build              # building pari
$ pari_install            # installing pari

  3. Recompile cysignals 

    $ sage -f cysignals       # recompile cysignals (to be linked correctly against pari)

  4. Compile the last version of cypari 

    $ sage -pip install git+https://github.com/defeo/cypari2

  5. Recompile what needs to be 

    $ sage -br

Procedure to restore the standard PARI package in Sage 

  1. $ sage -f pari
$ sage -f cysignals
$ sage -f cypari
$ sage -br
