== Debugging PARI/GP build errors ==
If the new pari spkg doesn't build, you should try building PARI/GP stand-alone (i.e. outside of Sage).
You should download [[http://cage.ugent.be/~jdemeyer/sage/pari-2.4.3.svn-12577.p3.spkg|pari-2.4.3.svn-12577.p3.spkg]]
and then type the following in a shell:
{{{
tar xjf pari-2.4.3.svn-12577.p3.spkg
cd pari-2.4.3.svn-12577.p3/src
./Configure --graphic=none
make gp
}}}
If this works, this is a bug in Sage's build process for PARI/GP.
If this gives errors, this indicates an upstream issue with PARI/GP.
In any case, any errors should be reported on the Sage trac.

 * Build issues on Fedora 13: see [[http://trac.sagemath.org/sage_trac/ticket/9722|9722]]

New version of PARI/GP: 2.4.3 svn-12577

Relevant tickets

  • 9343: PARI upgrade

  • 9591: genus2reduction

  • 9592: lcalc

  • 9722: PARI/GP build error on Fedora 13

Files

The above list also indicates the order in which to install the spkg's and patches. In particular, the genus2reduction spkg will not install without the new pari spkg.

For reviewers

  • Download sage-4.6.prealpha1.tar, which is a complete Sage distribution based on sage-4.5.3.alpha1. Just extract it, and type make. In this file, the following tickets have been merged:

    • 9343 (needs_work): PARI upgrade

    • 9591 (needs_review): genus2reduction

    • 9592 (needs_review): lcalc

    • 9750 (positive_review): Document that PARI no longer assumes more than GRH

    • 9636 (needs_review): Catch output from PARI in Sage

  • The main issue seems to be making sure it actually compiles.

    • Once it compiles, you can run the PARI/GP test suite by doing env SAGE_CHECK=yes ./sage -f pari-2.4.3.svn-12577.p3.spkg

  • For reference, these are the patches for the spkg's:

If the new pari spkg doesn't build, you should try building PARI/GP stand-alone (i.e. outside of Sage). You should download pari-2.4.3.svn-12577.p3.spkg and then type the following in a shell: 

tar xjf pari-2.4.3.svn-12577.p3.spkg
cd pari-2.4.3.svn-12577.p3/src
./Configure --graphic=none
make gp

If this works, this is a bug in Sage's build process for PARI/GP. If this gives errors, this indicates an upstream issue with PARI/GP. In any case, any errors should be reported on the Sage trac.

Known issues

  • It doesn't build on t2.math.washington.edu

    • jdemeyer: I will have a look at this once I get a working account on this machine.

  • Tuning (i.e. building with SAGE_PARI_tune=yes) is completely broken.

  • Build issues on Fedora 13: see 9722
