This directory contains optional packages endowing PARI with extra capabilities.
To install a package from a source distribution:
================================================
extract it in the toplevel sources before running 'Configure', then run
'make install' as usual.
To install a package into an existing PARI/GP installation:
===========================================================
This is in particular the only method available to users of the Windows self-extracting binary.
Extract the archive anywhere you like, which will create a 'data' folder. Open 'data' and move the folder it contains (e.g. elldata) to the directory where the installer placed architecture independent files. The default destinations are
/usr/local/share/pari (Unix)
C:\Program Files\PARI (Win32)
You may delete the now empty 'data' folder.
List of available packages:
===========================
-- elldata: PARI version of the Elliptic curve data by J. E. Cremona,
, for use
with ellsearch, ellidentity and ellgenerators.
Requires PARI 2.2.11 or higher.
-- galdata: data needed by polgalois for degrees 8,9,10 and 11
Requires PARI 2.2.7 or higher.
-- seadata: needed by ellap for large primes. These polynomials were extracted
from the ECHIDNA databases and computed by David R. Kohel.
If you only need elliptic curves of cryptographic size, you may consider
seadata-small; this package is a (very small) subset of seadata that should
be suitable for primes up to 350 bits.
Both require PARI/GP 2.4.3 and up.
-- galpol: PARI package of the GALPOL database of polynomials defining Galois
extensions of the rationals, accessed by galoisgetpol.
Requires PARI/GP 2.4.3 and up.
-- nftables: repackaging of the historical 'megrez' number field tables (errors
fixed, 1/10th the size, easier to use). This package requires no
installation: extract it where desired and look at the README. Individual
tables from the package are available separately.
Requires PARI/GP 2.2.11 and up (need readvec).
