Optional PARI/GP packages
This page lists all optional PARI/GP packages made available by the PARI
group. These packages use up a nonnegligible amount of disk space and will be
useless for most users, hence they are distributed separately and maintained
independently. They are rarely upgraded so most of them will only be
downloaded once. All packages are © the PARI group, distributed under
the terms of the GNU General Public License (GPL version 2 or any later
version).
Installation
A. To use a package with the daily Windows GP binary
Simply extract the archive in same folder as gp.exe (this will create a
'data' subfolder).
B. To install a package from a source distribution.
Extract the archive
in the toplevel pari directory before running ./Configure . Then
run make install as usual.
In order to fully test the distribution before installing, you can follow
the following threestep procedure
make installdata , which will only install the packages
extracted in the toplevel pari directory as above, and nothing else.
make testall will fully test the distribution, including
the newly installed packages.
make install to fully install the new distribution.
Of course, if the needed packages are already installed on this particular
machine, you can omit the first step. If some packages are in fact missing,
the second step will output warnings of the form
Skipping testname: optional package packagename
not installed .
If you need the corresponding feature, you can then install the needed
package.
C. To install a package into an existing PARI/GP installation.
This is in particular the only method available to users of the Windows
selfextracting binary.
 Type
default(datadir) in the gp interpreter to determine the
directory where it expects its architecture independent files.
 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 datadir determined above.
 You may delete the now empty
'data' folder.
D. To test whether a package is correctly installed.
 If you compile PARI/GP from source,
make testall .
 Here are sample commands that will fail if the package is not
available
\\ package: elldata
ellinit("11a1")
\\ package: galpol
galoisgetpol(8)
\\ package: seadata
ellmodulareqn(11)
\\ package: galdata
polgalois(x^82)
