Installation Note:

You need the `pari.cfg' file from your PARI installation. Old version
of this file are named 'dft.Config.in' PARI installs this file
in "$prefix/lib/pari/pari.cfg"

Copy or link it to this directory and run

Run `./configure' .
Then run `make' .

Alternatively you can run
`./configure --with-paricfg=.../lib/pari/pari.cfg'
and `make'.

You can run `make check' for an automated check, but it requires
your environment being properly detected, so it may fail even if gp2c is
usable. Also the installed version of PARI/GP must match the version
of the source tree. The "args" check fails if the version mismatch.

You can try gp2c in this directory with the script ./gp2c .

You can do a "compile-and-run" with the script ./gp2c-run .

You can install gp2c and gp2c-run (in /usr/local/bin) by running
make install
as root.

configure support standard configure script options, for example to install 
in /usr/bin use

./configure --prefix=/usr

The following gp2c specific option are recognized.

  --enable-maintainer-mode enable make rules and dependencies not useful
                          (and sometimes confusing) to the casual installer.
  --with-perl  Perl is needed to compile the description files, but gp2c
               come with a precompiled description for PARI 2.1. so you can
	       use it without perl.  Default is to use perl if it is found.
	       You can specify the path to perl with --with-perl=PATH.
  --with-paricfg  PARI configuration is needed to build plug-ins.
               gp2c itself can be compiled without it, but gp2c-run and
               'make check' will not work.
               You must specify the path to the 'pari.cfg' file  with
               --with-paricfg=PATH.
