Installation Note:
You need the `pari.cfg' file from your PARI installation.
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 do a "compile-and-debug" with the script ./gp2c-dbg .
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.
--with-paricfg-dbg=FILE gp2c-dbg is more useful with the debugging version
of PARI. You can specify the path to the 'pari.cfg' file of a
debugging version with --with-paricfg-dbg=PATH while still using
the optimised version with gp2c-run.
