The gmp Portfile 57676 2009-09-14 21:01:51Z toby macports.org $

PortSystem 1.0
PortGroup muniversal 1.0

Name: gmp
Version: 4.3.1
Revision: 1
Category: devel math
Maintainers: mcalhoun openmaintainer
Platform: darwin
Description: GNU multiple precision arithmetic library
Long Description: GNU MP is a library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers. It has a rich set of functions, and the functions have a regular interface. GNU MP is designed to be as fast as possible, both for small operands and for huge operands. The speed is achieved by using fullwords as the basic arithmetic type, by using fast algorithms, by carefully optimized assembly code for the most common inner loops for a lots of CPUs, and by a general emphasis on speed (instead of simplicity or elegance).

If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/gmp
%  sudo port install gmp  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching gmp
--->  Verifying checksum for gmp
--->  Extracting gmp
--->  Configuring gmp
--->  Building gmp with target all

--->  Staging gmp into destroot

--->  Installing gmp

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using gmp with these commands:

%  man gmp
%  apropos gmp
%  which gmp
%  locate gmp
