The ginac Portfile 54602 2009-07-30 06:29:03Z toby macports.org $

PortSystem 1.0

Name: GiNaC
Version: 1.4.4
Category: math
Platform: darwin
Maintainers: gwright
Description: GiNaC is Not a Computer algebra system
Long Description: Currently, GiNaC's capabilities include: 1. Very fast manipulation of large integers and rationals owing to the CLN library (for instance, it uses Karatsuba multiplication and Schoenhage-Strassen multiplication for very large integers). 2. Efficient handling of multivariate polynomials and rational functions. 3. Support for linear algebra includes symbolic matrices, vectors and solving equations. 4. Very fast heuristic polynomial GCD. 5. Many built in functions (sin, cos, atan, sinh, factorial, etc.) 6. Symbolic differentiation and series expansion of all built-in functions. 7. Several forms of output (also as optimized C++, for numerical postprocessing). 8. Memory-efficiency and -safety through the internal use of reference counting for all expressions.

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/ginac
%  sudo port install ginac  
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 ginac
--->  Verifying checksum for ginac
--->  Extracting ginac
--->  Configuring ginac
--->  Building ginac with target all

--->  Staging ginac into destroot

--->  Installing ginac

- 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 ginac with these commands:

%  man ginac
%  apropos ginac
%  which ginac
%  locate ginac
