MRG Interactive Developments

The SpherePack package is under development at the Scientific Computing Division of the National Center for Atmospheric Research (NCAR) by John Adams and Paul Swarztrauber. The package contains a number of F77 subprograms that facilitate highly-accurate computational methods on the sphere. See the NCAR SpherePack homepage for more information about the latest version of the SpherePack package.

1. Fill out the SpherePack online order form and get your copy of the source code. Note that the licencing agreement is much more restrictive than you'll be used to with standard Open Source packages.
2. Unpack the source code using a command like tar -xf spherepack3.1.tar.
3. Move to the package base directory (for example: cd sphpk3.1.
4. Download a copy of the SpherePack Makefile (use left shift and click for download).
5. Build the SpherePack library using make lib.
6. Install the SpherePack library (libsphere.a) using make install PREFIX=/path/to/install. Where the /path/to/install in the example should be replaced by the prefix to the path where you'd like to install the library (default $HOME installs libsphere.a in $HOME/lib). For example, make install PREFIX=/usr/local will install the library as /usr/local/lib/libsphere.a.
7. Check that the installation worked by checking the contents of the newly-created library using ar -tf /path/to/install/lib/libsphere.a.
8. Run make clean to remove the local object files.
