Installation

Attached is the compressed tar file with the source code and makefiles for the SAC package, v101.4. If you requested the Cygwin distribution, the file is sac-101.4-cygwin.tar.gz, otherwise it is sac-101.4.tar.gz.

The first step is to expand that file. If your version of tar has the "z" option, you can do this in one step:

   tar -xzf sac-101.4.tar.gz

or

   tar -xzf sac-101.4-cygwin.tar.gz

Otherwise you must first unzip and then untar the file. One way to do this is

   gzip -d -c sac-101.4.tar.gz | tar -xf -

or

   gzip -d -c sac-101.4-cygwin.tar.gz | tar -xf -

The result of this operation is the creation of a subdirectory ./sac-101.4 .

If you have a problem getting to this point, reply to this message with a detailed description of your problem.

File ./sac-101.4/License, contains the terms you agreed to honor when you requested SAC software. In particular you agreed NOT TO DISTRIBUTE the SAC Software.

Instructions for building the SAC package are in file ./sac-101.4/Readme.buildsac . As noted in that file, instructions for setting environmental variables for your system are given in file ./sac-101.4/README . The information in those two files should be all you should need to get the package running on your system.
