A. SYSTEM REQUIREMENTS
The Java Runtime Environment (JRE) Version 1.5.X or higher is required
to run GCLAS. The latest version for Solaris, Linux, and Microsoft
Windows platforms can be downloaded from http://java.sun.com. For USGS
Solaris installations, the JRE is part of the standard Solaris 10 installation.
B. DISTRIBUTION FILE
The following distribution package (containing the software and
information files) is currently available for UNIX systems:
gclas_install1_05e.jar - For platforms with JRE 1.5.X or higher installed
C. DOCUMENTATION
An on-line help manual can be displayed by selecting Help Topics
from the GCLAS Help menu. A user's manual can be is available on the
Web at http://pubs.usgs.gov/tm/2006/tm4C1/.
D. INSTALLATION
The distribution file (gclas_install1_05e.jar) is a java installer. Type
"java -jar gclas_install1_05e.jar" to run it and then follow the instructions
given by the installer to complete the installation.
Thie installer creates the following directory structure (the contents of each
directory are shown to the right):
gclas1.05 files NOTICE.TXT and this README.TXT
`-----bin script to run GCLAS
`-----data example input data
`-----doc documentation files
`-----help file containing on-line help text
`-----lib class files and software libraries
`-----lib_data parameter and constituent files
`-----user working directory used by GCLAS shortcuts
After GCLAS has been installed, it can be executed by typing the full pathname of
the execution script in the bin subdirectory, for example:
/usr/opt/wrdapp/gclas1.05/bin/gclas
However, to make the software accessible from any directory, create a link to the
execution script, placing it in a directory that is included in each user's search
path. For example, if each user's search path consists of
/usr/bin:/usr/opt/bin:/usr/local/bin
using the command
ln -s /usr/opt/wrdapp/gclas1.05/bin/gclas /usr/local/bin/gclas
will make the program accessible from any directory without requiring the
full pathname of the executable.
Users with multiple installations of JRE should note that the execution
script will execute the first java command found by the operating system
in searching the directories contained in the user's search path (type
"which java" to see which command this is; type "java -version" to see
what version of the JRE it is). To execute a different java command,
uncomment and modify as appropriate the lines containing the JREHOME
variable in the execution script.
E. RUNNING THE PROGRAM
If the program has been installed in a directory included in the users'
PATH (as described above), the program can be executed with the command
"gclas". Otherwise, the full pathname of the execution script will need
to be typed.
See the "GETTING STARTED" text in the upper right-hand panel of the
GCLAS window and the on-line help for assistance with using GCLAS.
F. UNINSTALLING
To uninstall GCLAS, delete the gclas1.05 directory and all of its contents
and remove any links created to the execution script as described under
INSTALLING above.
