SNNS Version 3.0 Installation
**********************************************************************
Note that SNNS has not been tested extensively in different computer
environments and is a research tool with frequent substantial changes.
It should be obvious that we don't guarantee anything. We are also not
staffed to answer problems with SNNS or to fix bugs quickly.
SNNS currently runs on colour or black and white Sun-3, Sun-4 (SPARC)
systems under SunOS 4.1.1 with X-Windows X11R4 and X11R5 (Athena
widget set, twm, MIT fonts etc.) and under Sun OpenWindows 3.0. It
also runs on DecStations with MIPS R3000 Processor with X-Windows
X11R4 and X11R5. It has not been tested on out of the box DecStations
with DecWindows. It has also been tested recently on the IBM RS 6000
with AIX version 3.1. In general, the SNNS kernel will run on almost
any Unix system, while the graphical user interface might give
problems with systems which are not fully X11R4 (or X11R5) compatible.
To build SNNS in the directory in which you have moved it you first
have to generate the correct Makefiles for your machine architecture
and window system used. To do this, simply call the shell script
configure
This prompts you for information about the machine architecture and
the window system and builds all necessary makefiles with this
information. It uses templates found in the directory configuration
for this task. At the end of this script, you will be told about the
next step to build the simulator.
The next step to build the simulator is usually to build the kernel
and the graphical user interface with the command
build sim
or with the two commands
build kernel
build xgui
This script descends into the appropriate subdirectories and calls the
makefiles in these subdirectoires to compile all necessary source
files and link the object files into one executable file. The
executable is located in
<SNNS-dir.>/xgui/bin/<architecture>/xgui
where <SNNS-dir.> is the current SNNS directory and <architecture> is
the machine architecure, e.g. sun3, sparc, dec, rs6000, or others.
We usually build a symbolic link named 'snns' to point to this
executable if we often work on the same machine architecture.
ln -s xgui/bin/<architecture>/xgui snns
This link may also be placed in the user home directory (with the
proper path prefix to SNNS) or in a directory of binaries in the local
users' search path.
The simulator is then called simply with
snns
For further details about calling the simulator and working with the
graphical user interface see the user manual.
