VERSAMEDIUM andLinux-HOWTO

VERSAMEDIUM and Windows™

UNIX™ in Windows™

The Versamedium web client and the PGPLOT libraries which are used in the demonstration programs, are known to work well under UNIX based systems. Although seamless functionality can be achieved in Windows™. The best way that we found to make our demonstration programs work, was to install Ubuntu Live CD (less intrusive method), or alternatively install andLinux which is installed in the hard drive in the Windows™ file system. Both are Debian based distributions.

Ubuntu Live CD is in a 640 MegaBytes ISO image file (free download), that needs to be ``burned'' prior to boot from it in the cd tray.

andLinux is a 200 MegaBytes file (free download), that executes in Windows NT (32-bit) environment, which will install a minimal Debian based distro (XFCE version).

So in order to get the less intrusive unix environment installed in your computer, without ``perturbing'' the Windows OS computer we recomend to get Ubuntu Live CD or the andLinux package. Install either one and proceed as follows:

Ubuntu & andLinux Quick install

After installing either Linux distribution (above). There still, might be some extra packages required. So in order to get PGPLOT to work, complete the following steps:

sudo su

apt-get update

apt-get install gfortran

apt-get install libx11-6 libx11-dev x-window-system-core x-window-system xspecs libxtst6 psmisc build-essential

apt-get install libpng-dev

Go to the Pgplot installation page PGPLOT mini-howto.

andLinux detailed install

This mini-howto intends to be a guide through the installation and configuration of the andLinux Distribution package.

This instructions are not intended to substitute the original documentation in the andLinux install page.

I believe is the less intrusive instalation, go through the following set of self explanatory installation steps:

In the following step some info is missing in the picture below, just press the default options:

After installing, you will be prompted to restart your computer, do so. When you come back from the rebooting process, you will find a new Icon (shown below) in desktop, press it.

provide login name and password:

password:

sudo su

apt-get update

apt-get install gfortran

apt-get install libx11-6 libx11-dev x-window-system-core x-window-system xspecs libxtst6 psmisc build-essential

apt-get install libpng-dev

Invoking xfce from the terminal (as root) will show the panel with a xterm window, file manager, text editor, Web navigator, Synaptic (package manager) and Pulse Audio server app.

xfce4-panel

It is not recomended to run applications as root. So in order to run as a normal user, type Ctrl ^c to get out of the xfce4-panel. Then exit single user mode (root) by typing exit in the comand prompt.

Invoking xfce from the terminal (as normal user) will show the follofing panel with a xterm window, file manager and a Web navigator.

Note: Icons for the application in panel did not shown at the begining (in my installation). It should be farely easy to add an Icon, by right clicking the app.

xfce4-panel

From xfce panel invoke the xterm window. Now you are ready to test Versamedium's versa-client.

Download the versa-client distribution.

wget -c http://www.versamedium.com/geoinverse/distro_versa-ves-0.1.tar.gz

un-compress and un-package the file.

tar -zxvf distro_versa-ves-0.1.tar.gz

cd distro_versa-ves-0.1

gcc versa-client.c -lm -o versa-client

./versa-client www.versamedium.com 8888 0 test-matrix.dat

If everything is right? you should see this output log:

Do you want to test a complex application that uses versa-client?. You are ready to test Versamedium's versa-ves geophysical Vertical Electric Sounding demo.
