Would like to setup programming environment in linux?
 

I am not sure where this message should be posted.
I am doing a project on grid computing implemented in Java.

To do this I need to run a tool called Globus that provide much of the grid services.

I have downloaded this tool but getting some problems. It tells me that I need to:

(1) download the Grid toolkit
(2) set GLOBUS_LOCATION in your environment, and run 'build_gpt'.

How do I do this latter bit, that is set the environment???? (I am using Linux.)

--------------------------------------------------

Here is the installation page. http://www.globus.org/gt2/install/index.html

Note only the begining of the page is relevant to me, that is upto header "Building from a Source Distribution".

It sounds like you just need to set an environment variable to the location of the 'Globus" tool.

Relpace the '/location/to/Globus' to the correct path to where Globus was installed.

You can run this in your current shell, and it it works then add it to your .profile or .bashrc to make it stick.

In linux what is the best (or the safest) way to uninstall programs?

In windows the applications usually have their own "Uninstall tools", if they don't one could use the "Windows COntrol Panel" to install and remove programs.

cd to the directory where u placed the source, then try to run
'make uninstall'. but some programs don´t support that.
if u have rpms then
'rpm -e program' to throw it away. (hope i don´t mix that better see man rpm)

I am setting up the Globus environment as mentioned on further reading, I have found out that I need to have Perl installed. From my understanding Perl is another programming language? (Or a scripting language).

Does Perl come with linux, because I think the gcc compiler does???

perl is almost always on a base install to start with. Knowing RedHat they've probably made it part of "Developer" package, blech. From the command line:

which perl

Should bring back /usr/bin/perl. "Which" will show you the location of anything executable as long as its in your path.

> which perl

/usr/bin/perl

How do I find the version, I need I think something like 5.**

type
perl -v
this will return the version
