PRE-REQUIREMENTS AND INSTALLATION PROCEDURE ON WINDOWS

It’s necessary to analise some essential requirements before to describe the steps used in order to create the r-gui executable file for Windows environment.

Firstly it is necessary that the GTK’s library and the software R are already installed on the machine. In order to avoid these problem it is necessary to visit this site:

            http://datasrv.soc.unitn.it/r-gui/files/windows

where it is possibile to find the R program and the GTK library. It is necessary to download and install on our machine these files.

Install all the files in the

            c:\Programmi\R\R-2.3.1

as will be suggested by the default installation procedure of R. Then it is necessary to install the GTK library. GTK is a library useful for the creation of our executable. Install everything in the folder:

            c:\GTK

Now, it is necessari to download Inno Setup and Phyton from this site:

            Inno Setup ---> http://jrsoftware.org/isdl.php#stable where it is possible to download

5.1.13 version.

            Python ---> http://www.python.org/download where it is possible to download the stable

version 2.4.4.

Other 6 packages are required in order to complete the installation. It is possible to find these packages at the follow link: http://datasrv.soc.unitn.it/r-gui/files/windows/devel_only

These packages are:

• py2exe-0.6.6.win32-py2.4.exe
• pycairo-1.0.2-1.win32-py2.4.exe
• pygobject-2.12.1-1.win32-py2.4.exe
• pygtk-2.10.1-1.win32-py2.4.exe
• rpy-1.0-RC1.win32-py2.4.exe
• pywin32-210.win32-py2.4.exe

By the installation of these packages some useful libraries will be installed in the

            c:\Python24\Lib\site-packages\

folder. Once the installation procedure is terminated it os necessary to download the files stored in the folder:

            http://r-gui.soc.unitn.it:10000/svn/r-gui/trunk/src

These files must be copied in a folder (for example c:\src) on the machine. Now, in the new directory there are the follow files or directory:

• COPYING.txt
• MANIFEST.in
• README.txt
• Bin
• copy-to-windows-dist
• data
• licence
• locales
• makefile
• r-gui.iss
• r-gui_post_install.py
• set-env.sh
• setup.py
• setup-windows.py

So far, the procedure used in order to install the R and the GTK library was described. Now, it is possible to find the step to step instruction for the generation of the r-gui-setup.exe.

1. Open a command prompt:

c:\Documents and Settings\Pippo>

2. Go to the working directory, in order to have:

c:\src>

3. At this point, run the following command:

c:\src>python setup-windows.py py2exe

With this command the setup-windows and py2exe executables will be run. Then it’ll create two folder:

• c:\src\dist

• c:\src\build

This command copys the files from  c:\src\data to c:\src\dist\data and the files from c:\src\copy-to-windows-dist to c:\src\dist.

4. Now, this folder contain all the files necessary to create the executable.

Finally it’s possible to use the Inno Setup for to generate the executable for windows. Run the Inno Setup and open the r-gui.iss file. This is in the c:\src folder, then launch the run function of Inno Setup. This function will create a new folder in c:\src, called Output; where is possible to find r-gui-setup.exe.

The Inno Setup by default will automatically run the r-gui-setup.exe, then if is all correct a new windows called GENERIC r-gui will be opened.
