Eclipse Download and Installation

Eclipse Download and Installation
(for Python) Instructions

First download and Install Python and Java before installing Eclipse.

and then  do Preparation to installing Eclipse.

Eclipse: Version 4.4 (Luna)

The Eclipse download requires about 200 MB of disk space; keep it on your machine, in case you need to re-install Eclipse. When installed, Eclipse requires an additional 200 MB of disk space.

Downloading

1. Click EclipseThe following page will appear in your browser. In this handout we will download Eclipse Standard 4.4 for Windows 32 Bit; if your computer uses Windows, continue below; otherwise look for the pull-down list showing Windows and instead choose either Mac OS X (Cocoa) or Linux and then continue below.
   
   It is critical that Java, Python, and Eclipse are either all 32 Bit or are all 64 Bit (and only if your Machine/OS supports 64 Bit): I think it easiest to use 32 Bit for everything.
   
2. Click the Windows 32 Bit Operating System for your machine, under the heading Eclipse Standard 4.4 (right under Package Solutions).You will see the following page (don't worry about the name of the institution to the right of the big downward pointing arrow).
   
   
3. Click the orange DOWNLOAD button. The site named here, in orange to the right of the button: United States - Columbia University (http) is the random one chosen by the download page this time; yours may differ.This file should start downloading in your standard download folder, while showing a splash screen about donating to Eclipse. This file is about 200 Mb so it might take a while to download fully if you are on a slow internet connection (it took me about 5 minutes over a cable modem). Don't worry about the exact time as long as the download continues to make steady progress. In Chrome progress is shown on the bottom-left of the window, via the icon
   
   The file should appear as
   
   Terminate the window browsing the Eclipse download.
   
4. Move this file to a more permanent location, so that you can install Eclipse (and reinstall it later, if necessary).
5. Start the Installing instructions directly below.

Installing (for Python)

Python and Java should be installed before installing Eclipse

1. Unzip eclipse-standard-luna-R-win32.zip, the file that you just downloaded and moved.
   On my machine (running Windows 7), I can
   • Right-click the file.
   • Hover over the IZArc command from the menu of options.
   • Click Extract Here
   
   If you do not have IZArc or an equivalent unzipping program, here is the web site to download a free copy of IZarc.
   Unzipping this file creates a folder named eclipse; unzipping 200 MB can take a few minutes. You can leave this folder here or move it elsewhere on your hard disk. I recommend putting the downloaded file and resulting folder in the C:\Program Files\ directory.
   
2. Create a shortcut on your desktop to the eclipse.exe file in this eclipse folder: 
   On most Windows machines, you can
   • Right-press the file eclipse.exe
   • Drag it to the desktop.
   • Release the right button.
   • Click Create shortcut here
   Now you are ready to perform a one-time only setup of Eclipse on your machine.
   
3. Double-click the shortcut to Eclipse that you just created above.If the following Security Warning window appears
   
   
   
   • Uncheck the Always ask before opening this file checkbox
   • Click Run
   The following splash screen will appear
   
   and then a Workspace Launcher pop-up window will appear.
   
   In the Workspace text box, your name should appear between C:\Users\ and \workspace, instead of Pattis.
   Leave unchecked the Use this as the default and do not ask again box. Although you will use this same workspace for the entire quarter (checking projects in and out of it), it is best to see this Workspace Launcher pop-up window each time you start Eclipse, to remind you where your workspace is located.
   In fact, it is a good idea to create on your desktop a shortcut to your workspace folder; but you must click OK (see below) before Eclipse creates this folder and you can create a shortcut to it.
4. Click OK.Progress bars will appear as Eclipse loads.
   Eventually the Eclipse workbench will appear with a Welcome tab covering it.
   
   
5. Terminate (click X on) the Welcome tab.You will not see the Welcome tab when you start Eclipse again, after this first time.

    The Eclipse workbench will now have only the PyDev icon here and will look like
    
    
23. Locate the workspace folder created in step 3 (see C:\Users\yourname\workspace) and download the courselib.zip file into this workspace and unzip it there, producing the courselibfolder; it should should contain a bunch of Python module files (ending in .py). From time to time you will be asked to put other course-specific Python module files into this courselibfolder; these modules will be usable in all Python projects in Eclipse.
24. Inform Eclipse to use the courselib folder in all Python projects.
    • Select Window | Preferences.
    • Disclose PyDev by clicking the + in front of PyDev or double-clicking PyDev (after the +); the + changes to a -.
