XOs do not yet deal with WPA security automatically. They do not display WiFi access points that require WPA. Workaround at WPA Manual Setting.

Installing Eric3 IDE

Since the develop activity is still in progress I thought it would be worthwhile to get an existing Python IDE up and working. Eric3 [[1]] is a very complete IDE and more or less a standard I'm told in the Python world. There is a later version (Eric4) but the support for that doesn't seem to be available yet from YUM.

Below are the step by step instructions for getting Eric3 running on ship2.

  1. Go to the terminal activity and type su to get permissions to install software
  2. type: yum install qt and answer y to the prompt
  3. type: yum install PyQt and answer y to the prompt
  4. type: yum install PyQt-qscintilla and answer y to the prompt
  5. download eric-3.9.5.tar.gz[[2]]
  6. copy it to your /home/olpc directory. (If you download on a desktop, you can do this with sftp or a USB memory stick. See the appropriate instructions.) (ed: It would be good to put a link here...)
  7. type: tar xvf eric-3.9.5.tar.gz
  8. type: cd eric-3.9.5
  9. type: python install.py (Make sure you are still in super user mode or it will fail with a permission error. If you do this by accident its no big deal, just type su to return to super user mode and try again.)

Congratulations! You should now have eric3 installed. You can go ahead and delete the /home/olpc/eric-3.9.5 directory and the /home/olpc/eric-3.9.5.tar.gz files to free up some room.

To run eric3, type /usr/local/bin/eric3

Some Caveats

  • This is a basic Eric3 installation. You can get some advanced features by installing other supporting packages. Read the Eric3 docs for more information.
  • Eric3 is cramped on the default emulator screen size because it is not the full OLPC size. (Its only 1024x 768.) There are instructions elsewhere on the wiki for changing the screen size. (ed: It would be good to put a link here...)
  • On my emulator running ship2, this brings you up to 86% of the disk used, which I don't think is horrible. On my G1G1, it brings me to 45% utilization.
