I have installed Eclipse as following:

1 → Download eclipse-standard-kepler-SR2-linux-gtk-x86_64.tar.gz to my 14.04

enter image description here

2 → Extracted it using the command,

sudo tar -xvf eclipse-standard-kepler-SR2-linux-gtk-x86_64.tar.gz

3 → Moved eclipse to /opt/ using command,

sudo mv eclipse /opt/

4 → Created Icon(64x64) for eclipse using GIMP Image Editor.

5 → Installed gnome-panel using,

sudo apt-get install --no-install-recommends gnome-panel

6 → And Create Application by using,

sudo gnome-desktop-item-edit /usr/share/applications/ --create-new


7 → Select Icon,


8 → Select eclipse application for comment,

enter image description here

9 → Finally enter command and click OK.

enter image description here

I have given everything required, and the application created and showing,

enter image description here

But when I open this application it's not working.

(Note: I have created another one, because first one not worked, and now both not working. That why picture showing two eclipse.)

When I tried to open it in terminal, I got

bash: /opt/eclipse/eclipse: cannot execute binary file: Exec format error

Please tell me where the problem may occur ?

  • BTW you downloaded Kepler but called it Juno in shortcut. It might take displeasure =) – Danatela May 14 '14 at 11:58

If you get

/opt/eclipse/eclipse: cannot execute binary file: Exec format error

that usually means you use the wrong architecture. In this case you downloaded the 64bit version but should use the 32bit version of Eclipse.

  • use linux file utility to check architecture of the file: stackoverflow.com/a/2902650/304285 – amra Jul 10 '14 at 9:30

when I tried to open in terminal, am getting bash: /opt/eclipse/eclipse: cannot execute binary file: Exec format error

That means the file is damaged. Perhaps something went wrong while you did extraction. To ensure that it's not archive problem, follow these instructions:

  1. Every download has an associated link "(md5)" to a *.md5 file containing its MD5 checksum. Download this file into the same directory as the appropriate tar.gz file.

  2. Execute the command md5sum -c <gzfilename>.md5. The result <gzfilename>: OK is indicative of an intact download.

If the check succeeds, you have to remove Eclipse (sudo rm -rf /opt/eclipse) and repeat the steps you mentioned. If not, you have to redownload the file.
