I downloaded the precompiled Eclipse Mars 4.5 in the official site here. Pseudocode

  1. Extract the tarball eclipse-jee-mars-2-linux-gtk-x86_64.tar.gz
  2. Move extracted Eclipse directory to some location where it can be at PATH.
  3. eclipse

Sjsam's contribution [so deprecate this way]

  1. Extract the tarball eclipse-jee-mars-2-linux-gtk-x86_64.tar.gz
  2. sudo mv eclipse /usr/local/bin/ where /usr/local/bin/ in my PATH
  3. sudo chmod 777 /usr/local/bin/
  4. eclipse


enter image description here

and in Terminal

Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.

The README does not have Unix installation instructions, just Windows one.

Additions to garethTheRed's answer

I did

sudo mv eclipse /usr/local/
sudo chmod -R 755 /usr/local/eclipse
sudo chown -R root:root /usr/local/eclipse
sudo ln -s /usr/local/eclipse/eclipse /usr/local/bin/eclipse


How can you have Eclipse 4.5 in your Path?


The problem is caused because you moved eclipse to a location outside the directory where you installed it.

Instead of moving eclipse to a directory in your path, create soft link to the executable. Assuming Eclipse is extracted within your home directory:

sudo ln -s /home/masi/eclipse/eclipse /usr/local/bin/eclipse

You can then run eclipse without prefixing it with the path.

  • I move eclipse directory to /usr/local/. Change permissions. Create the link. It seems other things use this workflow. – Léo Léopold Hertz 준영 May 3 '16 at 18:38
  • Please, see the end of the body for the completion of the case. Done! – Léo Léopold Hertz 준영 May 3 '16 at 18:44
  • I forgot that there is not easier approach than this. :D – sjsam May 3 '16 at 18:46

First of all moving eclipse binary to /usr/local/bin/ was a bad move.

Many executables need to to link to dynamic link libraries - usually called shared objects or .so - to work properly.

When you moved eclipse to /usr/local/bin you might have forgotten to move its corresponding shared objects to the same location and that is why you got :

The Eclipse executable was unable to locate its companion shared library

The solution here should be simple.

  1. Move Eclipse back to its original place.
  2. Run pwd to see the absolute name of the parent directory
  3. Append export PATH=$PATH:/folder/you/got/in/the/above/step to /home/your_user_name/.bashrc
  4. Start a new shell session
  5. Run eclipse
  • Did you install a precompiled package or did you compile eclipse from source? – sjsam May 3 '16 at 18:28
  • Where is eclipse located? – sjsam May 3 '16 at 18:29
  • You installed the .deb package to the Downloads folder? What is the file name? – sjsam May 3 '16 at 18:32
  • You are able to launch the binary from the Downloads right? – sjsam May 3 '16 at 18:35
