Ubuntu – Eclipse installation : unable-to-locate-companion-shared-library

eclipseeclipse-cdtsoftware installation

I install Eclipse Mars on Ubuntu 15.10 following this post:
How to install Eclipse using its installer

and lunch it after installation.

I install in /opt folder with sudo ./eclipse-inst

Than I create start Icon, following post, and after that when I try to start Eclipse I got this message:
eclipse-executable-launcher-error-unable-to-locate-companion-shared-library
and it is not possible to start it.

Any idea what happened?

this is message which I got when try to start from terminal:

../../../../root/.p2/pool/plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.300.v20150602-1417: cannot open shared object file: Permission denied
Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.

Hi,

actually when I try to start Eclipse from Terminal with sudo and type my password I can start it. It seems Eclipse doesn't have enough privileges to start.

Does anybody has idea what to do?
To change a privileges for the whole folder where Eclipse is installed?

Best Answer

I'm not sure it is the best solution, but it worked for me:

  • remove old installation
  • open installer as sudo
  • open the menu in the upper-right corner of the installer and turn OFF Bundle Pools
  • install the version you need
  • after the installation is completed go to /opt and change the owner of the eclipse folder. It should be something like sudo chown -R user:group eclipse_folder

The part I'm not sure about is the removal of the first installation. I just deleted the folder, but I'm afraid there's more stuff left behind in different folders.
