I have just started Linux. I have a SBC(Atom processor) on which I have installed Ubuntu 12.04 and now I am trying to install Fortran IDE.

For which I have learnt that I need to install OpenJDK first, then Eclipse Juno and at last the Phortran plugin for Eclipse.

I have no Internet access so I had follow the below steps for manual installation.

  1. First download the eclipse tar.gz package (downloaded: eclipse-parallel-juno-linux-gtk.tar).

  2. Then right-click the eclipse tar.gz and choose the extract here option to extract the tar.gz package.You can also use the command line to extract the tar.gz package.

    # tar xzf eclipse-cpp-juno-linux-gtk.tar.gz

  3. Move to /opt/ folder.

    # mv eclipse /opt/

    Use sudo if the above command gives permission denied message.

    # sudo mv eclipse /opt/

  4. Create a desktop file and place it into /usr/share/applications

    # sudo gedit /usr/share/applications/eclipse.desktop

    and copy the following to the eclipse.desktop file

    [Desktop Entry]
Name=Eclipse 
Type=Application
Exec=/opt/eclipse/eclipse
Terminal=false
Icon=/opt/eclipse/icon.xpm
Comment=Integrated Development Environment
NoDisplay=false
Categories=Development;IDE
Name[en]=eclipse.desktop

  5. Create a symlink in /usr/local/bin using

    # cd /usr/local/bin
# sudo ln -s /opt/eclipse/eclipse

  6. Now its the time to launch eclipse.

    # /opt/eclipse/eclipse  -clean  &

Now at step 5, when I type the command sudo ln -s /opt/eclipse/eclipse , I get an this error message:

ln: Failed to create symbolic link './eclipse': File exists.

Please help me in resolving this.

Issue the following commands:

sudo rm /usr/local/bin/eclipse  
sudo ln -s /opt/eclipse/eclipse /usr/local/bin/eclipse

sudo /opt/eclipse/eclipse -clean &

If you have errors after these commands check this question (answer 2) askubuntu.com/questions/26632/how-to-install-eclipse

  • The first command deletes the actual eclipse binary, doesn't it? I think you meant sudo rm /usr/local/bin/eclipse. Then use sudo ln -s /opt/eclipse/eclipse eclipse. – phoibos Sep 27 '12 at 11:13
  • hi kamil & phoibos just tried as you have said, gives me same error msg: "ln: failed to create symbolic link 'eclipse': Fileexists" – VRU Sep 27 '12 at 13:07
  • Okay, just tried the command "sudo rm /usr/local/bin/eclipse" and it pop'd error msg: "rm: cannot remove '/usr/local/bin/eclipse': No such file or directory" – VRU Sep 27 '12 at 13:17
