I downloaded eclipse IDE (for C/C++ developers) to my Linux box running 14.04 LTS. I downloaded 64 bit version of JRE and 64 bit version of eclipse. I can run fine as root (sudo), but when I try to run from my user account, I get this log file output:

Just to clarify:
sudo eclipse works fine (eclipse at /opt/eclipse/eclipse is linked to /usr/local/bin).
eclipse and /opt/eclipse/eclipse return the error above.
What am I doing wrong? Any help would be greatly appreciated.



  • do you mean when you open executable from the directory of eclipse ? – Mohamed Slama May 31 '16 at 16:31
  • Hi Mohamed, I linked my eclipse executable at /opt/eclipse/eclipse to /usr/local/bin as suggested in Ubuntu documentation on eclipse install. /usr/local/bin is in my path. From my user space directory, I can do: %> sudo eclipse <<<< this works okay but %> eclipse <<< gives me the error – Vijay Kamarshi May 31 '16 at 16:34
  • please edit your question and append these information – Mohamed Slama May 31 '16 at 16:43
  • what's happen when you run /opt/eclipse/eclipse ? without sudo – Mohamed Slama May 31 '16 at 16:55
  • Running /opt/eclipse/eclipse without sudo - I get the same error – Vijay Kamarshi May 31 '16 at 16:59
