I have downloaded the related Eclipse .tar package from here to install on my 64 bit machine. I followed the instruction, but does not seem to work. How to install the Eclipse Neon/Mars for C/C++ on ubuntu 14.04.


Assuming you extracted the downloaded eclipse package and created a working eclipse.desktop launcher file, then your eclipse still needs at least an installed JRE (Java Runtime Environment) or an installed JDK (Java Development Kit - OpenJDK or OracleJDK) to work...

I would recommend you to install OracleJDK if you develop with Java as well, otherwise you only need the OracleJRE... I can post the instructions how to do this in a very clean way, if you need them...

Eclipse should locate your installed JRE/JDK automatically, if everything is installed properly... alternatively you can tell eclipse, where to find the JRE/JDK:

open the eclipse.ini file with gedit (in your extracted eclipse folder) and edit it as follows:



# add these lines ----------------------------------------
# --------------------------------------------------------



Replace 'path-to-jre-or-jdk-folder' with the real path on your computer and replace 'version' with the version number of your installed JRE/JDK...

  • Thanks .. I am not building it for java, so no need of JRE/JDK – Agaz Hussain Jun 8 '16 at 11:22
  • JRE is required for eclipse itself, you MUST install it! – Neni Jun 8 '16 at 11:27
  • Yes, you need a JRE to run eclipse, if you are not programming in Java you won't need the JDK, but the JRE is required. Check here eclipse.org/downloads in the lower right for the HINT – John Kirchner Jun 8 '16 at 11:28
