[c++] How do I install Eclipse with C++ in Ubuntu 12.10 (Quantal Quetzal)?

I just installed Ubuntu 12.10, and I tried to install Eclipse and C++, but I failed miserably.

I started with an installation from the Software Center, Eclipse worked, but only in Java. Then I started googling for installation guides and tutorials, but after hours of downloads and installations, the C++ in Eclipse still doesn't work.

So now I have two questions:

1. How do I clean up this mess?
   Actually, how do I know if there is a mess?
   According to the Ubuntu Software Center, Eclipse is installed and has three add-ons.
   How do I know if the other installations of other Eclipse versions/packagings overwrote each other or if I have multiple installations?

2. How do I install the latest version of Eclipse and C++ in Ubuntu 12.10?

I was in the same boat. Installed Eclipse, realized need CDT.

sudo apt-get install eclipse eclipse-cdt g++

This just adds the CDT package on top of existing installation - no un-installation etc. required.

I also tried http://www.eclipse.org/cdt/ in Ubuntu 12.04.2 LTS and works fine!

1. First, I downloaded it from www.eclipse.org/downloads/, choosing Eclipse IDE for C/C++ Developers.

2. I save the file somewhere, let´s say into my home directory. Open a console or terminal, and type:

   >>cd ~; tar xvzf eclipse*.tar.gz;

3. Remember for having Eclipse running in Linux, it is required a JVM, so download a jdk file e.g jdk-7u17-linux-i586.rpm (I cann´t post the link due to my low reputation) ... anyway

4. Install the .rpm file following http://www.wikihow.com/Install-Java-on-Linux

5. Find the path to the Java installation, by typing:

   >>which java

6. I got /usr/bin/java. To start up Eclipse, type:

   >>cd ~/eclipse; ./eclipse -vm /usr/bin/java

Also, once everything is installed, in the home directory, you can double-click the executable icon called eclipse, and then you´ll have it!. In case you like an icon, create a .desktop file in /usr/share/applications:

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

The .desktop file content is as follows:

[Desktop Entry]  
Name=Eclipse  
Type=Application  
Exec="This is the path of the eclipse executable on your machine"  
Terminal=false 
Icon="This is the path of the icon.xpm file on your machine"  
Comment=Integrated Development Environment  
NoDisplay=false  
Categories=Development;IDE  
Name[en]=eclipse.desktop  

Best luck!

http://www.eclipse.org/cdt/ ^Give that a try

I have not used the CDT for eclipse but I do use Eclipse Java for Ubuntu 12.04 and it works wonders.

I used (the suggested answer from above)

sudo apt-get install eclipse eclipse-cdt g++

but ONLY after then also doing

sudo eclipse -clean

Hope that also helps.
