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

Question

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?

Answer 1

There is a package called eclipse-cdt in the Ubuntu 12.10 repositories, this is what you want. If you haven't got g++ already, you need to install that as well, so all you need is:

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

Whether you messed up your system with your previous installation attempts depends heavily on how you did it. If you did it the safe way for trying out new packages not from repositories (ie, only installed in your home folder, no sudo s blindly copied from installation manuals...) you're definitely fine. Otherwise, you may well have thousands of stray files all over your file system now. In that case, run all uninstall scripts you can find for the things you installed, then install using apt-get and hope for the best.

Answer 2

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.

Answer 3

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 eg 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!

Answer 4

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.

Answer 5

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.
