Ubuntu – Adding Eclipse CDT to an existing Eclipse JDT installation

11.04eclipse

I'm a Java developer who wants to start with C/C++ now. I have an Eclipse JDT installation, and today added the CDT feature plugin from inside Eclipse (Help->Install new software..-> and so on)

I restarted Eclipse, but I cannot see the C/C++ perspective and cannot create anything else than Java project. Googled on it, but found nothing special. Then I opened a terminal and did a sudo apt-get install eclipse-cdt. Started Eclipse again but nothing changed. I know there are downloadable Eclipse CDT packs, but I would not like to use them.

What should I do?

Using: Eclipse Galileo on Ubuntu 11.04

Try this: Window->Open perspective->Other... The CDT perspective should be there unless an error occurred while installing.

EDIT: Also make sure that Eclipse C/C++ Development Tools are listed in your installation details. Help->About Eclipse SDK->Installation details

I had similar problem before but with Java, the problem was fixed by doing

   eclipse -clean &

as it refreshes your workspace.

If it didn't work, you can try deleting workspace if it doesn't contain any valuable data and firing the above command again.

If you had the same issue I did, I suspect that your project builds but code-completion / code highlighting fails? I've just found some notes that may be useful. Here's what I did:

Project->Properties
C/C++ General
Paths and Symbols
select the appropriate language
Click "Add" and add the compiler-version specific directories

For language 'GNU C++' I added:

  /usr/include
  /usr/include/c++/4.6
  /usr/include/c++/4.6/bits
  /usr/include/i386-linux-gnu
  /usr/include/i386-linux-gnu/bits
  /usr/include/c++/4.6/debug
  /usr/include/c++/4.6/i686-linux-gnu
  /usr/include/c++/4.6/i686-linux-gnu/bits

For "GNU C" I added:

  /usr/include
  /usr/include/i386-linux-gnu
  /usr/include/i386-linux-gnu/bits

TBH, I don't think all the directories above are actually required (you could probably remove the 'bits' directories) but the list above worked for me at the time.

I am now using Eclipse Indigo (version 3.7.2) from eclipse.org and it automatically finds and adds the correct include directories. The list is different for me:

/usr/include/c++/4.6
/usr/include/c++/4.6/i686-linux-gnu
/usr/include/c++/4.6/backward
/usr/lib/gcc/i686-linux-gnu/4.6/include
/usr/local/include
/usr/lib/gcc/i686-linux-gnu/4.6/include-fixed
/usr/include/i386-linux-gnu
/usr/include

Clearly, only add the include directories that actually exist on your system ;-)
