Hello,

for 2 weeks or so I'm struggling with this phenomenon.

When I start eclipse as root I will see this error-message:
Could not open the editor: No editor descriptor for id org.eclipse.cdt.ui.editor.CEditor

I added the stack-trace at the end of this message.

And on the command-line I see this line:
W: Cannot inject update-sites, cannot find the correct config.


In eclipse I go Window->Preferences->General->Editors->File Associations
When I click at '*.c' and then Add eclipse presents me a list of internal editors but there is no C/C++-Editor.

This only happens wit C/C++-files, java works.

Confusingly it works when I start eclipse via the menu as a normal user.

When I try to install CDT it tells me that it will do nothing because CDT is already installed.

I start eclipse as root because I've modified some parts of the MySQL-server-code and I want to debug these parts (I've only got it working this way).

My system:
Ubuntu 10.04 64 bit
Eclipse Galileo

Any tips?
Do you need more information?

Hello,

this is what I did today (because Eclipse is unusab le now):

removed it from within Ubuntu and reinstalled it again -> no help

removed it from within Ubuntu and on the file-system I removed some directories:

- ~/worksapce/.metadata
- ~/.eclipse

so then I started to install eclipse again -> no help.

As you can see from the picture I added there is no choice of an C/C++-Editor when I try to open a file.


And when I try to install the missing software I get the follwoing message:

Cannot complete the request.  See the error log for details.
"Eclipse C/C++ Development Tools" will be ignored because it is already installed.
"Eclipse C/C++ Development Tools SDK" will be ignored because it is already installed.


What can I do now?

Thanks in advance.
AugustQ

How do you install Eclipse?
From Ubuntu's repository?

I recommend you to install Eclipse CDT from here.
Just download it and unpack where you want.

Hello Andrey,

Thanks! This solved most of my problems.

Now I'm struggling with errors that didn't happen before (in vio.c of the MySQL-sources) but I try to fix this by myself.
