What steps will reproduce the problem?
1. install plugin from http://petrituononen.com/llvm4eclipsecdt/update
2. restart eclipse
3. try to create a C++ project -> nothing happens (I mean no dialog box appears)
(alternate)3. try to edit prefs (window->preferences) by clicking on LLVM -> 
nothing happens

removing llvm4eclipsecdt plugin and restart restore ability to create c++ 
project.

What is the expected output? What do you see instead?
Ability to create c++ project and compile with llvm
Ability to set properties

What version of the product are you using? On what operating system?

Was just about to post this issue.

The reason for this error is API incompatibility due to change from 
PluginVersionIdentifier to Version in CDT 8.0

Nothing happens if user clicks workspace -> New -> C/C++ Project.
Or if user tries to create C/C++ project via New project wizard the following 
error message is produced:

Problem Occured

An error has occured. See error log for more details.

The solution:

 * To use Eclipse Indigo with CDT 8.0 (http://download.eclipse.org/tools/cdt/builds/)
 * I will soon create a version which is backward compatible with CDT 7.x and create a new category for it in the update site.

BTW Thanks for having time to write this issue down here.

I have created a temporary solution.

I created a new update site for CDT 7.x supported version. Feel free to test 
this plug-in now and if you find any issues please write them down here.

http://petrituononen.com/llvm4eclipsecdt/update_cdt7

I tried to create two features within update-site, but PDE tools didn't want to 
create generate a new jar for the another feature and also it doesn't update 
the references for newly generated files. I will be looking into it but writing 
update-site manually is too much.

It's better, i can now create a c++ project with llvm toolchain and access to 
prefs but now it fails with the well known "error: Cannot find library 
'stdc++'".

I was unable to add (value ignored) /usr/lib (where my libstdc++ is installed) 
in library search path.

Relevant (IMHO) error log message below :

Currently (at least) the plug-in is not supposed to find stdc++ library 
automatically due to the fact that it is located in different places on 
Windows, different Linux distributions and Mac.

What I suggest is to set LD_LIBRARY_PATH system environment variable to contain 
stdc++ library path.

Preference page needs some remodeling which might take some time because my 
current busy schedule.

The library search path error might now have been fixed. The reason is that 
methods related to adding library search paths to tool's option are not 
included in CDT 7.x. However the library search paths will still work because 
they are added to LD_LIBRARY_PATH environment variable in Eclipse.

I have now updated the update-site.

Now the official update-site 
(http://petrituononen.com/llvm4eclipsecdt/update)contains CDT 7 and CDT 8 
supported versions. This is now where the latest releases are found.

I will now close this issue because the original problem has been solved. If 
new issues should arise please open a new issue.
