After installing SP2 successfully, I found the following errors here Help->Software Updates->Manage
Configuration
Eclipse C/C++ Developement Tools 2.1.1:
Plug-in “org.eclipse.cdt.managedbuilder.core” version “2.1.1” referenced by this feature is missing.
Plug-in “org.eclipse.cdt.managedbuilder.ui” version “2.1.1” referenced by this feature is missing.
Is it normal? Although, until now everything works fine.
