Eclipse display a problem with C++
From Klaus' wiki
On new virtual machines when you try to develop a C program Eclipse flags an error that it cannot find the C++ compiler.
You can fix it by opening a console i.e. Yakuake (Alt+F12) and install the C++ compiler.
On the commandline issue this command
]$ sudo yum install gcc-c++
Give your password and answer y to the question following and the gcc-c++ compiler will be installed.
