Which package should I download to compile C++0x code

[Erandros]

Hi, I'm new to Linux Forums.
OS is Ubuntu 10.04.
I need to compile some C++ code with -std=c++0x flag. But compiling doesn't work because I need 4.6.1 version.
Now, when I go to Gnu's ftp, I see two different packages:

gcc-4.6.1   
gcc-g++-4.6.1

Knowing that I need to compile C++0x code, which one should I download, and how do I install it/them?
I already installed these libraries (gmp, mpc and mpfr).
Thanks in advance.

The raw gcc package is the C compiler, and the g++ package is the C++ compiler. I think if you install the g++ package, the gcc package will be automatically installed as a dependency. In any case, the g++ package will let you do C++0x compatible code compilation.
