Why can't I include or compile? [message #1826198]

I am having issues when trying to create a new C++ project. I recently decided to try virtualbox with Ubuntu on it to avoid using mingw. Everything was working fine when I just downloaded Eclipse and used it with mingw on my Windows machine, but now I downloaded it for Linux and can't get it figured out. For some reason it is working for C but not C++. I believe I have found the issue, but don't exactly know what to do to resolve it. When I go to properties > C/C++ General > Preprocessor Include, you can check a box that allows you to view built-in values. When I go into GNU C, there is a little triangle next to CDT GCC Built-in Compiler Settings that will show me what this contains. When I do the same thing for C++ there is no little triangle, so I am assuming that I have something configured improperly, but can't figure out how to fix it.
I have attached a couple pictures of my issue as well.

Check that you have installed the C++ toolkit into Ubuntu.

The best guess is to install the build-essential package, if
the tools are missing.

You can check by writing to the console:
which g++
g++ --version

Both should give meaningful responses, if the compiler is OK.
