Not all Linux distributions come with the development headers installed.
You can either use Synaptic or run:
sudo apt-get install build-essential
Eclipse CDT works very for both build and debugging.
It will detect header files in the standard places.
You can do builds in different ways, either by supplying the Make file, or Eclipse can do the build for you.
This was released in July 2008 and may not be included in your Linux distribution yet. In order to install it manually: Download Google C++ Testing Framework
Here are the install instructions.
This will build the library files into /usr/local/lib. When you want to run a unit test you need to set the environment variable: LD_LIBRARY_PATH in order to pick up the shared lib.
export LD_LIBRARY_PATH=/usr/lib:/usr/local/lib
If running from Eclipse you have to set this in the Run Configuration dialog.
