I made this little demo a few weeks back. It goes through the process of installing the CDT feature and then how you use it to build your first C programme. It starts from an already-installed Eclipse workbench–either the SDK or the Platform Runtime Binaries–and uses the Callisto Discovery Site to load the necessary features. I built the demo using Linux because you also need to have a C/C++ compiler installed and available before you can actually built a C programme.
I’ll apologise in advance for my lame C programming skills (the last time I wrote any C code as probably 1992).
Sorry… no sound. You’ll have to imagine my droning voice with this one.
