Summary

There are a few important concepts to glean from this chapter:

• Size does matter when you’re working on embedded applications.

• To build the smallest, most reliable embedded application, you must either choose an embedded Linux distribution that matches your needs or roll your own.

• In all but the simplest applications, you should use the dynamic C libraries (shared libraries) as opposed to statically linking your executables.

• Don’t use -g or -static when compiling your executables for inclusion in an embedded application. Use -static only when there will be a single executable in your embedded system. Always use -Os optimization.
