This is the coda, all of it. Is it possible that I am running only one part of the full example?

The ones you need are system (most likely named something similar to boost_system-mgw44-mt-1_49) and ws2_32.
See here (http://wiki.codeblocks.org/index.php?title=FAQ-Compiling_(general)#Q:_I_would_like_to_compile_a_project_using_some_non-standard_libraries._How_can_I_indicate_to_CodeBlocks_that_these_libraries_and_include_files_exist.3F) if you do not know how to add libraries.
For future reference, that is not a full build log. A full build log would look something like this. (See my previous link for how to enable full command line logging.)
