These errors suggest that the boost libraries were compiled with a different
version of gcc than the code that is trying to use them. Check which gcc 
version you used to build the boost libraries, and make sure that Code::Blocks
is configured to use the same gcc version.

These errors suggest that you need to link your program to the winsock32 
library. On the command line you would do this by adding the flag "-lws2_32" 
to the linker command. I'm not familiar with Code::Blocks, but presumably
there is a dialog somewhere where you can specify linker options.
