Why am I getting an 'undefined reference to 'boost::system::system_category()'' error during compilation?

Undefined Reference to 'boost::system::system_category()' during Compilation

While attempting to compile a program that utilizes Boost libraries on Ubuntu 11.10, you may encounter the following error:

undefined reference to boost::system::system_category()

Explanation:

This error arises when a program relies on the boost::system library, which is not explicitly linked during compilation.

Resolution:

To rectify this issue, you need to link your program against the boost_system library. If you're using gcc, append the following flag to your compiler command:

-lboost_system

This flag instructs the linker to include the boost_system library when compiling your program, resolving the undefined reference.
