    Include required library file (should be libXML or similar) – Mohit Jain Feb 20 '15 at 12:36

    The compilation step is fine, your linker doesn't find the object files for (among others) the lua library. Add them to your project ( on the command line use `-L` and `-l` switches ). – collapsar Feb 20 '15 at 12:38

    [The top answer](http://stackoverflow.com/questions/12573816/what-is-an-undefined-reference-unresolved-external-symbol-error-and-how-do-i-fix) from that search box in your upper-right corner by by simply typing `[cpp] unresolved external` is pretty informative, and considerably more efficient than posting the wall of code in this question. – WhozCraig Feb 20 '15 at 12:41

Right click the project in the solution explorer.
Select "Linker"
In the "Input section" state the name of the Lua (and xml and all other libraries) library you are trying to use.
In the "General" section, specify where this library is in the "Additional Library Directories".

In general the "unresolved external" message has several previous answers: e.g. here. The specifics of the various IDEs vary slightly.
