It's not the code written in Lua that's compiled: Lua (written in C,
also valid as C++) is compiled, and that version doesn't seem to be
link-compatible with the compiled mysql.so library.  One possible
reason is that one was compiled as C and one was compiled as C++.
Without many more details of where all of these libraries have come
from and/or how they were built, and how you are linking, it's hard to
guess what's wrong.  From the ".so" filename and the paths we guess
that this is likely some Unix-like platform, but beyond that we're
speculating.
