LuaJIT + shared library using iostream header = Undefined symbols.

Hi, everyone.
I'm trying out LuaJIT's FFI module. I'm not using a host program, but
importing a shared library using ffi.load instead, and running Lua code
using the `luajit' command.
However I'm getting undefined symbol errors loading my shared lib, like
this one:
$ luajit main.lua
luajit: main.lua:2: ./lunar.so: undefined symbol: _ZNSt8ios_base4InitD1Ev
stack traceback:
[C]: in function 'load'
main.lua:2: in main chunk
[C]: at 0x004049c0
More information:
- LuaJIT version: 2.0.3.
- GCC version: 4.6.3 (used to compile both LuaJIT and my shared library).
- Shared library GCC invocation: `gcc -shared -fPIC -Wall lunar.cpp -o
lunar.so'.
- Lua program invocation: `luajit main.lua'.
- main.lua / lunar.cpp sources and invocation strace:
gist.github.com/n2liquid/a71d086d38afae3dd6dc.
I really couldn't find information about this searching the web (still a
newb, so I probably don't know how to search properly). Most Q&As revolved
around using a C host program, but like I said, that's not my case.
If I simply remove `#include <iostream>' from lunar.cpp, it works just fine.
Can someone please help?
Atenciosamente / Sincerely,
Guilherme Prá Vieira
