Yes, that's right.  You need position-independent code on Linux x86-64 for
shared libraries, and also you shouldn't be linking the Lua core into the
shared library, so no -llua (and it seems customary to put the -shared at
the beginning of the command line, though I'm not sure whether it matters
for GCC); that's trying to pull in an entire static Lua, which is wrong.

You should read if you haven't
