Linking Error with Lua?

I've got a simple test application I'm trying to build in C++ with Lua (on Linux). The build line looks like this:

g++ -o"LuaTest" ./src/LuaTest.o -l/home/diego/lua-5.1.4/src/liblua.a

And it spits out this error:

/usr/bin/ld: cannot find -l/home/diego/lua-5.1.4/src/liblua.a

Which would be all well and good except that I'm staring liblua.a right in the face in that folder. I tried a similar configuration under Windows using MinGW and the Windows binaries for Lua and shockingly I get the exact same result, only it whines about lua51.lib or lua5.1.lib or whichever file I try.

What am I missing here?

If it matters here's the application:

extern "C"
{
#include "lua.h"
#include "lualib.h"
#include "lauxlib.h"
}

int main()
{
    return 0; //this really should compile -_-
}

Leave out the -l. It should be just:

g++ -o"LuaTest" ./src/LuaTest.o /home/diego/lua-5.1.4/src/liblua.a

The -l switch tells g++ to automatically add the lib and .a parts of the filename, and to look for it in the standard library directories - which you don't need here.
