I am using luabind for binding my C++ classes to lua, I can get luabind and most lua functions to work, but if I try to use luaL_openlibs() I get:

undefined reference to 'luaL_openlibs'
collect2: ld returned 1 exit status

if I add -llua to the linker I get:

I built luabind myself because I could find no prebuilt mingw binaries.

    I figured it out.

    The problem was that I was linking to lua in a static library. I ended up downloading http://sourceforge.net/projects/luabinaries/files/5.1.4/Windows%20Libraries/lua5_1_4_Win32_dllw4_lib.zip, rebuilding luabind to link to that, and setting my project to link to it also.
