Problems with Lua's loadlib

Original Post

Jul 7, 2006 at 11:30 PM

I have a DLL with a funciton declared with __declspec(dllexport) and extern "C", called foo. when I try typing the following in the Lua interpreter: loadlib('mydll.dll', 'foo')(); I get the following: stdin:1: attempt to call a null value stack traceback: stdin:1: in main chunk [C]: ? What am I doing wrong?

I'd say it's pretty obvious; the loadlib call is failing, so you get a null value, then you treat it as a function. The real question is, why is it failing? Is the DLL is in the program's directory, or your current working directory (if they differ)? Can you get the example at http://lua-users.org/wiki/CreatingBinaryExtensionModules to work?

Thanks for the link, I was using lua as a static lib not a dll. Thanks again, rating++.
