Re: The specified module could not be found - LUA C API

Could You show symbols being exported from Your "pkghandler.dll" please? :)

It *MIGHT* be a linkage problem.

A bit different approach to building and loading *.DDL's for Lua is
described here:

(Notes section *MIGHT* be more useful then a bit outdated code example)
