this doesn't work - with or without assignment (example2 = require("example2") or simple require("example2")) I got:

this works, I just missed change the type of return value of function (luaopen_example2), and it stayed as "void", without return value.

Now I think everything's clear.

See http://www.lua.org/manual/5.3/manual.html#pdf-require for explanation:

Your luaopen_example2() is a Lua function like any other and so is expected to push some values to the stack and return the number of values it pushed. You can set a global and not push anything (return 0), but in that case the require() call returns true. (However, the method you have now is preferred.)
