Wow, sometimes tough to find a good subject and issue description.
I am working on a dynamic binding to the mantle32.dll following DerelictGL and DerelictCl.
Functions in the mantle dll use structs as argument types. I would like to define those structs in a module derelict.mantle.types ( as in DerelictGL/CL ) and import them in module derelict.mantle.mantle. Module mantle does have the required hooks:

import DerelictUtil;
import some_other_module_which_needs_the_struct_definitions;

// struct definitions required
class DerelictMantleLoader : SharedLibLoader { ... }

Unfortunatelly I get an optilink error telling me that the required structs are undefined.
Putting the struct definitions back into module derelict.mantle.mantle does work, but this is not an option as it will lead to cross import issues later on. The structs are also required in module some_other_module_... and that module ( which should handle mantleExtensions ) must also be imported in module derelict.mantle.mantle.

I tried using opaque structs in module mantle which also didn't work.

How can I have those structs have defined in a different module than that which is linking to the dll ?

Is the source code so far up somewhere with the errors being given?

Nope, only a working version with all the stuff in one module, git DerelictMantle.

I created a version tag-less branch with the described issue and linker problem:
https://github.com/ParticlePeter/DerelictMantle/tree/ExtensionSupport

A test project using DerelictMantle can be found here:
