You can only export from dlls. I don't know of any use case
where exporting from a executable would make sense. No, you
can't put common code into a executable and use that code from
dlls. Thats not how dlls are designed to work on windows.
If you absoutely still want to export from an executable you
can still use -L/EXPORT:"mangledSymbolName"
Is it possible to have circular dependencies between dlls?
No. You will get linker errors. Same as in C/C++.
Tips for doing dlls with dub?
Well, first my PR will have to get merged. Then you'll have to
wait until a release exists that actually has my changes and
then maybe there is support added in dub. Before that I think
trying to use dub to create dlls is wasted effort.
I am building a bridge between Delphi and D. At the moment the
executable is written in D and the Dll (Firemonkey UI) is written
in Delphi. But I think I want to enable also the other way
around. The D coding which is then located in the Dll should be
able to call Delphi methods located in the executable. The whole
idea idea is that all logic is written in D and you only use the
Framework (ui) and libraries Delphi provides.
I think this might be a valid use case for a Dll calling
functionality located in the exe.
Kind regards
