Deploy project without Midas.dll C++

I am trying to make it so I can deploy a firemonkey project which uses Midas.dll onto another machine without having to copy the DLL over as well. This article explains how to do this with a delphi project by including MidasLib in your uses clause like so:

program Project1;

uses
  MidasLib,
  Forms,
  Unit1 in 'Unit1.pas' {Form1};

I am not very familiar with delphi, but I assume that in C++ I would want to use an #include statement in places of the uses statement. Since MidasLib is a .pas file, I assume I am supposed to include Midas.hpp. However, even though I include Midas.hpp in the file that is using it, I still get an exception saying "Midas.dll not found."

How can I deploy my project without having to copy the Midas.dll file over with it?

Solution

  • You should also link the static library and call the RegisterMidasLib function:

    #include <Midas.hpp>

// or use the Project Manager's "Add to Project" option
#pragma comment(lib, "midas.lib")

extern "C" __stdcall DllGetDataSnapClassObject(REFCLSID, REFIID, void **);

void InitMidas() 
{
  #pragma startup InitMidas 254
  RegisterMidasLib(DllGetDataSnapClassObject);
}
