Error ThunkLoadFailed when loading a dll in a compiled m-File

Hello folks,

I am currently trying to compile an m-file which is utilizing a 64bit dll i wrote. I have already created the prototype file for using it with the syntax

[notfound,warnings] = loadlibrary('CCode/sharelib.dll',@prototype,'alias','sharelib');

where @prototype is the handle to the m-file i created from the corresponding h-file.

When executing the m-file from the matlab command-line, everything works fine. However, when i compile the code an try to run the executable, the windows command prompt yields the following error message:

    status =
         1
    message =

       ''
  Error using loadlibrary (line 419)
  Das angegebene Modul wurde nicht gefunden.

Error in Start_Raytracer (line 28)

MATLAB:loadlibrary:ThunkLoadFailed

The german sentence means "the specified module could not be found."

Especially the line "MATLAB:loadlibrary:ThunkLoadFailed" makes me wonder, because i cannot find that line neither inside the loadlibrary function nor on the internet.

Thanks alot for any comment on this =)

You need to add the thunk file to the executable produced. Use the -a option to mcc to include the thunk dll in the archive. Look in the directory containing the prototype file for the thunk file.

I thought I have tried so yesterday evening, but you have been absolutely right.

Thank you very much!
