The mcc compiler "Depfun error" when building dll with .NET-dependencies and Enumerations That Encapsulate Data

Question

I ran into problems in MATLAB R2010b when creating a DLL that uses .NET-integration and enumerations with encapsulate data.

Example:

There is a .NET Assembly which is used in MATLAB, let's call it "MyAssembly" (MyAssembly.dll).

There Matlab Enumerations Class "OpenMode"


classdef OpenMode
    methods
        function obj = OpenMode(netType)
            obj.Net = netType;
        end
    end
    properties
        Net
    end
    enumeration
        ReadOnly  (MyAssembly.OpenMode.ReadOnly)
        ReadWrite (MyAssembly.OpenMode.ReadWrite)
    end
end

This class uses the .NET enumeration: "MyAssembly.OpenMode" In such a way to access the .NET-enumeration via Matlab-enumeration (In my case it is necessary for cast types):


netElem = OpenMode.ReadOnly.Net;
cls = class(netElem)
cls = 
    MyAssembly.OpenMode

The Matlab-Function, that should be exported:


function retVal = MyFunction(inputs)
    NET.addAssembly('MyAssembly.dll');
    flag = OpenMode.ReadOnly;
    netFlag = flag.Net;
    % Some code...
end

Add .NET Assembly in Matlab (checking)
```
NET.addAssembly('MyAssembly.dll')
```

Try to compile the Dll:


mcc -B csharedlib:MyLib MyFunction

...and get the error:


Depfun error: 'Undefined variable "MyAssembly" or class "MyAssembly.OpenMode.ReadOnly".' 
??? Error using ==> mcc
Error executing mcc, return status = 1 (0x1).

The mcc compiler does not detect in code enumeration that "MyAssembly" exists, but here is a function will be compiled successfully:


    function retVal = MyFunction(inputs)
        netflag = MyAssembly.OpenMode.ReadOnly;
        % Some code...
    end

If you have faced similar problems in MATLAB and found a solution, please tell me what to do.

Thanks!

I seem to find solutions to these problems. It's not very elegant, but it works.

The mcc compiler has the option "-a filename". This option enables you to add the specified files for CTF archive. You want to add all the files that defines the enumeration using .NET Assemblies:

Example for my case:

mcc -B csharedlib:MyLib MyFunction -a OpenMode

...or in general:

mcc -B csharedlib:MyLib MyFunction -a projectdir/*.m

I have automated this with a build-script. This is so far the only solution that works.
