MCC compiler "Internal Error: Could not determine class of method" - matlab

Question

I have Matlab script that I am trying to compile as an executable that will run on a headless server as part of a large batch process. The script calls functions and classes written by several non-programmers (scientists) over the span of more than a decade, and I am having a difficult time getting it to compile.
The script will run in a Matlab instance, but MCC gives me an error that I do not quite understand:
Compiler version: 5.1 (R2014a)
Dependency analysis by REQUIREMENTS.
Error using matlab.depfun.internal.MatlabSymbol/proxy (line 405)
Internal1 Error: Could not determine class of method
"/home/me/MyCode/#tsd/Data.m". Number of classes checked:
17.
#tsd/tsd.m looks like this:
function tsa = tsd(t, Data)
% tsd Creates tsd object (tsd = class of timestamped arrays of data)
%
% tsa = tsd(t, Data)
%
% INPUTS:
% t - list of timestamps - must be sequential, but don't have to be continuous
% Data - data, possibly an array. If data is n-dimensional, then time should be the FIRST axis.
% OUTPUTS:
% tsa - a tsd object
%
% Completely compatible with ctsd.
%
% Methods
% tsd/Range - Timestamps used
% tsd/Data - Returns the data component
% tsd/DT - Returns the DT value (mean diff(timestamps))
% tsd/StartTime - First timestamp
% tsd/EndTime - Last timestamp
% tsd/Restrict - Keep data within a certain range
% tsd/CheckTS - Makes sure that a set of tsd & ctsd objects have identical start and end times
% tsd/cat - Concatenate ctsd and tsd objects
% tsd/Mask - Make all non-mask values NaN

if nargin == 0
tsa.t = NaN;
tsa.data = NaN;
tsa = class(tsa, 'tsd');
return
end
if nargin < 2
error('tsd constructor must be called with T, Data');
end
tsa.t = t;
tsa.data = Data;
tsa = class(tsa, 'tsd');
and the Data.m file:
function v = Data(tsa, ix)
% tsd/Data Retrieves data from tsd
%
% d = Data(tsa)
% d = Data(tsa, ix)
%
% INPUTS:
% tsa - tsd object
% ix - alignment list (timestamps)
% OUTPUTS:
% v - the tsa.Data
%
% if called with alignment list, returns those tsa.Data(ix)
% if called without, returns complete tsa.Data

switch nargin
case 2
f = findAlignment(tsa, ix);
v = SelectAlongFirstDimension(tsa.data,f);
case 1
v = tsa.data;
otherwise
error('Unknown number of input arguments');
end
So the script calling the tsd function runs just find in the Matlab session, but the compiler throws the error described above. This is my first time working with Matlab and I am totally stumped. There is another class with a method named "Data", but that shouldn't cause this problem, could it?

Answer 1

I was having the exact same problem and was able to come up with a workaround.
I was facing this problem when I was compiling the MATLAB library using the command
mcc -W cpplib:LibName -T link:lib main.m -a './' -d 'dll_destintaion_dir'
LibName: DLL name
main.m: MATLAB entry point
dll_destintaion_dir: destination where DLL created will be stored
The error was gone when I compiled using this command instead
mcc -W cpplib:LibName -T link:lib main.m -a 'full_path_of_project_folder/*'
-d 'dll_destintaion_dir'
Note: This method does not add folders recursively to the archive. So subfolders have to be added explicitly using another -a flag in the command shown above.
