MATLAB: Error after compiling figure as exe, but running figure causes no problems

Question

Hi.

I have created a figure in GUIDE and tested it multiple times. It works fine. However, when I use deploytool to compile an executable and I run the .exe file, I get the error message "DATENUM failed. Error in => ImportTool.m at line 42"

I have checked the ImportTool.m function. There is no datenum in line 42.

This is the initialization code:

gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @ImportTool_OpeningFcn, ...
                   'gui_OutputFcn',  @ImportTool_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);
if nargin && ischar(varargin{1})
    gui_State.gui_Callback = str2func(varargin{1});
end
if nargout
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
    gui_mainfcn(gui_State, varargin{:});
end

Line 42 is the following:

gui_mainfcn(gui_State, varargin{:});

before the last else

Any idea what could be the problem? I guess gui_mainfcn() uses datenum and for some reason it failed… I will check again, but I am pretty sure I have not left out any of the necessary functions.

Answer 1

Okay, I found the problem. I included a function "TimeZoneConvert.m" which seems to use toolbox functions that cannot be deployed.
