I have created a GUI in MATLAB that has callback functions defined in other files. For example, I could have a pushbutton whose 'Callback' property is set equal to:

myguicallback;

where MYGUICALLBACK is an M-function I have written. This GUI operates successfully in MATLAB, but when I try compiling it, I receive the following error:

 ??? Unable to locate myguicall; as a function on the MATLAB path 
 Warning: An object instance still exists. 
 Use the objectdirectory command to see a count of existing instances. 
 Depfun error: 'Unable to locate myguicall; as a function on the MATLAB path' 
 ??? Error executing mcc, return status = 1.

This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:

We have verified that there is a bug in MATLAB Compiler 4.1 (R14SP1) in the way that GUIs are compiled.

To work around this issue, remove the semi-colon from the end of all callback function declarations. For example, modify the 'Callback' property of a pushbutton from:

myguicallback;

to:

myguicallback

Additionally, the callback may be specified in a FIG-file. You may inspect the contents of a FIG-file using HGLOAD to open the file and FINDALL to inspect the children.

After you perform this modification for all callback function declarations, the depfun error should not be encountered.
