MATLAB Compiler getting stuck during build process

Question

I built a GUI in MATLAB that makes use of the Instrument Control Toolbox, among other things. I tried to compile this GUI with deploytool but it's getting stuck during the compile:

ant:

<mkdir dir="Z:\My Path\MyApp\distrib" />
<mkdir dir="Z:\My Path\MyApp\src" />
mcc -o MyApp -W WinMain:MyApp -T link:exe -d 'Z:\My Path\MyApp\src' -N -p instrument -w enable:specified_file_mismatch -w enable:repeated_file -w enable:switch_ignored -w enable:missing_lib_sentinel -w enable:demo_license -v 'Z:\My Path\MyApp.m'

Compiler version: 4.18.1 (R2013a)   
Processing C:\Program Files\MATLAB\R2013a\toolbox\matlab\mcc.enc
Processing C:\Program Files\MATLAB\R2013a\toolbox\instrument\mcc.enc
Processing C:\Program Files\MATLAB\R2013a\toolbox\shared\instrument\mcc.enc
Processing include files...
2 item(s) added.
Processing directories installed with MCR...
The file Z:\My Path\MyApp\src\mccExcludedFiles.log contains a list of functions excluded from the CTF archive.
0 item(s) added.
Generating MATLAB path for the compiled application...
Created 54 path items.

And that's all she wrote. Of note, the final statement of "Created 54 path items" to me doesn't make a whole lot of sense, since I don't have 54 dependencies.

I changed the path that the code is on to Z:\My Path\MyApp to be generic. It may or may not be important but there are spaces in the path. I mentioned this because maybe that's my problem. Z:\ is a network drive instead of a local drive. Some dependencies live on R:\, which is also a network drive. All dependencies are on the MATLAB path or in my local folder.

I'm using MATLAB R2013a x64 and the Windows SDK 7.1 (used mbuild -setup to set this).

The deploytool and MATLAB are both responsive - I can cancel the build process with no problem. I ran the mcc code verbatim as above and it's still stuck in the same place with no indication that it's working. Hitting CTRL-C to interrupt it gives no error messages or anything.

Does anyone know what's going on? It must be something to do with the mcc call, I'm sure of it.

Answer 1

It looks like this problem is due to my license file being located on a network server rather than locally. Working with MathWorks tech support really helped out here.

When using mcc, specify a local license file with the -Y flag. The compile then goes from 20 minutes or so to about 2. An example call:

mcc -m -v -N -Y alpha.lic myApp.m
