I opened a service ticket but I was hoping to get started over the weekend and perhaps someone else has run into this and can help.

I have a workstation running R2013a with group licenses for Matlab, Simulink, Signal Processing, Parallel Computing, and Control System toolboxes.

I received a trial license for Matlab Compiler and Coder today. The installation went fine (based on messages) and the Manage License web page shows the trial license has been activated to my machine ID and is good for a month.

But when I try to start compiler or coder I get:

Error using deploytool (line 34) Error: Failed to checkout a MATLAB Compiler license.

I'd appreciate any suggestions.

Thanks, Joe

在 MATLAB Online 中打开

This seems to be a license issue. Try the following to see if you can even check out the licenses:

[TF errmsg] = license('checkout','compiler')
[TF errmsg] = license('checkout','matlab_coder')

If you see 1 s as output then you should be able to use the tools, if not then you should the error in 'errmsg'. If you are unable to checkout the license, you may have to ask your sys admin or wait till Installation support respond to your service request.

Thank you Shashank.

The command did give an error that it couldn't find the license. Looking at the paths it was a permissions problem. The license files were not world readable.

I have had this umask problem before. I usualy have it set to 027 and most installers will modify it before installing their product (022 is typical).

I caught this and reinstalled the programs as root but evidently the license file was not reset.

Again, thank you for your help.

Joe
