How to build a simple simulink standalone execution file?

First of all i seen the video in on how build the code.

I try build a code myself, so I simply build a simulink model with a source sin wave and output of scope. Then i set the configuration\code generation\system file to rsim.tlc and then i started to build.

I got some error like

Cannot CD to C:\Users\KELVIN~1\AppData\Local\Temp (Name is nonexistent or not a directory). similar to this one I think this is not the real problem, the real problem, the real problem is i think i don't think my procedure it right, or maybe something is missing on the model.

It will be best if you record a video on making a simple exe file. Or can you help me to look on this problem.

Do you observe the same when you: 1. CD to directory like 'c:\work' 2. Save the model to 'c:\work' 3. Build?

If you want to generate standalone C/C++ code from your model, grt.tlc or ert.tlc are more appropriate - what happens when you pick one of them?

Agree with Suneesh. Try to simplify the issue by using a simpler directory structure. There may be an issue somewhere between MATLAB and Windows trying to shorten the directory name (KELVIN~1).

Also agree with Kaustubha, grt.tlc is likely the most appropriate simulation target file if you only want to generate the fastest running EXE from Simulink.

Problem Found: The temporary memory got some problem and was unable to store space anymore.

Create another user and try run it with that user. It works

First of all the directory exist. I try saving my work on that directory, and build. Still not working. 1 weird thing, i can't see any file in that directory in matlab. But i check the folder i saw the mdl file, rsim.tlc folder ...etc for the simple model i build. I reinstall matlab. Still not working. I try on others computer it works fine.

It is a directory problem, but i ain't gonna reformat my computer for one minor problem. I asking how to change the location of generated code and exe file.

sorry for late reply, the system say if anyone reply me they will email me, but i didn't receive any email. My apology

I suspect your TEMP environment variable is set to C:\Users\KELVIN~1\AppData\Local\Temp which Simulink Coder is trying to use. You can verify this either from the Windows Environment Variable window, or from the MATLAB prompt using the command "getenv TEMP". If this is the case, try changing it to a path that exists, restart MATLAB and try again.

PS: I think you get email notifications only if someone posts an answer. All of our notes were comments, not answers, which is probably why you did not get a notification.

Dear Kaustubha Govind,

I have the same problem when I wish to start Simulink or open a Simulink model. I changed my user system variable (TEMP and TMP) multiple times. Everytime it work for some hours and then the exact same error occurs again. It's driving me nuts.

Will you please provide me with a solution?

R2014a, Windows 8.1 64bit

I agree with Shady N. The solution is only temporary. I am having the same issue. I am also using R2014a, Windows 8.1 64bit

Shady, Gentian: You may want to contact Tech Support, so they can do further investigation.

Also, I would recommend setting the environment in the shell (Linux) or System Settings (Windows) - when you use the SETENV command in MATLAB, it only applies to that session of MATLAB.
