Unable to determine MEX compiler: use mex -setup to configure your system.

Hi,

I got this error while I'm generating my code at MATLAB Coder.

Any idea on how to resolve it? I couldn't find any solution available..

Thank you.

What happened when you used

mex -setup

Which MATLAB release are you using (including update number)? What compiler do you have installed at the moment?

Hi,

I'm using R2019b currently.

How can I know which compiler am I using?

Hi,

When I try to generate the code, the error shown as below.

However, when I try to click on the "mex-setup" wording in blue, it doesn't allow me to do so.

[Walter Roberson]

Go to the MATLAB command line and give the command

mex -setup -v

Hi,

It is working now, thank you very much!
