How can I install MinGW for use in a new version of MATLAB?

Hello,

I want to ask some help for installing a C-language complier 'Mingw-w64', it has installed on a Matlab 2019b and work pretty well.

However, i moved to 2021a recently since a konw bug on matlab (the 'invoke' code for instrument control). the compiler was firstly installed automaticly for first time matlab launch. Then when I compile my previous code, it asked to instal the compiler that is shown installed in adds-on.

when I type 'mex -setup -v' in command window, it shows a 'Yes' for environement variable and a 'No' for the 'gcc.exe'. Thus i unstalled the compiler in addson and i wanted to reinstal the complier. However, this time download of the software is blocked.

Any one suffered a similar issue?

Are you using the Add-Ons explorer to install/uninstall?

It installs the MinGW compiler from the file exchange.

[K Hu]

Yes, all the installations were via the Add-Ons explorer for both 2019a and 2021a. The 2021a asked to update the packages at the first launch, and I saw all the add-ons of 2019a on the list. Besides other packages, only the 'Mingw-w64' can not be installed. I tried three different times, and it never worked.

Go to the Add-Ons explorer and type mingw64. Then, proceed with downloading and installing the compiler.

I hope this picture can better explain my problem, and I think we used to use add-ons manager to install toolbox and hardware drives.

As shown in the picture, the compiler cannot be installed in Matlab 2021a in the same environment configuration that the 2019b had installed three months ago.

Please try and click the link "MATLAN Answer" that shows in the Error message.

Hi, i had tried the solution mentioned in the forum and i got the install log file. Which shows that the problem is due to internet connection.

I want to ask to sent me the package to install the minGW-W64, since I can not desactivate the anti-virus program.

Regards,

Kejun
