to learn how to use the library compiler, I tried packaging in C language by making a magic square function.

However, the following error is appearing:

According to the error, MinGW was installed through the link, but the same problem is appearing.

Could someone give me a solution?

my matlab version is R2020a

[GUS]

my function code is as follow:

function m = magicsquare(n)

if ischar(n)
    n=str2double(n);
end
m = magic(n)

Hi GUS,

As per my understanding, you are trying to learn how to use the MATLAB library compiler by creating a C shared library.

You can leverage the below documentation for the detailed instructions on how to create a C shared library and troubleshoot compilation failures.

Create a C Shared Library with MATLAB Code: www.mathworks.com/help/compiler_sdk/gs/create-a-c-application-with-matlab-code.html

Troubleshooting Compilation Failures: www.mathworks.com/help/compiler_sdk/cxx/does-the-failure-occur-during-compilation.html

Hope this helps!
