Library compiler and MinGW-w64

Hello,

I'm trying to create my first Excel Add-In, but continue to get an error when compiling with Library Compiler. Many of the tutorial videos make it look so easy, but they don't say anything about getting the software setup properly.

I am using 2019a and installed the MinGW-w64 through the Add-Ons menu/browser. This screenshot confirms that it is installed:

However, I get the following error message from Library compiler:

What am I doing wrong? Is there something else I need to install?

Please show the complete log of it looking for compilers.

Walter, I've attached a PDF document that contains all of the PackagingLog. Please let me know if you would prefer it in some other format. Thanks for taking a look at this.

Try manually doing

mex -setup C
mex -setup C++

Here are the results of executing those commands:

>> mex -setup C

MEX configured to use 'MinGW64 Compiler (C)' for C language compilation.

variables with more than 2^32-1 elements. You will be required

to update your code to utilize the new API.

Okay, those look good. That warning is not at all an error: it is just saying that if you have code that was written for 32 bit days that the code needs to be updated.

Now that you have done that, try doing the build again.

Thanks, Walter. Unfortunately, the Library Compiler still failed, saying that no supported compiler was found.
