As the thread title indicates, when I attempt to generate an audio plugin (after running mex -setup to configure MEX to use visual studio c++ 2019 and validateAudioPlugin) this appears on the console:
>> mex -setup
MEX configured to use 'Microsoft Visual C++ 2019 (C)' for C language compilation.
To choose a different language, select one from the following:
mex -setup C++
mex -setup FORTRAN
MEX configured to use 'Microsoft Visual C++ 2019' for C++ language compilation.
>> validateAudioPlugin('TremoloProj6')
Checking plugin class 'TremoloProj6'... passed.
Generating testbench file 'testbench_TremoloProj6.m'... done.
Running testbench... passed.
Generating mex file 'testbench_TremoloProj6_mex.mexw64'... done.
Running mex testbench... passed.
Deleting testbench.
Ready to generate audio plugin.
>> generateAudioPlugin('TremoloProj6')
..Warning: Selected C compiler is incompatible with C99 (ISO) language standard. Code generation will switch to C89/90 (ANSI) instead. Consider changing C compiler or
target language setting to suppress this warning.
??? The specified code generation target is configured to generate C++, but the C-only compiler, LCC, is the default compiler. To allow code generation, you can
deselect the 'Generate makefile' option. Or, to specify a C++ compiler, enter 'mex -setup' at the command prompt. To generate C code, set the target language to C in
the configuration object.
Code generation failed: View Error Report
I've been searching for information on how to change the target language, but I have not been able to find anything that works when I use it.
Here's the code for the audio plugin I'm trying to generate:
classdef TremoloProj6 < audioPlugin
methods
function out = process(~,in)
out = in;
end
end
end

I figured it out, I needed to use these two lines of code to set the target language to c++:
cfg = coder.config('lib');
cfg.TargetLang = 'C++';
This thread can be closed.

If I recall correctly, using that command made Matlab use Microsoft Visual C++ 2019 for C++ compilation, but Matlab still had the target language for compilation set to C, so it defaulted to the LCC compiler.

I am having the same issue that you had, but your solution is not working. What else can you remember doing?
