Generated code from Simulink has class definition final

How can I get rid of final within:

// Class declaration for model XXX

class XXX final

{

// public data and function members

public:

code generaded header file?

Hi Thomas,

I understand you are facing an issue with the “final” specifier during code generation in Simulink.

I have faced a similar issue earlier. I did not find any option to remove the “final” specifier in Code generation settings. As a workaround, I have manually deleted this "specifier" from the generated code. You can also make use of post code generation commands to automate that process.

To automate the process of removing the specifier, create a MATLAB function that reads the generated C++ files, searches for the final keyword, removes it, and saves the file.

function removeFinalSpec(buildInfo) 
% Get the list of generated files 
headerFiles = getIncludeFiles(buildInfo, true, true); 

for i = 1:length(headerFiles) 
    file = headerFiles {i}; 
    fileContent = fileread(fileName); 
    regexprep(fileContent, 'final', ''); 
    
    fid = fopen(file, 'w'); 
    fwrite(fid, updatedContent); 
    fclose(fid); 
end 
end 

Using “PostCodeGenCommand” define a post code generation command, which gets evaluated after generating and writing the code to disk and before generating a makefile.

set_param(model, 'PostCodeGenCommand', 'removeFinalSpec(buildInfo)');

To learn more about customizing after code generation, please go through this following official MATLAB documentation.

Thanks

Hope this helps
