function [ret_createCTFFunctionbyMPSLib] = createCTFFunctionByMPSLib(mFile)
% % to create a ctf service that takes a mfile and convert to a ctf
% if exist(mFile, 'file') ~= 2
if ~exist('mFile', 'var') || isempty('mFile')

% Define the name of the output CTF
% archiveName = 'GeneratedCTF'; % Changed to GeneratedCTF
% Define the path to the function to be included
% functionFiles = 'mymagic.m'; % Add all required function files here

On the user guide, it mentioned that we can use compiler.build.productionServerArchive to create ctf prgrammatically. However, I found out I would get the following warning if I start put options to this class. And here is the warning: "C:\Program Files\MATLAB\R2024a\toolbox\compiler_sdk\cli\build\+compiler\+build\ProductionServerArchiveOptions.m", "mps.internal.validateFunctionSignatures" are excluded from packaging for the MATLAB Runtime environment according to the MATLAB Compiler license.
Are the guide conflicts with what are allowed?

Hi @Biyan Li,
I believe that you are getting the warning:
"mps.internal.validateFunctionSignatures" are excluded from packaging for the MATLAB Runtime environment
according to the MATLAB Compiler license
is most probably because, the 'validateFunctionSignaturesJSON' does not support validating in MATLAB Production Server. You can learn more about this warning from the following MATLAB documentation:
https://www.mathworks.com/help/mps/restfuljson/matlab-function-signatures-in-json.html
While I deployed the script to MPS using deployed archive, I was getting the following warning:
"compiler.build.productionServerArchive" are excluded from packaging for the MATLAB Runtime environment
according to the MATLAB Compiler license. Either remove the file or function from your code, or use the
MATLAB function "isdeployed" to ensure the function is not invoked in the deployed component.
This basically means that ‘productionServerArchive’ function is not supported by MATLAB compiler. To resolve this, any function that is not supported by MATLAB Compiler should be used within "isdeployed" function. This ensures that the non-supported functions are only called when not running in deployed mode. You can reframe your script as follows:
if ~isdeployed
<function that is not supported by MATLAB compiler>
end
Leverage the following MATLAB documentations to understand more about the "isdeployed" function:
https://www.mathworks.com/help/compiler/isdeployed.html
You can also refer the following MATLAB documentation to understand what all functions are not supported by MATLAB compiler:
https://www.mathworks.com/help/compiler/unsupported-functions.html
Hope this helps!
