Unrecognized function or variable 'gcp' in compiled stand alone application

3 views (last 30 days)
Compiling via mcc i get the following error at runtime (m2022a).
Is there a specific options or compile directive to ensure the paralell toolbox is included in the standalone application?
Unrecognized function or variable 'gcp'.
Error in MatlabThreads.Helper.StartThreadPool (line 28)
'gcp' may have been excluded from the MATLAB search path at compilation due to misuse of the path related mcc flags (-N, -p, -I).
Have the application owner verify that these flags were correctly used.
Contact the application owner for more details.

Notice that the documentation for gcp does not have any Extended Capabilities section. It might not be available in compiled executables.
Instead record the output of the call that creates the pool and use that variable.

Well if a persistent or global variable is not acceptable then I guess your next option would be to reimplement in a different programming language.

I would not expect you to need a specific flag to include gcp. I put together a super simple code example:
parfor i=1:10
and compiled it with:
mcc -m SimpleThreadPoolCompiler.m
When I run it from the command prompt, it works without issue. If you compile this simple example and attempt to run it, do you hit the same error?
