MATLAB: Does the STF_make_rtw_hook method work with accelerator mode

acceleratorsimulink coder

I'm trying to customise my build process with the STF_make_rtw_hook File mechanism.

https://uk.mathworks.com/help/ecoder/ug/customizing-the-target-build-process-with-the-stf-make-rtw-hook-file.html

It was my belief that accelerated models would use the 'accel.tlc' STF and therefore I should be able to provide an accel_make_rtw_hook.m file – however this does not seem to work.

Is what I'm trying to do not possible or should I assume there is a problem with my implementation?

I eventually managed to get this to work by creating a modelrefsim_make_rtw_hook.m file instead so it seems the answer is yes.

Which operating system are you using? If you are using Windows 95, Windows 98, or Windows ME then the program is command.com instead of cmd.exe

You might need to use

mbuild -setup

but I have not figured out yet when that is needed or not.

MATLAB: How to send custom input arguments from ‘rtwbuild’ function to a hook file (STF_make_rtw_hook)

The ability to use custom input arguments in the 'rtwbuild' function is not available in R2019b. However, as a workaround you can use an environment variable or another persistent state that can control the behaviour inside the STF_make_rtw_hook file. For example:

>> setenv('UseMyFileDiffTool','1');

Then, in your STF_make_rtw_hook file, you can query the environment variable using the 'getenv' function to check if it's set to '1' or '0' and therefore execute your hook file accordingly.

Another possible workaround would be to add a custom option to the target called 'UseMyFileDiffTool' that would be settable on the model. You can refer to the following documentation page regarding this workflow:

See section on 'Define and Display Custom Target Options':

https://www.mathworks.com/help/rtw/ug/customizing-system-target-files.html

You can then set this option on your script or Command Window programmatically before calling the 'rtwbuild' function.
