S-Function builder fails compilation diagnostics gives "Error using fopen ..."
显示 更早的评论
I followed the very simple and straightforward guide to write an S Function Builder Block here https://www.mathworks.com/matlabcentral/mlc-downloads/downloads/submissions/39354/versions/10/download/zip/DriversGuide.zip and I get the following error when clicking the Build button:
Error using fopen
The file name contains characters that are not contained in the filesystem encoding.
Certain operations may not work as expected.
I have r2018a.

What is the name you are giving to the S function?

I looked through the various models in the .zip but I could not see anything obvious.
Which model was it that you had open when you did the build ?

This is also occurring on my system when trying to build from the built in MATLAB s function builder example model.
open_system([docroot,'/toolbox/simulink/sfg/examples/sfbuilder_example']);
This only started happening after upgrading to r2018a.

This problem does not occur when the exact same thing is tried back on r2017b.

@Mathworks, is this a bug in R2018A, that S-Function Builder does not work?
