No implementation for 'FromWorkspace' has been defined in 'C:\Program Files\MATL​AB\R2017b\​rtw\c\tlc\​mw\genmap.​tlc'.

When compiling my model with the Simulink Coder using the grt.tlc target I keep getting this error message: No implementation for 'FromWorkspace' has been defined in 'C:\Program Files\MATLAB\R2017b\rtw\c\tlc\mw\genmap.tlc'. Any advice on how to troubleshoot this?

Hi Sebastian,

thank you for the suggestion. Yes, I got in contact with Matlab support and after a little back and forth I could solve the problem doing exactly what's described in the link.
