Simscope Custom component in Library

I am constantly getting an error : >>ssc_build Generating Simulink library 'customblockLib_lib' in the MATLAB package parent directory '\\bfhfilerbe01.bfh.ch\kan1\MATLAB' ... Failed to generate 'customblockLib_lib'

Caused by: Undefined function 'validate' for input arguments of type 'double'.*__*** Please note I am trying to build the library component at the pakage lib with + sign in the beginning. I can not attach the file as it is with .ssc extension.

Could you please help me to understand the error here. I guess I have used pretty simple script. I appreciate your time.

This is an old question, but I got this error when I had a Simulink project *.slx file with the same name as a simscape block *.ssc that I was trying to build in the same folder.

You can attach the .ssc file if you put it inside a ZIP.
