Why do I get the error message "wrong # args: should be "cd ?dirName?"" while using SOPC Builder version 9.0?

Description

You may encounter the following error message while adding a custom component containing callbacks to your system in SOPC Builder version 9.0:

wrong # args: should be "cd ?dirName?"

This message is a result of the project directory name containing spaces or special characters that are not supported by SOPC Builder.

To resolve this issue, remove any spaces or special characters, other then underscores, from the project directory name. For example, if your directory is named 'my project', rename it to 'my_project'.
