Description
You may receive 'Severe' errors while using the Nios® II Software Build Tools if you have version 6.1 installed on your machine and are using a later version. This is due to the librarian finding files from version 6.1 which causes a parse error in later versions.
Workaround:
Uninstall version 6.1 or remove references to version 6.1 from your SOPC_BUILDER_PATH so the librarian does not find the older files.
