Hi Alexander,

According to the email you sent me, you have checked out Kranc using an Einstein Toolkit thornlist from the branch ET_2010_06.  In the version of Kranc for that branch, the GenericFD_GetBoundaryWidth function did not yet exist.  Now, for some reason, you have a version of WeylScal4 which has been generated with a newer version of Kranc and uses this function.  Did you check out WeylScal4 from the same thornlist?  Can you post the section of the thornlist which refers to WeylScal4?
