Can't read directory [ec:path]: [ec:OS error message]
Electric Make encountered an error while trying to get the contents of the directory identified in the error message. The specific cause of the failure is given by the OS error message.
Because the error involves an external system in this context (the filesystem on the eMake host), the list of possible causes for this error is virtually limitless: a corrupted filesystem; hardware failure; insufficient permissions; etc. Refer to the specific OS error message to determine the cause of the failure.
The fix depends on the cause of the error.
