[Tinyos-help] CTP data header size

[Nouha Baccour]

Hi,
I added some fields in the ctp_data_header_t and deleted the field etx.
The original size of CTP data header is 8 bytes, but due to added
fields, the size of the CTP data header becomes 9 bytes.

When I compile I have many errors related to the message_t structure, like:

-----------------------------------------------------------------------------------------------------------------------
/opt/tinyos-2.x/tos/types/message.h:14: redefinition of `nx_struct message_t'
/opt/tinyos-2.x/tos/types/message.h:14: warning: tag message_t shadows enclosing

-----------------------------------------------------------------------------------------------------------------------

I think that these errors come from the extra fields in the CTP data
header, Am I right?

If so, how can resolve this problem?

Thanks
