Error in ns2.28 when trying to exchange information between two layers
 

Hi all,

I'm working on IEEE802.11e EDCA in ns2.28 and my cross layer is between the udp class (udp.cc) and the Mac802_11e class (mac-802_11e.cc). I follow all the instructions in this link (http://wmnatupdiliman.blogspot.com/2...16500257750)in order to exchange information between these two layers but I got an error when I include in the udp.h header file the mac-802_11e.h file which is :

In file included from apps/udp.h:27,
from apps/udp.cc:24:
./mac/802_11e/mac-802_11e.h: At global scope:

./mac/802_11e/mac-802_11e.h:304: error: ‘Mac’ has not been declared
make: *** [apps/udp.o] Error 1


and this error belongs to #include "mac/mac-802_11e.h" line in the udp.h file,
So if someone has an idea about how to fix this error, please help me ? Also when I tried to include the ns2.28 integrated mac layer (mac-802_11.h)in the udp class, I got the same error. I'm stuck in this error from long time.

Thanks for your help in advance.
