Im compiling this code for wireless network gaming, but after i run 'make' i get this error

Quote:node-common/ll-arp.o node-common/ll-arp.cc
./80211/net-interface-80211.h:59: error: invalid use of undefined type ‘struct NetInterface’
node-common/ll-arp.h:49: error: forward declaration of ‘struct NetInterface’
./80211/net-interface-80211.h:107: error: invalid use of undefined type ‘struct NetInterfaceConstructor’
./node-common/net-node.h:52: error: forward declaration of ‘struct NetInterfaceConstructor’

the class called in net-interface-80211.h is

Quote:class NetInterface80211 : public NetInterface {
public:
virtual ~NetInterface80211 ();

int getBSSID (void);

what should i do?

thank you

You need to #include the header that defines NetInterface. If it's in the same file, you need to make sure it appears before you declare NetInterface80211.
