Re: [omnetpp] Defining own application layer message

Thanks for your help, I have modified my message according to your example, but I still get the following errors:

c:\omnetpp\project\NewApplPkt.msg(1) : error C2470: 'cplusplus' : looks like a f
unction definition, but there is no parameter list; skipping apparent body
c:\omnetpp\project\NewApplPkt.msg(8) : error C2079: 'fragmentList' uses undefine
d class 'noncobject'

c:\omnetpp\project\NewApplLayer.h(14) : error C2955: 'std::list' : use of class
template requires template argument list

I have a list of fragments in my own application layer, I want to broadcast the message including the fragments to other hosts to see if they have the same fragments. Does this keep causing the compiling errors? Please help, thanks!!!

You hace a mistake with the string,

cplusplus {{
#include <string>
#include "ApplPkt_m.h"
typedef std::list<std::string> fragmentList;
}};
