a set of scruct

[theStorx]

hi everybody,
i'm new of c++ programming.
i'd like to create a set of object defined throw a struct.

i wrote this:

typedef std::set<terminal,std::less<Address> > setUser; //added by giuseppe 

struct terminal{
	Ptr <Node> ptrN;
	Ptr <LteNetDevice> ptrLND;
	Ptr <UeNetDevice> ptrUND;
	double lifeTime;
	Address macUe;
};

by i get the followed error:
terminal was not declared in this scope
invalid type in declaration before ';' token
template argument 1 is invalid
template argument 3 in invalid


please help me to solve this mistake.
thank you very much

Put the typedef after the struct definition.

it doesn't work also with typedef :(

¿same error?
Everything needs to be defined before you use it. I assume that you do included the definitions of set, less, Address, etc.

Provide a minimal example.

i changed a bit my code but it doesn't work as well

#include <set>
#include <algorithm>
#include <iterator>
 
typedef std::set<ueterm,std::less<Address> > setUser; //added by giuseppe 

typedef struct terminal{
	double lifeTime;
	Mac48Address macUe;
}ueterm;

the error are

Description	Resource	Path	Location	Type
‘ueterm’ was not declared in this scope	MioScenario.cc	/SpectrumSharing/scratch	line 39	C/C++ Problem
invalid type in declaration before ‘;’ token	MioScenario.cc	/SpectrumSharing/scratch	line 39	C/C++ Problem
template argument 1 is invalid	MioScenario.cc	/SpectrumSharing/scratch	line 39	C/C++ Problem
template argument 3 is invalid	MioScenario.cc	/SpectrumSharing/scratch	line 39	C/C++ Problem

¿What's Address?
As I told you the first time

#include <set>
#include <algorithm>
#include <iterator>
 
typedef struct terminal{
	double lifeTime;
	Mac48Address macUe;  //¿where's Mac48Address definition?
}ueterm;

typedef std::set<ueterm,std::less<Address> > setUser; //Put the typedef after the struct definition.   

[theStorx]

sorry ne555

it should be like that

#include <set>
#include <algorithm>
#include <iterator>
 
typedef struct terminal{
	double lifeTime;
	Mac48Address macUe;  //¿where's Mac48Address definition?
}ueterm;

typedef std::set<ueterm,std::less<Mac48Address> > setUser; //Put the typedef after the struct definition.
