"Variable" was not declared in this scope - c++

Question

I am getting this error when I try to compile my class. I have made sure there is function prototypes and variables are initilized correctly, hopefully someone can help me figure out the problem

g++ -c View.cc
g++ -c AcctList.cc

Makefile:31: recipe for target 'Transaction.o' failed

Here is my header file
#ifndef TRANSACTION_H
#define TRANSACTION_H
#include <string>
using namespace std;
#include "defs.h"
class Transaction
{
public:
Transaction(TransType = TTERROR, TransState = TSERROR,int = 0 ,float = 0);
int getTransID();
TransType getTType();
TransState getTState();
string getDate();
int getTAcctNum();
void setDate(string);
float getAmount();
private:
static int nextTransID;
int transID;
TransType tType;
TransState tState;
string date;
int tAcctNum;
float tAmount;
};
#endif
Here is my source file
#include "Transaction.h"
#include "defs.h"
#include <string>
using namespace std;
int Transaction::nextTransID = 2001;
Transaction::Transaction(TransType t, TransState s, int acct, float amount)
{
transID = nextTransID++;
tType = t;
tState = s;
tAcctNum = acct;
tAmount = amount;
}
int getTransID() { return transID; }
TransType getTType() { return tType; }
TransState getTState() { return tState; }
string getDate() { return date; }
int getTAcctNum() { return tAcctNum; }
float getTAmount() { return tAmount; }
void setDate(string d)
{
date = d;
}
I am kinda lost on what is the issue

Answer 1

This:
int getTransID() { return transID; }
has nothing to do with your class, it's a global function.
You meant:
int Transaction::getTransID() { return transID; }
Also, that function (and the other getters) should be made const to signal that they don't modify the object.
