Unable to pass reference from one class to another - c++

Question

I'm writing a C++ program intended to manage the resources and duties in a flat.
This program is intended to run in Linux Shell.
I created a class call HomePage for users to login. I've also got another class called SelectionPage. Which are the Menus after the user got past the login. In my main functions, i wish to pass some data obtained by an instance of the HomePage class, to an instance of the SelectionPage class.
I've been stuck here for at least 6 hours, Could someone please help?
Here's the error message:
g++ C_Main.cpp C_HomePage.cpp C_SelectionPage.cpp -o Project
C_Main.cpp: In function ‘int main()’:
C_Main.cpp:17:93: error: no match for call to ‘(std::vector<std::basic_string<char> >) ()’
C_Main.cpp:17:122: error: no match for call to ‘(std::vector<std::basic_string<char> >) ()’

C_HomePage.cpp:294:44: error: no ‘std::vector<std::basic_string<char> > HomePage::getResourcesList()’ member function declared in class ‘HomePage’
C_SelectionPage.cpp:9:144: error: declaration of ‘SelectionPage::SelectionPage(std::string, int, std::vector<std::basic_string<char> >, std::vector<std::basic_string<char> >, std::string)’ outside of class is not definition
C_SelectionPage.cpp:9:146: error: expected unqualified-id before ‘{’ token
make: *** [Project] Error 1
Here is my main()
// Testing Home Page Functionality
#include "H_HomePage.h"
#include "H_SelectionPage.h"
using namespace std;
string initializationFile = "D_initialization.dat";
string flatMemberFile = "D_flatMember.dat";
int main()
{
HomePage frontEnd(initializationFile); //Create Boundary Object
system("clear"); //Clear Terminal Screen
frontEnd.login(flatMemberFile);
SelectionPage Menu(frontEnd.getManager(), frontEnd.getInitPoints(), frontEnd.getDutiesList(), frontEnd.getResourcesList(), frontEnd.getLoginName());
Menu.showManagerMenu();
return 0;
}
Here's my constructor for SelectionPage class, as described in the header file:
...
SelectionPage(string Manager, int Points, vector <string> dutiesList, vector <string> resourceList, string loginName);
...
Here's the implementation of the constructor for SelectionPage class:
SelectionPage::SelectionPage(string newanager, int points, vector <string> newDutiesList, vector <string> newResourceList, string newLoginName);{
manager = newManage;
initPoints = points;
dutiesList = newDutiesList;
resourceList = newResourceList;
loginName = newLoginName;
}
could someone please, please help? I'll be ever so grateful!

Look at your error messages carefully.
C_HomePage.cpp:290:41: error: no ‘std::vector<std::basic_string<char> > HomePage::getDutiesList()’ member function declared in class ‘HomePage’
C_HomePage.cpp:294:44: error: no ‘std::vector<std::basic_string<char> > HomePage::getResourcesList()’ member function declared in class ‘HomePage’
You probably have incorrect declarations for HomePage::getDutiesList() and HomePage::getResourcesList(), or none at all. It's hard to tell what exactly is wrong with them without looking at the class declaration. This is also the reason of compiler errors in your main().
The reason of the other two compiler errors is probably the spurious ; between ) and {' in the definition ofSelectionPage::SelectionPage`. Get rid of it.
