I'm attempting to incorporate an SDK into my project and wanted to use Qt for the gui development. According to SDK documentation: " Our VC++ SDK requires the Visual C++ 2010 Redistributable package from Microsoft and the Code Synthesis XSD compiler and libraries from Code Synthesis." So first i installed XSD(version 3.3) and added the various necessary dependencies in visual studio 10 and successfully built the examples. I then installed the Qt 5.5 plugin(also later installed the Qt5.5_msvc10 build...both lead to the same error).
The problem i keep encountering is that while I get a successful build just using the functions and classes from the SDK, any attempt to do anything with it(access elements of a std::list, for example) produces the following error:
LNK2019: unresolved external symbol "__declspec(dllimport) public: class ATL::CStringT<wchar_t,class StrTraitMFC_DLL<wchar_t,class ATL::ChTraitsCRT<wchar_t> > > __thiscall CAccount::GetAccountId(void)" (__imp_?GetAccountId@CAccount@@QAE?AV?$CStringT@_W V?$StrTraitMFC_DLL@_WV?$ChTraitsCRT@_W@ATL@@@@@ATL @@XZ) referenced in function "private: void __thiscall MainWindow::on_pushButton_2_clicked(void)" (?on_pushButton_2_clicked@MainWindow@@AAEXXZ)
For Example:
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QMainWindow>
#include <QtCore>
#include "ladderwindow.h"
#include "OAuth/OAuthSDK.h"
#include "Accounts/AccountSDK.h"
#include "Market/MarketSDK.h"
#include "Order/OrderSDK.h"
#include <QtNetwork>
namespace Ui {
class MainWindow;
}
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();
private slots:
void on_pushButton_2_clicked();
private:
CAccountSDK *acc;
AccountList alist;
};
#endif // MAINWINDOW_H
//Mainwindow.cpp//
#include "mainwindow.h"
#include "ladderwindow.h"
#include "ui_mainwindow.h"
#include <QCoreApplication>
#include <QString>
#include <OAuth/OAuthSDK.h>
#include <Accounts/AccountSDK.h>
#include <Market/MarketSDK.h>
#include <Order/OrderSDK.h>
#include <QUrl>
#include <QUrlQuery>
#include <QWebElement>
#include <QDebug>
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{...}
void MainWindow::on_pushButton_2_clicked()
{
try {
AuthCode = ui->lineEdit->text();
mAuth->GetAccessToken(*client,AuthCode.toStdString());
try {
acc = new CAccountSDK(*client);
alist = acc->GetAccountList(); //Builds, application output window streams a XML of the response
std::wstring mangledstringtest(CString("WTF"));
ui->textBrowser->append(QString::fromStdWString(mangledstringtest)) ;
// This and all other attempts to do anything with alist fails to compile
foreach(CAccount i, alist)
{
//ui->textBrowser->append(QString::fromStdString(i.GetAccountId()));
//USES_CONVERSION
ui->textBrowser->append(QString::fromWCharArray((i.GetAccountId().G etBuffer())));
//std::wstring mangledstring(CString(i.GetAccountId()));
//ui->textBrowser->append(QString::fromStdWString(mangledstring));
}
} catch (...) {}
ladder = new ladderwindow(this);
ladder->show();
}
catch (...) {}
}
Since the calls I make are from the libraries from the SDK, my thought is that perhaps a) i haven't properly specified the paths to the necessary dlls from the codesynthesis xsd installation or b) i need to make some modifications and/or includes of various string related header files included with the SDK.

I've tried switching around the order in which ive added the various Libraries as well changing between static and dynamic with no luck. Ive searched and tried a whole bunch of different means of intermediate conversions to see if i could convert the cstring into something i could then convert to a Qstring but anything i've tried still produces the linker error.
