I am a bit stuck at the moment with a little sample project that I would like to run to test some cryptology that I want to use in a main project.
Basically I am using the latest Qt Creator and I have created a simple window dialog. Furthermore, I would like to test the PBKDF2 implementation through CkCrypt2
So what I have done is downloading the X64 version of the library and added it to my project folder. I then told my Qt project to use an external library, the final .pro file looks like this:
#-------------------------------------------------
#
# Project created by QtCreator 2013-06-09T18:09:44
#
#-------------------------------------------------
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = crypt2test
TEMPLATE = app
SOURCES += main.cpp\
m
ainwindow.cpp
HEADERS += mainwindow.h
FORMS += mainwindow.ui
win32:CONFIG(release, debug|release): LIBS += -L$$PWD/libs/ -lChilkatDbgDll_x64
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/libs/ -lChilkatDbgDll_x64d
else:unix: LIBS += -L$$PWD/libs/ -lChilkatDbgDll_x64
INCLUDEPATH += $$PWD/include
DEPENDPATH += $$PWD/include
I can successfully load the library but I cannot start the application.
My mainwindow.cpp looks like this:
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include "CkCrypt2.h"
#include <QDebug>
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
CkCrypt2 crypt;
bool success;
success = crypt.UnlockComponent("Just some random text ");
if ( !success )
{
qDebug() << "Not successfully unlocking the library";
}
}
MainWindow::~MainWindow()
{
delete ui;
}
The error message I get in the compiler is:
c:\qt\qt5.0.2\tools\qtcreator\bin\crypt2test\include\CkString.h:127: error: C2061: syntax error : identifier 'SYSTEMTIME'
c:\qt\qt5.0.2\tools\qtcreator\bin\crypt2test\include\CkString.h:129: error: C2061: syntax error : identifier 'SYSTEMTIME'
C:\Qt\Qt5.0.2\Tools\QtCreator\bin\crypt2test\include\CkCrypt2.h:429: error: C2061: syntax error : identifier 'SYSTEMTIME'
Looking into the files I see:
void appendDateRfc822(SYSTEMTIME &sysTime);
void appendDateRfc822Gmt(SYSTEMTIME &sysTime);
// GETSIGNATURESIGNINGTIME_BEGIN
bool GetSignatureSigningTime(int index, SYSTEMTIME &outSysTime);
// GETSIGNATURESIGNINGTIME_END
Okay, so it is complaining about the SYSTEMTIME construct. So I look up the error C2061
Basically it says:
The compiler found an identifier where it wasn't expected. Make sure
that identifier is declared before you use it.
Which makes sense, so I look up the SYSTEMTIME and try to do :
#include <windows.h>
But that leads to many more errors in the windows.h file itself.
I use the MS Visual C++ compiler in Qt. Even though I use qmake. I am very new to this and I do not understand it all yet. Furthermore, I have no idea how to fix this, because including the windows.h does not help.
What seems to be the problem here ? Is this an issue regarding my compiler or the constulation that I use a third party app which library is compiled with MS Visual C++ and I am now trying to use this on my Windows machine in Qt with a Windows Visual C++ compiler ?
For any help I am gratefully thankful!
EDIT1:
Actually, after a clean all and qmake and build project I have now different errors and none were found in the Windows.h as previously stated. Since there were so many I have made a screenshot: http://i.imgur.com/B8EoENB.png
EDIT2:
I have adjusted the library that I include. Before this I was using the multi-threaded library of CkCrypt in the Debug mode. I have now included the single realease library. Which is located in the same directory.
When including windows.h I got the errors that things were already defined. So I removed the line again. With this result: http://i.imgur.com/z415txR.png
This shows at the bottom that MSVCRT conflichts with other library. It mentions to use NODEFAULTLIB:library but I am not to sure how to do that. Will google and keep this up to date as I process.
