I am a newbie building stuffs on Visual Studio and now I am facing this little problem that I am not able to solve. I correctly installed Qt and used the correct paths on the "VC++ Directories" property of my project (indeed in my code the include are correctly seen). The next step should be to put the correct stuffs in the "linker" of my project.. this is at least what I think the problem consists on. Anyway, I have 100 error of this kind:

I know that the problem is stupid but I would like to understand it.. in such a way to learn how to solve it the next time I am going to face it. Thanks in advance!

I am trying to build and compile a Qt project from a repo. The project contains a CMake file, which I am using to build and then compile using nmake. However, I am getting a bunch of linker errors towards the end of the compile and don't have much experience with CMake so not really sure where I am going wrong. I am using MSVC 14.11.25503.
The CMakeList.txt is here:

I am deleting my build folder before running CMake so from what I understand globbing shouldn't be a problem. Here is a part of the output from nmake (I can't fit it all in and at a point it becomes redundant):

This link work for me
https://github.com/KDAB/GammaRay/issues/213
I'm trying to use libtins to parse some DNS answers but I'm getting a lot of linker errors. I added the library and the additional library directories and in the documentation I saw this line
If you are using a static build of libtins on Windows, then you have link your application with tins.lib. You also need to add this macro definition to your project:
TINS_STATIC
This will make your project use libtins without trying to import symbols from a DLL but from the static library.
So I added /DTINS_STATIC to my compiler command line.
But I'm getting this error log

You are linking objects compiled by different versions of the compiler. Try editing Platform Toolset in project properties.
I want to make a plugin for a software. In order to make the plugin, I should make a .dll file but I have faced many challenges about making it. My system is Windows 7 and I'm using Microsoft Visual Studio 2010 as an IDE. I made a dll project and made two source files, one header file and then I built the solution but I encountered the following errors.
Note : before building the solution, I added the path of include and lib directories of the software.

How can I solve these errors ?
In addition to adding the library path to the project setting be sure you also add the required library files(.lib) as an additional dependency for the linker. you can find the additional dependency input field at project->properties->linker->Input and add the actual names(with extension) of the library files separated by a space.
basically the goal of the code is to open a dialog that contain a QWebView (with some content) after a botton is clicked
these is what i did:
mainwindow.h:
class MainWindow : public QMainWindow, public Ui::MainWindowUi
{
...
private slots:
void on_ViewDatabase_clicked();
...
}
mainwindow.cpp:
#include "mainwindow.h"
#include "onlinedb.h"
void MainWindow::on_ViewDatabase_clicked()
{
OnlineDB dlg(this);
dlg.exec();
}
onlinedb.h:
#ifndef OnlineDB_H
#define OnlineDB_H
#include "ui_onlinedb.h"
#include <QDialog>
class MainWindow;
class OnlineDB : public QDialog, public Ui::OnlineDB
{
Q_OBJECT
public:
OnlineDB(LkMainWindow *parent);
~OnlineDB();
private:
MainWindow *MainWindow;
};
#endif
onlinedb.cpp:
#include "onlinedb.h"
#include "mainwindow.h"
///////////////////////////////////////////////////////////////////////////////
//
// OnlineDB class constructor
//
// Create a OnlineDB
//
OnlineDB::OnlineDB(MainWindow *parent) : QDialog(parent), MainWindow(parent)
{
setupUi(this);
QUrl url("http://google.com"); //whatever
webView->load(url);
}
///////////////////////////////////////////////////////////////////////////////
//
// OnlineDB class destructor
//
// Clean up the OnlineDB
//
OnlineDB::~OnlineDB()
{
}
I got several linking errors
Plz can someone help on that?

You have not linked against all the necessary Qt libraries. QWebView is in the QtWebKit library.
I recently installed VS2010 Ultimate. I'm trying to create a MFC dialog based program. I use the built in template, take all the default options, and then compile the project. I then get the following link errors.

I've tried reinstalling VS2010 and made sure I had C++ installed, but I still get the errors. I've tried making the Multiple document and Single document types, these both work. So it's only the Dialog based one that has errors.
Thanks,
John.
You have to link with MFC. Go to Project - > Project Property -> Configuration Properties -> In "Use of MFC" put "Use MFC in a Static Library"
