Hey guys
I have a problem. I built the executable file(exe file) of my project but I cannot run it. I jut get this error:
http://upload.tehran98.com/upme/uplo...c73babe851.png
while I can run it in the QT but I cannot run it separately. I followed these two page but still nothing!:

You probably built your app with MinGW but you are trying to run it with MSVC compatible libraries. Where did you copy Qt5Core.dll from?
from this addres:Quote:

Totally, how can I make a simple exe (of my project) without any extra file?
This is a directory containing your QtCreator installation, not the one containing your Qt installation. The proper libraries are in Qt5.3.0\5.3.0\<something>\lib. Creating a build directory inside your QtCreator installation is an odd thing to do as well.
Well that was the default suggestion of QT for creating the project and so I didn't change it.Quote:

and I built my project in realese mode and when I run the program(by double click) again I get the error.
Why we cannot make our project without any other files?
QT is QuickTime.Quote:

Qt Creator is an IDE based on Qt.
Please don't mix the terms.
Did you copy the libraries?Quote:

Which libs? where are those? and also where should I paste them?Quote:

On Windows systems, use the dependency walker to identify the *exact* dll dependencies your executable will need to run correctly.
Since you're using Qt5, you may also want to use windeployqt. I haven't used it personally because I don't do Windows, but the macdeployqt counterpart for OSX is very helpful.
Good luck.
It depends. If you dynamically link to the libraries, they must be resident in a location that they can be found to successfully launch the executable. That is not specific to Qt and applies to any program.Quote:

When I first started with Qt, I thought I'd build static libraries to avoid having to deliver Qt libraries, however, I have standardized on the standard Qt distributions which are all dynamic libraries. Once you figure out how to package/distribute the Qt dynamic libraries with your app, it's really not a big deal.
Just my $.02 worth.
I am saying you should use the lowercase "t" when talking about Qt and that you should use the term "Qt Creator" when talking about the program that suggested you to create a build directory somewhere.Quote:

That's how dynamic linking works in Windows. You can copy all those libraries to your C:\Windows\system equivalent instead if you want. Just be prepared for a DLL hell ;)Quote:

This is all standard stuff, you know. Totally unrelated to Qt itself. There is also a "Deploying an Application on Windows" article in Qt reference manual telling you the basic stuff you need to know. Of course you should have known that before...Quote:

the size of release folder is 48MB. Too big!:(
Too big for what? 48MB is nothing nowadays.Quote:

Or you can benefit from the thousands of hours of coding and testing that goes into the creation/maintenance of Qt and write a fraction of the code yourself, and ship a 48MB package. As a side benefit, by using Qt, your code is portable to all major operating systems, so don't discount the benefit of that either!
I know which choice I would make!
I will never leave Qt. it's cute!:o
