Hi,
I have created a small application in Qt (using Qt designer) and want to run it on another machine, but when I run it, I get error messages like mingwn10.dll is missing.
I know the application needs the Qt runtime, but I have not clue how to install it on the other machine.

Is it enough to copy those missing dlls to the other machine? They are large dlls and I don't think it is neccassry to copy them all only to run a programm smaller than 100 KB.

Please give me some clues, because I am an absolute beginner.
Thanks in advance.

Really?
If that is the solution, the I should say Qt is not efficient at all!
Having to copy several large dlls to run only a small application is not efficient at all.
At least there should be another way to launch those dlls, such as a single exe file or something like that.

Thanks for your reply!

Hi,
huangxinhao mentioned the easiest way out, due to you said you are a beginner. If you want to deliver your application without copying the dlls (wich is much smaller solution than .net-Framework by the way) you have two more choices:
1) you can use a installer-tool to check if there are QT-Dlls installed on your target machine and install the DLL only if they are needed.
2) use Google to find out how Qt-Applications are built 'staticly' :
example: http://doc.qt.nokia.com/4.1/deployment-w…g-qt-statically

hope this help,

Hi,
Thanks for your reply. I will give it a try, and see what happens.
Thanks again!
