How to run my Qt Application on another pc? Problem with QtCore4.dll

[Mega69]

Hello,
yesterday I've succesfully installed the latest version of qt creator ( on windows xp sp2 ).

After creating a project, I have to select the "green arrow" in order to compile and then launch the program.

But if I want to launch the program from the folder where the .exe file is ( for example, C:\Qt\MyProj ), simply by double-clicking on the .exe file, I have to have installed the .dll "QTCore4.dll" into my "C:\Windows\System32" folder ( otherwise I get this error message: "Can't find the point of entrance for the procedure _z5qFreePv in the dynamic links library QtCore4.dll" ).

So, if I want to execute this program on another pc, in this pc I have also to install the right .dll in its System32 folder.

Is there any way to do this automatically? Like an installer ?
Or I'm just missing something?

Thanks, and sorry for my bad english.


PS:
In system32 I have to put not only QtCore4.dll, but also QtGui4.dll

I found out that maybe I need to make a static build, someone could explain me how to do it?
(My compiler is mingw)

You can place the libraries not in the system folder but in the same folder your application is copied into.

Thanks, this works.

However I would like to understand how to make a static build, because I try to put this on my .pro file

CONFIG += staticlib

CONFIG += staticlib

To copy to clipboard, switch view to plain text mode 

but i can only get a shared build.

You need to build Qt in static mode as well.

I noticed in your first post you mentioned the possible use of an installer. Using an installer is always a good choice. It gives your application:

1. a professional appearance

2. makes it much easier for the user

3. allows you to test and set up a correct install experience before giving it to a user

I highly recommend the BitRock installer, its free, and has different versions for different platforms.

And, no, I am not an employee of BitRock.

Good Luck

X wysota:

I tried to do what is written in the wiki, but after writing in the console "configure -static", the console doesn't allow me to write anything else ( so I can't write mingw32-make sub-src )


X Chisum:
This installer seems well made and simple to use, maybe this would be the best solution.
I'll give it a look.
