[Solved] Qt application not start on another computer.

[Kantong]

With qt4 I add a.addLibraryPath(QCoreApplication::applicationDirPath ()+"/plugins").
If compiling with qt 5 application dont start.
I think that the problem is plugins directory.

Hi! You have given very little information.
On what platform you work and what compiler are you using?
How you deploy your application on another computer?

[Kantong]

I use qt rc2 and qt creator with visual studio 2010 in windows 8.
I put excutable and shared dll and plugin dir.
Add path plugins as qt4.

[sierdzio]

You need to copy the platform plugin, too (windows.dll, to plugins/platforms).

[Kantong]

Done. Dont start.
Qt is great and there is good documentation, but things easy seem complicated.
Excuse for my english.

[Kantong]

Phatic months for an application and I cannot give to friends!

On the other machine must be installed Microsoft Visual C++ 2010 Redistributable Package, which can be downloaded "here":http://www.microsoft.com/en-us/download/details.aspx?id=5555.

I know this. I believe that the problem is plugins dir.
In fact, if you rename in my computer this folder, application not start.
I put in folder application shared dll and copy in it intere plugins folder, add
istruction a.addLibraryPath. I try to delete other path library.
In qt 4 version this work, in qt 5 lib not work.
There is a solution, probabily, as add plugins folder in same directory in client computer, but I belive is not elegant solution.

[Kantong]

Solved! Don't need add anything to code application, example addLibraryPath,
I have put in folder release follow files:
D3DCompiler_43.dll
icu*.dll
libEGL.dll
libGLESv2.dll
and other which application ask.
The plugins folders must out as same level:
not plugins/imageformats
but imageformats

Add also platforms
Thanks

This is good news! Now be a good boy, and add [Solved] to the beginning of a stream header.
When I create the installer on Windows, use the "Dependency Walker":http://www.dependencywalker.com/ .
This is a GUI application that shows the dependencies needed to run the application (this does not apply to plug-ins).
