Basic deployment question
Sorry if it is too basic to ask in this forum
I have Qt application, I am deploying it on different desktop, i copy every thing (exe , all required Qt dll )in one folder it works (keeping plug in in another dir in parent dir), but when I am integrating my Qt app(which is a tool for big app) and copying Qt dll in different folder and my Qt app.exe in different folder it is not working. Do I need to register my dll ( i thought this regsvr32 stuff is for COM only)
This structure works: C:\MainApp\App\Tool(Qtapp.exe All Qt dll and imageformats/pluing dll )
My final Dir strucuture is like this which does not work
C:\MainApp\lib\ ( here I have all my Qt dll and imageformats\plugin dll)
C:\MainApp\App\Tool(my Qt app is here)
What do i need to do to make it working I saw this "link":http://qt-project.org/doc/qt-4.8/deployment-windows.html but it does not help
Have you try?:
It didn't help?
No but if I do this, then wont I again make my app and restricted to this dir structure?
now I am wondering how I should make my app totally independent from this path stuff. Is this possible at all to keep my exe at my own desired location and lib at totally different location .
I mean at deploy time can I really decide this path or do i always have to use addLibraryPath stuff?
In theory (i haven't try this :) ) when you start your application you can read path from some *.ini file or register, and call QApplication::addLibraryPath() or QApplication::setLibraryPaths().
Better go with:
qApp->addLibraryPath(qApp->applicationDirPath() + "/../../../lib");
This prevents surprises when you launch your app from a link, or from different $PWD (
