First, go here http://download.qt.io/online/qt5/ to figure out the url to the version of repositories you need. For me it's linux 64 bit, so I'd click down into that path until I got to http://download.qt.io/online/qt5/linux/x64/online_repository/.
Copy this url into memory.
Then, in the repositories tab of the Qt maintenance tool, select "user defined repositories" (see image in the previous post) then to the right of where you have just clicked, paste in the url you just copied. It's difficult to tell there's even a field there, it's almost hidden. When you hit the right spot the url will paste in and you should be good to go.

@aha_1980 Perfect, I shall go tell my expert friend he is talking rubbish :)

@Joachim-W Do you have c:\Qt\5.11.1\mingw53_32\lib\cmake\Qt5Gui (adapt the path to the Qt version you installed) and if so iis there anything inside?

@koahnig Hi, thank you for your answer!
I think it works now.
To be honest I don't really know why it didn't work. I tried a lot, also turning off firewall and load online and offline installer from different pages for case, that the .exe is corrupted.
Last thing I did is to check the regedit and delete all Qt*-data in HKEY_(...)\SOFTWARE. Its working now. The problem was probably because of unclean deinstallation of previous version.

@jsulm we make an installation file for our combined system, including multiple programs sharing some but not other resources. we use an nsi script to manage this. usually works fine. I just missed updating some of the .dll files.

@SGaist It worked. Thank you so much.

@JosephTLyons If you used the installed for Qt 4.2 then it probably exists in a single directory. So just like anything else on OSX you can just delete that directory and should be all uninstalled. If there is a dir outside the /Applications directory you may need to clean that up too. Sorry not 100% sure here since all my OSX Qt installs were built from source so I don't know how the installer works on OSX. On Linux it's a single directory.

Anyway, once /Applications/Qt* is deleted you should be ready to do the install from Qt 5.11. Qt4 and 5 rarely play nice together in my opinion so a nice clean install would be a good idea. You can make them work on the same system but in my experience on these forums people mix their dylibs all the time and get weird behavior, crashes, failures to load, etc. So if you want them both for some reason just make sure they stay separate.

You also have the MaintenanceTool that offers that possibility.

Is there a difference between Quick Controls and Quick Controls 2

Yes, QQ 1 was the first iteration, QQ 2 is the new one. They are not the same, QQ 2 was redesigned and implemented from scratch due to certain problems in QQ 1.

are both included in the initial installation

Yes.

@ajcurtis said in QtCreator can not load plugins UBuntu 16.04:

QApplication: invalid style override passed, ignoring it.

But it is running now? If so then just ignore that warning.

@rggarcia said in Qt 5.8 installation - MacOS Sierra:

qtpcre_debug

Looks like qtpcre_debug was not built. Did you have any errors while compiling? Do you have to build Qt by yourself?

Following that wiki entry, recent versions of the Android NDK are problematic. It is recommended to use ndk-r10e.

I found qtlicense, i deleted this file. But nothing happens.

Then i create a new account on Qt installer, and re-install the open source version.
That did the trick. Many thanks Dheerendra.

Regards, Nahuel.

Did you install MSVC2015 before or after Qt ?

Can you see it in the Compilers tab ?

Thanks, contacted @alex_malyu directly.

offline and MinGW

That is what I was thinking regarding the compatibility of the two versions, I will attempt the change and let you know

@Ratzz spam, it's been removed.

I found the answer. The problem is that the QtWebKit.framework bundle requires some of these other ones, even though I might not be using them. The only fix would be to acquire the QtWebKit.framework project, remove the QML and Quick dependencies, recompile, swap that framework bundle out of my project after macdeployqt, and then remove the QML and Quick framework bundles.

Long story short, that ain't happening. Not worth my time because it's super difficult.

I stumbled upon this answer and added those links found in this this xml file:

http://download.qt-project.org/online/qtsdkrepository/linux_x64/desktop/tools_maintenance http://download.qt-project.org/online/qtsdkrepository/linux_x64/root/qt

Now I have repositories configured and everything is fine.

Hi and welcome to devnet,

You can use QtSdkRepoChooser to try another mirror.

Hope it helps

@jitu059_Lalat The long and short if it are, you have two ways to do this:

Find all the dll's that your app depends on. You can do this with the tool http://www.dependencywalker.com/. Once you found all the dll's copy them into the same folder as your executable. This is now your "delivery package" you will copy the executable + dlls from PC to PC. This method is perhaps a bit easier/faster in the short term, but when you compile with different versions of Qt/Windows you may require a different set of dlls (i.e. Qt4 Dlls don't match Qt5 Dlls).

Download the Qt source code and compile it for static linking. Then when you build your code you will get a much larger executable file, but it will contain everything it needs - a standalone executable. This is perhaps a bit more work on your part, but master this and it makes deploying your project from PC to PC much easier.

Have a go at one or other method, if you get stuck then ask again. But as SGaist said, there is lots of documentation out there already : )

I find the reason:
in these way this error occurred :
1- the permission of file : the output of tslib should has full permission :chmod -R 777 /.../.../tslib
2- the address of tslib is wrong. if you write wrong address this error display
3-if you install tslib successfully , and then remove it and install it gain this error show you. i change my linux and install another one but should clean all the tslib file and details.

Thanks SGaist, I built it on my end and seem to be working alright.

You can find usefull starting informations here

ok found the solution:

in my .pro i hat a typo:

target.files = config.conf .... // wrong _____________^_________

this needs to be:

target.files += config.conf // right _____________^_________

also I hade multiple installation-targets and did not add target to installs in every build configuration.

so for those who run in the same problem:

be sure you add target to INSTALLS, target.files is already filled with your compilation output. use += not = to add other files

Hi and welcome to devnet,

To the best of my knowledge, what you want to do is only possible through the online installer

Hi @enjoysmath, and welcome to the Qt Dev Net!

Your download mirror might be having problems. You can use this tool to choose a different mirror: https://forum.qt.io/topic/43349/

Hi @JKSH,
I know about the proxy settings of the MaintenanceTool.exe but did not find any possibility for setting a proxy in the QtSdkRepoChooser.exe tool :-(
Anyway, thanks for the tip with the Interest mailing list. I will try there.
Ciao Wolfgang

Try downloading it from here or from one of the mirrors closest to your location. It's gonna be in /official_releases/vsaddin sub-directory.

By just uncommenting the line:
#INSTALLS += target additional

in mapviewer.pro,

It runs up and shows the map on my android phone, great!

This problem has been resolved. Apparently, the libraries available in the distribution are not compatible with each other, or with installation of "sip" or "PyQt5". After installing the .deb file found at http://tinyurl.com/kza5uob and remaking the current stable versions of "sip" and "PyQt5" I was able to load and execute an application originally run on Fedora 19.
