I have a project which is using Qt 4.7.4 version (also I can't rebuild it using qt4.8 or qt5 – there are a lot of errors appears, project is big and not mine so fixing issues would be even harder than erasing the whole code and write new code). So I need to make this project, well, working on NativeClient.
Is it even possible? I use Windows and Visual Studio, I was trying to google instructions about qt+nacl on Windows but just can’t find nothing.
Also which pepper version should I use if it depends on it?
Is your qt build supporting native client?
Please check out this
Windows
The Qt-Nacl is not support, for now, in Windows.
By the way, here is the github repository dedicated for it -> https://github.com/msorvig/qt5-qtbase-nacl
In the file nacl-readme it is written :
[...] Windows is not supported as a host platform.
Linux
If you want to compile in Linux, I have made a script that will compile Qt5.4 with NaCl with all the dependencies needed.

I also made a video that will show the different steps and a showCase at the end :

I do not have the macdeployqt installed on Windows 10 alongside of the windeployqt tool. Nothing relevant or useful appears when searching about this issue so I'm forced to resort to stackoverflow.
windeployqt works fine, however the macdeployqt tool is not there. Is there a way to download the tool from somewhere possibly via the presently non working maintenance tool (due to the default repositories not working for me on QT5.11)?
The macdeploy tool's source code is shipped with Qt sources (qt-src\qttools\src\macdeployqt). Most of it's source code is within #ifdef Q_OS_DARWIN-blocks, and it's linked against Apple's CoreFoundation Framework, so I don't think you will ever get the macdeploy-tool to work on windows. Im curious how you compiled your application that you're trying to bundle; afaik you cannot cross-compile in a meaningful way as the CoreFoundation and other Mac-Frameworks are not available on any other platform.
Hi I have a debian image on BBB I have already installed QT creator on B^3 but the problem is whenever I try to start a new project in qt creator, couldn't see any option of kit. Infact when i add qmake and compiler path the application throws error.
What can I do to solve the problem. Can i directly get the full pack of SDK from qt.io/download ?
You must compile Qt libraries for your device (BBB) on your own, using specified compiler. You can find more information on this topic, here:
Qt Cross-Compilation Options
As soon as you compile Qt libraries for your device, you must move them to appropriate directories (on your BBB).
First, I would suggest learning to cross-compile, it's much faster & more easily maintained when you want to move to new versions. There's a ton of documentation and community around doing this. Windows & Linux both of which are probably dated, but info is still relavent. I've heard it's much easier from a linux host, but that could be biased.
That being said, if you don't want to cross-compile I believe you can simply install the qt embedded libraries. This question may offer some good advice. Once you have the libraries installed, you should be able to use qmake directly to create the Makefile for your project, then you can use cmake, or g++, etc.. to do the actual compiling.
You're likely going to work in command line though, I'm not sure you can run QT Creator on the BBB directly. I could be wrong.
I am a beginner to QML, just wanted to test the Hello WOrld program with it. It fails:
/home/saman# /home/saman/QtSDK/Simulator/Qt/gcc/bin/qmlviewer
Qml debugging is enabled. Only use this in a safe environment!
Cannot find any Simulator supporting Qt version 4.7.4.0.
Aborted
I need to know how to solve it.
It looks like you have not installed the Qt-SDK properly. Try to follow the installation instructions that came with the SDK or install it through your distributions package manager.
Try installing SDK (Qtcreator & Qt Kit) from https://download.qt.io/archive/qt/5.0/5.0.0/ (download required version depending on the platform you are working). This would inturn contain samples & demos which will work flawlessly.
All the best!
I've been searching for this info with no luck. I'm using SDK1 with 4.7.0. Works fine but has some issues with Postres so I need to update. The thing is...
I go to download RC SDK1.1 and I see windows version is 1.5GB!!
The Linux version is about 700MB.
Why is Win version more than double?
SDK1 was about 320MB for windows and 400MB+ for Linux.
So Windows version was relatively smaller than Linux version considerably and sdk1 was drastically smaller than sdk1.1. I hear that 1.5GB unpacks to 5GB.
Of course, if you download the framework and creator separately than it is normal size (roughly equivalent to SDK1). This just adds to confusion. Isn't the SDK == Framework + creator ?
Something is wrong here... Any ideas what is going on? Should I wait till full release version?
I think thats because only Windows supports development for Symbian platform using Symbian SDK that can be installed (other platforms use remote compiler). Nokia with Qt SDK 1.1 announcement mentioned that they refactored Symbian toolchains so now you can use Symbian ^ 1 and Symbian ^ 3 native APIs. I think that what made the installer so huge. On the web site I noticed they have web installer, so I'd recommend to download the web installer which is just 15Mb and I suppose it should be a wizzard page that allows you to select which parts to install. Just don't install Symbian native SDK or anything else you don't need.
Hope that helps
I am using Qt in order to build a cross platform GUI app (Windows and Mac). I want to be able to update the app efficiently and automatically whenever there is a new patch available.
I saw this post which got me to take a look at WyBuild. It looks great and probably what I may end up using for the Windows version but what about Mac? What are some alternatives available to me?
I've just started developing a Qt-based autoupdater called Fervor for my own needs. You can try it out, contributions are more than welcome too.
For Mac the best choice is Sparkle used by WebKit, Adium, Cyberduck and more. Its only for Mac but I guess native look matters on Mac a lot.
Not familiar with WyBuild so cannot comment. Sparkle is a fine choice but the poster preferred a single app for both platforms. BitRock InstallBuilder contains an autoupdater written in Qt that can be used independently (disclaimer, I am the original BitRock developer). It is a commercial app, but we have free licenses for open source projects.
There is Updatenode which seems to provide a real Qt cross-platform solution.
It comes with a prebuilt client for Windows, Mac and Linux. The online service lets you manage updates very easy and are able to see good charts of your application usage.
And here another one of the possibilities:
Using the Qt Installer Framework: It provides installers for Windows/Linux/Mac with an build-in updater. If you need an example - The MaintenanceTool of your Qt-Installation uses the framework.
To get an auto-updater from it, all you need to do is:
Create an online installer (Just check the documentation, it's not that hard)
Use the maintenancetool in your application to check for updates.
This cane be done using my QtAutoUpdater. Go there for more information about the whole process
If new updates are available, the maintenancetool can be started in updater mode to install the update
Update the online repository - and your update is out.
Advantages:
Installer and updater in 1 tool - this means less work for you
Easy to use (with or without the QtAutoUpdater library)
Cross-Platform for all desktop platforms supported by Qt
The installer itself is a Qt original
Disadvantages:
No "native" installers (i.e. no .msi on windows or .deb on ubuntu)
Must be used together - if you want to use the update feature, you have to use the framework as installer
This may be obvious, but for Linux you can use the built in package manager. For example, apt-get, yum, pacman, or what have you.
