Installation and Deployment

[quote author="bootchk" date="1401976977"]It seems that argv[0] on a sandboxed app returns just the app name, not a path, e.g. 'myApp' instead of .../Contents/MacOS/myApp. So Paul's solution above doesn't work on a sandboxed app.[/quote] What version of Qt? I am using 5.3 and I am getting the entire path from argv[0]. However, one interesting thing is that the line: QDir dir(argv[0]); Will initialize 'dir' with the appname as another folder. Hence, if argv is: /Applications/MyApp/Contents/MacOS/MyApp, QDir will treat that as a folder and you essentially have to cdUp 3 times.

Hi and welcome to devnet, Depending on where you are located you might be directed to a faulty mirror. The online installer might also be a good alternative. Anyway, glad you could finally install it. Since all is ok, please update the thread title prepending [solved] so other forum users may know a solution has been found :)

Hi, I haven't yet any experience with WP8.X but did you took a look at this "wiki":http://qt-project.org/wiki/WinRTBuild entry and the links provided ? Hope it helps

Hi and welcome to devnet, No, there are also pre-built packages for Qt 4 however there are more versions for Qt 5 due to more platform/compiler combinations supported. For Qt 5 you also have the online installer which allows you to select several version of Qt to install e.g. Desktop, Android etc. Sure you can build it, the documentation provides all necessary informations and you can also find the instructions on this site if you want to build from git's sources.

Ah, right. Will do. Thanks for the quick reply!

when cross-compiling QT 4.8 for ubuntu you need to enable MYSQL if done then you need to install MYSQL driver for ubuntu go to ubuntu software center from your beagle bone and install libqt4-sql-mysql or simply connect beaglebone to internet simply and type sudo apt-get install libqt4-sql-mysql in terminal the driver will get installed before this ensure that you have installed MYSQL server on beagle bone or do that by typing sudo apt-get install mysql-server*

Good work, ondrejandrej. Take care!

Has anyone solved this problem? Im having crosscompile issues with MySQL on beaglebone black

Hi, You are probably getting connected to a bad download mirror. See https://github.com/JKSH/QtSdkRepoChooser on how to choose a different mirror.

Thank you, seems to be working now, also fixed my empty welcome screen.

Thanks, I figured it out once you told me where to go. I didn't realize that all the tabs on the top of the Project section were for the kits.

Hi, Glad you found out and thanks for sharing. Can you also please update the thread title prepending [solved] so other forum users may know a solution has been found :)

Welcome to DevNet! I assume that you use latest (3.1) QtCreator Please take a look "here":http://qt-project.org/doc/qtcreator-3.1/creator-debugger-engines.html for "Setting Up Debugger" instructions and "here":http://qt-project.org/doc/qtcreator-3.1/creator-debugging.html for general debugging instructions.

Yeah seems a bit convoluted. Thanks for explaination! I guess I will re-distribute it just for the sake of it. Apart from that I think ThirdPartySoftware_Listing.txt should also be re-distributed...

[quote author="ProgrammerAtHeart3344" date="1407083249"]I downloaded the visual studio add-in for 2013 but doesn't seem to find the directory of Qt.[/quote]You need to tell it where to find the directory of Qt. See this tutorial: http://www.bogotobogo.com/Qt/Qt5_Visual_Studio_Add_in.php Also, are you using the Visual Studio IDE or the console?

Hi, If we have this scenario... Using Wacom drivers kills Qt applications Using Wacom drivers kills Call of Duty Using Qt applications does not kill Call of Duty ...then we can conclude that the problem is caused by the Wacom drivers, not Qt.

You have a Desktop kit and a Wandboard kit. Which one did you use to compile your application? I 'm using the destop computer to cross-compile for the arm (wandboard)* You are using make from /opt/poky/1.6.1/sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/. Shouldn’t you be using /opt/poky/1.6.1/sysroots/i686-pokysdk-linux/ ? (Make sure you know which files should be used in your desktop, and which files should be used in your Wandboard) I just had a quick search in the folder /opt/poky/1.6.1/sysroots/i686-pokysdk-linux/ for make . I don't find any make file there. Also i tried to use the /usr/bin/make with this i'm getting the following error 15:38:40: Running steps for project clocks... 15:38:40: Configuration unchanged, skipping qmake step. 15:38:40: Starting: "/usr/bin/make" clean rm -f qrc_clocks.cpp make: rm: Command not found rm -f main.o qrc_clocks.o rm -f *~ core *.core make: [compiler_rcc_clean] Error 127 (ignored) make: rm: Command not found make: [clean] Error 127 (ignored) /bin/sh: 1: rm: not found make: [clean] Error 127 (ignored) 15:38:40: The process "/usr/bin/make" exited normally. 15:38:40: Starting: "/usr/bin/make" make make: *** No rule to make target `make'.

I just cant figure out wants qt-creator is errorously set by me which is creating the problem. can you please suggest. Thanks Nilesh Kokane

Ok, I've resolved the issue. In my AndroidManifest.xml file I was double-declaring the android:screenOrientation tag. I had android:screenOrientation="unspecified" and on top of that I also had android:screenOrientation="landscape". I successfully reproduced and fixed the error by doubling and removing the android:screenOrientation tag intentionally. I am using Qt 5.3.1. So to other people experiencing the error, double check your XML file. Make sure you clean your build directory. I just delete the whole directory and it just gets recreated. I'd be interested to know if other people did get it fixed and how. Cheers

Hi, Had the same problem and after instaling libdbus-1-dev the problem got solved
