Installation and Deployment

You should Never (™) copy libraries like that, you might end up overwriting your system's own copy of Qt.

i made a disco app that draws 450x450 rects in random colors, every 16ms , on linux it was supper smooth ! on windows it lagged so much, i tought its problem with my compiling or windows setting but i guess linux is better in speed :P

I have problem using qmake to cross-compile in qtcreator. Do you have a sample qmake config. I sudo get-app install qmake. I am using this qmake not the one created by buildroot. How to compile the userlandin buildroot? pls advice. My intention is to copy manually. I try following the above links but i can't find the exact "support for framebuffer device"

You're welcome ! If you have it running now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)

Hi, my image is located in the desktop. I see it before running but when running no so I don't think that the path is the problem. So I tried to put it using code and the program works correctly.Now I can se it when running :) . To notice the first method (using Qt Designer) works sometimes and sometimes no (I have tried an other example using Qt Designer and I get it when running).

[quote author="sierdzio" date="1408971065"]Hm. Maybe you don't need to specify the -arch if you are already using a 64b command line. Try again without it (you need a clean source code. Depending on how you are building, that means either extracting the .zip again, or running dist-clean, or removing your build dir).[/quote] Thank you very much! It works now.

Hi and welcome to devnet, You have to use qmake first to create a pro file then again to generate a Xcode project. Everything is explained "here":http://qt-project.org/doc/qt-5/macosx.html

Thanks SGaist, I'll give that a shot, see what comes up. hskoglund, I found out about the DBus .so from running ldd on libqxcb.so, so I added that into the project as well. Also, I didn't think about the libxcb.so file. I'll look into that for Fedora. As I said it works well on Ubuntu and even on other Debian based OSs as I've tested on several. It's the Red Hat deviations that are giving me trouble, Fedora being one of them. I'll look into this as well.

I have the same question here: http://qt-project.org/forums/viewthread/46723/

[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.
