@isaac321 Thanks for making sure to post the answer when you found it for others who might come along. :)

@Ram_Thakkar77 It sounds like you just don't understand linux properly. It isn't that it is harder than windows (and in a lot of cases it's actually easier), it's just that you don't understand how the program is run and how ld finds your libraries. There's a term in windows called dll hell which I'm sure you've heard. You are basically just running into a similar situation in Linux but have no idea how it works or how to solve it. I recommend you stick with it as once you figure it out it's quite easy. The info p3c0 and jsulm gave should have helped you get your distribution ready, but you kept missing libraries and not setting your custom LD path properly. If you do this correctly it is not only quite easy but can all be easily automated in a small bash script. I definitely wouldn't blame Qt for this as you have a "distributing linux binary" problem, not a Qt one. That would have happened to you no matter what development toolkit you used. It has nothing to do with Qt at all.

an answer 4 years ago ..and now took me out of rough rush of 2 hours...Thank geeks

BTW, next time, please give your thread a meaningful title. Also choosing the best fitting subforum is highly appreciated. And when your problem is solved, mark the thread accordingly. We have a small visual forum guide for newcomers: Hitchhiker's Visual Guide to the Qt Forum and there is also the Forum general guide. One more thing: The image upload feature on our forum is broken, see How to insert image on this forum for a workaround. :-)

@Zigjaz You could try to update graphics driver on that machine

@jsulm Thanks! i'll continue there!

@maroney Wow... I hate it when it ends up being hardware related. It's something I almost never suspect because it is so rare and so hard to track down. Glad you got it fixed though. :)

In case anyone cares, the resolution was to move calls to QCoreApplication::addLibraryPath() to before the QApplication is created. Qt4.8.7 did not care but Qt5.8 does.

Small note, it was due to a missing sysroot and needed the -no-opengl switch since the linaro sysroot does not contain the OpenGL enabler for the BBB.

LIBS += -Lpath/to/folder_containing_the_lib_file/ A quick look at the LIBS variable documentation would have got you the answer quicker.

Which Qt version and Qt Creator version are you using? Did you install Qt using an installer or rather you are using packages provided by Debian?

@elfredy91 They are indeed handy commands. :) Happy coding! Edit: coincidentally I believe it was firefox that I had bad downloads with before. I use chromium, opera, and now I'm checking out vivaldi for browsers.

Hi! You might be hitting a faulty mirror. You can use the QtSdkRepoChooser to change the repository where the data are checked/downloaded.

@jsulm Yeah.

Hello, I know this thread is old but I came here with the same problem and managed to solve it. By installing libqt5sql5-mysql with $ apt-get install libqt5sql5-mysql Happy coding ! :)

@configurationinquiry4 Can you execute your app without debugging?

Thank you! Finally it worked for me, nevertheless I had to include the "Frameworks" path too: QMAKE_LFLAGS += -Wl,-rpath,@loader_path/../,-rpath,@executable_path/../,-rpath,@executable_path/../Frameworks I didn't have to do this before Qt 5.1.x versions, but it feels great to know how to fix it for newer versions. Thanks for the hint! :)

Thanks for your help :)
