Installation and Deployment

@jsulm Ha! They're up to rev 5 now, and that fixed my problem. Thanks!

Clang has become the default compiler since Xcode 4.2 and the only one available since 5.0.

Thanks !!! 0_1519092448346_pic.png

@Hetal Use Qt Online Installer and select one of the packages starting with UWP (which exactly depends on your Visual Studio version and platforms you want to support).

@drhalftone It sounds like you don't have your kit set up properly. That is where you point it at the compiler you want to use. Check that in settings and make sure you have a kit and there are no red exclamations.

Yes, I do have multiple versions installed, but I made sure to compile and windeploy with the correct ones. In any case, with your advice, we were able to solve the issue: void openDatabase(const QString &databasePath) { static bool initialized = false; QSqlDatabase database; if (!initialized) { database = QSqlDatabase::addDatabase("QSQLITE"); initialized = true; } else { database = QSqlDatabase::database(); } With this, the error is gone and the program works both with and without windeployqt. As you said, we only use this in the openDatabase function. Thank you for your advice! In retrospect the solution is rather obvious, but the strange behavior with windeploy really got us confused :)

@sierdzio Thank you very much. I didn't know about QWt. I hope it is good, otherwise i will have to switch to C#/WPF. Greetings

@biswasp said in Make: Nothing to be done for 'first': "make: Nothing to be done for 'first'" This isn't a problem. As already said in this thread it means that the project is already built and up to date. If you app doesn't start then you have another problem. Build your app in Debug mode and then try to start it with debugger pressing F5. Maybe it simply crashes or some DLLs are missing.

Can you show your .pro file ?

@paulgc None of them. As @JKSH already said you need to build Qt by yourself for your target device. There is no official Qt build for your device (it is not possible to provide Qt binaries for all existing devices).

@smartonion https://msdn.microsoft.com/en-us/library/y19zxzb2.aspx INTERNAL COMPILER ERROR(compiler file file, line number) Can you show your code you're trying to compile? And as @SGaist said: please provide more information.

Yep that did it. I didn't sign the package. Won't do that again in a hurry. Thank you guys

@koahnig You're right, I think I'll go for it. Thx for your time et your help anyway.

@_BXL_ sorry as this is no standard QtCreator I cannot help you. Maybe the ROS plugin maintainers can.

Hi and welcome to devnet, What exact version of Qt did you install ? If it's one of the Visual Studio version, did you first install the corresponding Visual Studio edition ? Including the C++ tools ? If you don't have VS installed, the usual fast way is to select the MinGW edition for which Qt provides the corresponding compiler so you can start right away (no, it can't do that for VS, it's forbidden by Microsoft).

Hi, Use the amd64 command prompt when building Qt.

@teux said in Plugin errors, & can't set path with qt.conf.: (libts-0.0.so.0: cannot open shared object file: No such file or directory) you problem seems that the eglfs plugin doesn't load, because it can't find the dependency to libts?

@Rajarshi Did you try what @JKSH suggested in the topic you linked?

@SGaist Thanks. I see now how to drill down.
