Installation and Deployment

CALL C:\Qt\Qt5.12.1\5.12.1\msvc2017_64\bin\windeployqt.exe MyApp.exe --qmldir "D:\MyApp\Application\Qml" is working fine

Okay, I think the problem here is that I was doing 'jom release' when I built it and that just doesn't seem to work. If I just do 'jom', it seems to work fine.

hi, thanks for the heads up so i ended up retrieving the old macbook and installed Qt build the app on it. thanks

Yup, that's it. Turns out I can add a qt.conf file "next" to the qmake.exe with the following in it: [Paths] Prefix = f:/5.12.1-32-release And now I get: F:\5.12.1-32-release\bin>qmake --version QMake version 3.1 Using Qt version 5.12.1 in f:/5.12.1-32-release/lib And Qt Creator is very happy.

@iieklund It should be 131.188.12.211 in my case. Apparently University of Erlangen However, this time behaviour has changed. The download of meta was still a bit slow. Apprently the complete list was downloaded and I have started to add qt5.12.1 since it was this time possible.

@ed00 I don't know Qt Maintenance Tool works for me.

Solution found for MacOS and iOS. It's might be working well for another platforms. I haven't tested it yet. Every library that is using by libzip should be added manually to the QT project and if it's not by default in the system you need to build it like static. If there zlib - then add it manually, if there SSL - then add it manually, etc The step-by-step guidance for building libzip published by me on Github There are couple of strange things that I found (I don't know the cause of it): In the directory where located library appeared couple of symlinks on the real shared library file when I am attaching it to QT project via symlinks it's not working, only direct original file attaching to project working well (it's mean important for attaching zlib from system folder). See the screenshot [image: 7d3eb179-2d62-4daf-bf31-b8472b35cfbd.png] The libzip library only working when you attaching it to QT Project like statical library (*.a), all of attempts of using like shared/dynamic libraray (*.dylib) have got failed, even it's installed like the operational system part. Code from that works for me *.pro file: macx { LIBS += -lz.1 LIBS += -L$$PWD/libs/libzip/ -lzipstatic INCLUDEPATH += $$PWD/libs/libzip DEPENDPATH += $$PWD/libs/libzip PRE_TARGETDEPS += $$PWD/libs/libzip/libzipstatic.a } ios { LIBS += -lz.1 LIBS += -L$$PWD/libs/libzip/ -lzipstatic INCLUDEPATH += $$PWD/libs/libzip DEPENDPATH += $$PWD/libs/libzip PRE_TARGETDEPS += $$PWD/libs/libzip/libzipstatic.a } SUPER-MEGA-HUGE (SMH) thanks to Thomas Klausner (one of authors of libzip). He has been helping me to solve this trouble.

Hi, You need to add the DYLD_LIBRARY_PATH environment variable in the Run part of the project panel and point it to the folder where that library is located.

Hello, but i think it´s not very cool because i only able to build because i use the configuration ~/raspi/qt5/bin/qmake -r QMAKE_CFLAGS="-march=armv8-a -mtune=cortex-a53" and i run my application and i have the first error. glGetError 0x506 [6069:6105:0228/124507.705219:ERROR:gles2_cmd_decoder.cc(2523)] [.RenderWorker-0x15bcb0]GL ERROR :GL_INVALID_FRAMEBUFFER_OPERATION : GLES2DecoderImpl::DoBindTexImage2DCHROMIUM: <- error from previous GL command may be it´s because i use "-march=armv8-a -mtune=cortex-a53" ? Thanks

@csg1 said in Unsupported Qt version, 5.9+ is required: There is only one kit installed, I assume the first one is overwritten. You did not uninstall Qt 4.8.7, so it still exists in your system. It is not overwritten. Follow @SGaist's latest instructions to switch to Qt 5.11.3.

Using the sourcecode qt-everywhere-src-5.12.0 will be fine. https://mechatronicsblog.com/cross-compile-and-deploy-qt-5-12-for-raspberry-pi/ If the sourcecode version newer than 5.12.0, it must getting "The OpenGL functionality tests failed!" Error. None of [libGLESv2.so libGLESv2.a] found in [/home/alex/raspi/sysroot/usr/lib/arm-linux-gnueabihf] and global paths. => source produced no result. I have check those files is really exist, but system can not detected.

@SGaist Thank you very much for the tip

Hi @MAX_SWEAT, glad you got it working! Can you show us the updated pro file? I'd like to fix the example so it works out of the box. Thanks

@SGaist Sure thing; Also, so if anyone else comes across this with a similar issue, i should mention that my command was somewhat off, but barely. The exact command was install_name_tool -change /usr/local/mysql/lib/libmysqlclient.20.dylib /usr/local/Cellar/mysql/8.0.15/lib/libmysqlclient.dylib libqsqlmysql.dylib

@koahnig Thanks for your help, I'll try the pre-built version of Qt 5.12.1

@PaulR I don't do any "Qt web server app", so I don't know if that has any special requirements, but just to say I do all my Qt install stuff just from the release version for Ubuntu 18.04 via apt-get (including apt-get qt5-default, plus any extras I then find I need) and never do any source/compiling. Simplez :)

@abhay Hey mate. I ve been going through the same issue recently. Tried it all but nothing really works. Would you care to let me know what were the actual steps you took in detail, so I can check where I am missing? Only if you remember of course. It has been a while. Cheers mate!!
