@VinayVerma Were you able to find a solution to the above problem? I am facing the exact same issue.

For the recored, filed QTBUG-53845

Hi, One thing that you could try is to add a custom target that will call windeployqt on your target. Something a bit like the tests target when using Qt's unit tests module. Hope it helps

I tested in Ubuntu 14.04 up to 15.10 and the tray icon is still not shown. The systray whitelist is not available any more in those distributions though, and I'd rather not have to install packages that bring back the tray icon like https://launchpad.net/~gurqn/+archive/ubuntu/systray-trusty. I thought Qt 5.4.2 already supported app indicators?

Hi, For qmake you can use something like: INCLUDEPATH += /path/to/OpenCV/include/folder LIBS += -L/path/to/OpenCV/lib/folder \ -lopencv_coreXXX \ -lopencv_imgprocXXX \ -lopencv_highguiXXX \ # next OpenCV libs you need Note that you can also setup your project on your Windows machine using either qmake or cmake and once it's building there, bring it over to your Linux target, and add the Linux specific pieces to link to OpenCV

Hi, You have to port the CMakeLists.txt for Qt 5. You have the CMake Manual in Qt's documentation to help you get started.

might be slightly more compact to use the fill method. :) http://doc.qt.io/qt-5/qstring.html#fill

It's because you don't implement them. Also note that these function are valid only for QGLWidget and QOpenGLWidget. Do you have a QApplication instantiated in your main function ?

Hi, Windows 64 bit is able to run 32bit applications. What exact error do you get ? Did you setup all android environment variables ?

Well, I figured out, that in my case it was stupid mistake of using MSVC windeployqt with MinGW compiled app.

@SGaist thanks for reply) I understand that I need that for deployment on device but I am building just qt not an app. So i thought it might be unnecessary for building Qt itself. Cause when i am downloading qt for Ios i don't need to have that account. But i need it to build qt that's strange for me. I have ready code to port to ios so openssl is needed

@Paul-H. D'oh! Why, of course, how silly of me. visibility: Window.AutomaticVisibility does NOT automatically do visible: true. Truly a case of needing to ask someone else to realize you're making a rookie mistake. Thanks for your help, Paul.

@islam-ouahouda Try this, http://seppemagiels.com/blog/create-mysql-driver-qt5-windows it worked for me

Hello' Again, I've decided to try it over MinGW compiler and a static build, apparently it got better but still have some errors. Here is my .pro file: QT += core gui widgets TARGET = Launcher TEMPLATE = app SOURCES += main.cpp mainwindow.cpp HEADERS += mainwindow.h FORMS += mainwindow.ui DEFINES += CURL_STATICLIB LIBS += -L"C:/Users/Banzai/Desktop/C++/QtPgrm/Mingw Real/includes/curl" -lcurl LIBS += "C:/Users/Banzai/Desktop/C++/QtPgrm/Mingw Real/includes/curl/libcurl.a" LIBS += "C:/Users/Banzai/Desktop/C++/QtPgrm/Mingw Real/includes/curl/libcurldll.a" INCLUDEPATH += "C:/Users/Banzai/Desktop/C++/QtPgrm/Mingw Real/includes" Also '#define CURL_STATICLIB' is declared in the header before the include of cURL. Here is the error I got: error: undefined reference to `curl_easy_init'. Not too sure what it could be. (I am using the 64 bits version while the compiler is 32 bits). When I've been using the 32 bits version, here is what I got: undefined reference to {WSAStartup@8,WSACleanup@0} <path>/curl/libcurl.a(easy.o): bad reloc address 0x0 in section `.data'. Apparently I've ready somewhere that I had to include something with -lwsock32, which I did this way: LIBS += -lwsock32 Unfortunately it did not seem to change anything. Thank you for your help.

For the people googleing this issue. There is documentation abut this in qtbase/src/network/ssl/ssl.pri: Add optional SSL libs # Static linking of OpenSSL with msvc: # - Binaries http://slproweb.com/products/Win32OpenSSL.html # - also needs -lUser32 -lAdvapi32 -lGdi32 -lCrypt32 # - libs in <OPENSSL_DIR>\lib\VC\static # - configure: -openssl -openssl-linked -I <OPENSSL_DIR>\include -L <OPENSSL_DIR>\lib\VC\static OPENSSL_LIBS="-lUser32 -lAdvapi32 -lGdi32" OPENSSL_LIBS_DEBUG="-lssleay32MDd -llibeay32MDd" OPENSSL_LIBS_RELEASE="-lssleay32MD -llibeay32MD"

Nop, sorry, I don't

Thanks! It works!

at funtion gerarRelatorio i swap the qDeleteAll on line down(original position). and it worked. qDebug()<<"Documentos processados para a Tabela de Relatorio"; acessodb::setDataUltimoRelatorio(idEmpresa,idCliente); qDeleteAll(listaDocumentos); listaDocumentos.clear(); delete modelo; return true; I now will upload to my test server, and see what happens. i doesn't care any more about what is causing the problem, i just hope that is solved.

If you want to use the script you can simply copy the content show in the documentation and put it in a script that has the same name as your application.

Oh, I know, I've reported quite a few bugs over the years. What I was saying is that I didn't find any reference to this issue on Jira. By the way, I have a workaround for the issue. I've attempted debugging Qt sources on the machine where loading qwindows.dll fails, and noticed that QCoreApplication::libraryPaths returns empty list, while it does return a valid path on the machine where it works fine. So, I added this one line to the main function before QApplication is created: if (argc >= 1 && argv != nullptr) QCoreApplication::addLibraryPath(QFileInfo(argv[0]).absolutePath()); And now my application runs again, on all the PCs where I've tested it!
