    Problem solved for the Galaxy Tab 3 10.1: The tab only emulates armeabi so the application works if i use qt's dynamic linking, but fails if i use ministro since ministro will download the necessary x86 librarys for the armeabiv7a application.

    Indeed I have those permissions : @ <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/> <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>@ Whent the socket state is ClosingState or UnconnectedState the socket error is "Transport endpoint is not connected"

    Hi, Maybe you can also multitasking using a QThread and check there all the interrupts, if something happen, you can emit a signal @ class Interrupt: public QThread{ Q_OBJECT public: void setNextEvent(bool arg); bool getNextEvent(); protected: void run(); private: QMutex mMutex; bool state; signals: void mySignal(); } @ @void Interrupt::run(){ while(true){ if(rpiGpio.readPin(17) == mmapGpio::LOW && getNextEvent()){ setNextEvent(false); emit mySignal(); } else if(rpiGpio.readPin(17) == mmapGpio::HIGH && !getNextEvent() ){ setNextEvent(true); } QThread::msleep(100); } } void Interrupt::setNextEvent(bool arg){ mMutex.lock(); state = arg; mMutex.unlock(); } bool Interrupt::getNextEvent(){ bool ret; mMutex.lock(); ret = state; mMutex.unlock(); return state; } @

    Thanks for reply. I just started to build qmake in Windows, but I've got a problem: make process unexpected crashes with the message: @This is the Qt for Windows Open Source Edition. You have already accepted the terms of the license. Creating qmake... Makefile:13: *** missing separator. Stop. Makefile:13: *** missing separator. Stop. Cleaning qmake failed, return code 2 @ The part of qmake Makefile is: @#AutoGenerated by configure.exe BUILD_PATH = F:\Qt\qt-5.3.1\qtbase SOURCE_PATH = F:\Qt\qt-5.3.1\qtbase INC_PATH = F:\Qt\qt-5.3.1\qtbase\include QT_VERSION = 5.3.1 QMAKESPEC = linux-arm-gnueabi-g++ !IF "$(QMAKESPEC)" == "win32-msvc" || "$(QMAKESPEC)" == "win32-msvc.net" || "$(QMAKESPEC)" == "win32-msvc2002" || "$(QMAKESPEC)" == "win32-msvc2003" || "$(QMAKESPEC)" == "win32-msvc2005" || "$(QMAKESPEC)" == "win32-msvc2008" || "$(QMAKESPEC)" == "win32-msvc2010" || "$(QMAKESPEC)" == "win32-msvc2012" || "$(QMAKESPEC)" == "win32-msvc2013" || "$(QMAKESPEC)" == "win32-icc" !if "$(SOURCE_PATH)" == "" SOURCE_PATH = .. !endif !if "$(BUILD_PATH)" == "" BUILD_PATH = .. !endif QMKSRC = $(SOURCE_PATH)\qmake specific stuff for NMake and ICC !if "$(QMAKESPEC)" == "win32-icc" CXX = icl LINKER = link CFLAGS = /Zc:forScope !else CXX = cl LINKER = link !endif @ What the problem?

    Hi, I have found the reason for the failing linker call. In my environment CC, LD, etc. were declared as read only variables. Therefore the cross compile environment in the linux_device_pre.conf cannot be setuped correctly. linux_device_pre.conf : QMAKE_LINK = $${QMAKE_CXX} This means Qt calls normally the linker with the g++ frontend and not directly ld. Now a lot of headers files were not found and I have to add the Qt include directories to the configure call. For example why I have to add "-I include/QtCore" to the configure call? It is part of the Qt framework. Falcon83

    [Solved] I am not sure why this it works. My iOS app folder is named TSR.app. My app folder contained a Contents/MacOS/ folder ( I build this app for both iOS and OSX) The fix was to copy the following two files from the application folder root into the subfolder named /Contents/MacOS as shown in the tree below. Info.plist PkgInfo Here is what my Qt5.2 build directory looked like. @ build-tsr-iphoneos_clang_Qt_5_2_1_for_iOS-Debug ├── Debug-iphonesimulator    └── TSR.app ├── Contents │   ├── Info.plist │   ├── MacOS │   └── PkgInfo ├── Default-568h@2x.png ├── Info.plist ├── PkgInfo └── TSR @

    [quote author="gabrieltb" date="1406310520"]I apologize for my lazy answer. What I meant is that you can try using relative values for width and height. @width: Screen.width height: Screen.height@ Also, take a look "here":http://qt-project.org/doc/qt-5/scalability.html You'll find a section talking about screen orientation.[/quote] Worked! Thank you so much budd :)
