    Use whole Qt source code, not only qtbase. Qtbase contains only some basic modules like QtNetwork, QtCore etc. No widgets, no qml, etc.

    Here's a short script to get you going with full Qt:

    export QTVER=5.11.1
    wget http://download.qt.io/official_releases/qt/5.11/$QTVER/single/qt-everywhere-src-$QTVER.tar.xz
    tar -xaf qt-everywhere-src-$QTVER.tar.xz
    mv qt-everywhere-src-$QTVER $QTVER-src
    mkdir qtbuild
    cd qtbuild
    ../$QTVER-src/configure -device linux-rasp-pi3-g++ -opengl es2 -confirm-license -opensource -release -nomake examples -skip qtwebview -skip qt3d -skip qtquick1 -skip qtwayland -skip qtvirtualkeyboard -skip qtwebchannel -skip qtwebengine -skip qtscript -skip qtscxml -skip qtspeech -skip qtpurchasing -skip qtgamepad -skip qtserialbus -skip qtlocation -no-use-gold-linker -device-option CROSS_COMPILE=/path/toi/your/toolchain- -sysroot /path/to/your/sysroot -prefix /home/pi/$QTVER-cross -extprefix $PWD//../$QTVER-cross -hostprefix $PWD/../$QTVER-build -v

        Does not matter how you get Qt sources (from git like in your link or from archive like in my script), the result will be the same. Just remember to add all those -skip flags to configure line (and keep your sysroot and toolchain from the EGLFS guide).

          I have tried to compile Qt build for Qt_V5.7.1,but I m facing the below error

          .obj/qeglfskmsintegration.o:(.data.rel.ro+0x74): undefined reference to `QEGLDeviceIntegration::destroyNativeWindow(void*)'
          collect2: error: ld returned 1 exit status

          Can I know which plugins/lib are missing or which lib I need to install?

            Note: Dropped compiler flags '-pthread' when detecting library 'glib'.

            Note: Dropped compiler flags '-pthread' when detecting library 'gstreamer'.

            Note: Dropped compiler flags '-pthread' when detecting library 'gstreamer_app'.

            Qt is now configured for building. Just run 'make'.
            Once everything is built, you must run 'make install'.
            Qt will be installed into '/home/user/raspi_QtBuild/qt5pi'.

            Prior to reconfiguration, make sure you remove any leftovers from
            the previous build.

              Why do you say you're compiling Qt 5.7.1 when the output you paste indicates 5.11.1?

              Anyway, I've never seen that error, I don't know how to fix it.

                  This comes from EGL headers. You probably don't have all Qt dependencies installed in your sysroot.

                  1. Install necessary dependencies. Try with sudo apt build-dep qt5-qmake qt5-default on your Raspberry Pi. You may also try sudo apt install "^libxcb.*" libx11-xcb-dev libglu1-mesa-dev libxrender-dev libatspi2.0-dev libdbus-1-dev.
                  2. Update your sysroot and fix symlinks.
                  3. Recompile Qt. Make sure to check configure output that it says EGL support is on.

                    Hi ,
                    Finally it got compiled...I m success on compiling and installing Qt-V5.11.1
                    Now,please suggest me that which qmake shall I take to compile qwt-6.1.3

                    I m finding two qmake

                    1. /home/user/raspi_QtBuild/Qtver-5.11.1/qtbase/bin/qmake
                    2. /home/user/raspi_QtBuild/qt5/bin/

                    Thanks In advance for your help& support.

                      @shivaVMC said in Qwt from Windows to Linux Porting:

                      -hostprefix ~/raspi_QtBuild/qt5

                      This is your host prefix, so you should use the qmake from /home/user/raspi_QtBuild/qt5/bin/.

                      You can verify which Qt version that qmake comes from by running:

                      /home/user/raspi_QtBuild/qt5/bin/qmake -version

                        .qmake.stash is created

                        then when I perform

                        I get below error's ,please suggest on this

                        I m head cracking on this,even I did on raspberrypi3 board

                        sudo apt-get update
                        sudo apt-get upgrade
                        sudo apt-get install mesa-utils

                        sudo raspi-config
                        Select 7 Advance Options
                        A6 GL Drivers
                        selected GL (Full KMS) Desktop Drivers
                        Ok-> Finish->Reboot.
                        My Screen went black with cursor blinking.

                        Any other commands,that I can do to get support for this libQt5OpenGL...This is the only step I stuck to complete the things of my project

                          Hm, I've never seen this error message, so I can only guess.

                          Can you show build output (for Qwt) - I'd like to see at least one line calling the compiler and one line calling the linker. Need to know if all the compilation flags are correct.

                            Hm, I've never seen this error message, so I can only guess.

                            Can you show build output (for Qwt) - I'd like to see at least one line calling the compiler and one line calling the linker. Need to know if all the compilation flags are correct.

                              Oh, they are not printing the build commands in Qwt :-( Don't they have some verbose mode or something?

                              If yes, please use it and paste the output here. If no, then please paste the beginning of Makefile that is produced - the section where all compilers and flags are set up.

                                  It still does not list the compiler anywhere... look deeper :-) I'm basically trying to verify whether qmake is building for cross-compilation here or not. Because it should.

                                  Look for CC = or CXX = or something.

                                      Ooops I misunderstood :-) I thought you had errors when compiling Qwt, but now I see you have them when compiling your project. OK.

                                      Compiler setup looks OK.

                                      So you have everything correctly cross-compiled but still it complains about:

                                      /home/user/raspi_QtBuild/sysroot/usr/lib/arm-linux-gnueabihf/libQt5OpenGL.so.5: undefined reference to `operator delete(void*, unsigned int)@CXXABI_1.3.9'
                                      
                                      /home/user/raspi_QtBuild/sysroot/usr/lib/arm-linux-gnueabihf/libQt5OpenGL.so.5: undefined reference to `qTriangulate(QVectorPath const&, QTransform const&, double)@Qt_5_PRIVATE_API'
                                      

                                      Hm :-/ I'm out of ideas to be honest. Looks like Qt has disabled some part of the code, or there is ABI mismatch but both these possibilities seem weird.

                                        Yeah,everything correctly cross-compiled but still it complains OpenGL issue.
                                        So,next what How shall I proceed ?
                                        Any alternate solution for this bug.

                                          Hi,

                                          Might be a silly question but are you sure you are using the same Qt version of building your application that was used to build Qwt ?
