    Did you already saw this wiki page about the imx6 ?

    It might give you some additional clues

      @SGaist Yes I did. It's supposed to be simple, just setting the QPA plugin platform u want to use and it should work. But not in my case :(

      Hmm, I think I found the problem.

      This is how I deployed my application:

      .
      ├── egldeviceintegrations
      │   └── libqeglfs-viv-integration.so
      ├── helloworld
      ├── libEGL.so.1
      ├── libGAL.so
      ├── libGLESv2.so.2
      ├── libpng16.so.16
      ├── libQt5Core.so.5
      ├── libQt5EglDeviceIntegration.so.5
      ├── libQt5Gui.so.5
      ├── libQt5Widgets.so.5
      ├── libVSC.so
      └── platforms
          ├── libqeglfs.so
          ├── libqminimalegl.so
          ├── libqminimal.so
          └── libqoffscreen.so
      

      Having built it setting rpath:

      unix:{
          QMAKE_LFLAGS_RPATH=
          QMAKE_LFLAGS += "-Wl,-rpath,\'\$$ORIGIN\'"
      }
      
      # ldd helloworld 
      libQt5Widgets.so.5 => /home/root/helloworld/libQt5Widgets.so.5 (0x769e9000)
      libQt5Gui.so.5 => /home/root/helloworld/libQt5Gui.so.5 (0x76572000)
      libQt5Core.so.5 => /home/root/helloworld/libQt5Core.so.5 (0x76054000)
      libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x75f13000)
      libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x75ee7000)
      libc.so.6 => /lib/libc.so.6 (0x75dad000)
      libpthread.so.0 => /lib/libpthread.so.0 (0x75d84000)
      libGLESv2.so.2 => /home/root/helloworld/libGLESv2.so.2 (0x75c8b000)
      libm.so.6 => /lib/libm.so.6 (0x75c0d000)
      libz.so.1 => /lib/libz.so.1 (0x75beb000)
      libpng16.so.16 => /home/root/helloworld/libpng16.so.16 (0x75bb3000)
      libdl.so.2 => /lib/libdl.so.2 (0x75ba0000)
      librt.so.1 => /lib/librt.so.1 (0x75b89000)
      /lib/ld-linux-armhf.so.3 (0x76ed7000)
      libGAL.so => /home/root/helloworld/libGAL.so (0x75a8d000)
      libEGL.so.1 => /home/root/helloworld/libEGL.so.1 (0x75a6d000)
      libVSC.so => /home/root/helloworld/libVSC.so (0x759ab000)
      

      So far so good.

      But then I checked the platform plugins dependencies:

      # ldd libqeglfs.so 
      ldd: warning: you do not have execution permission for `./libqeglfs.so`
      libQt5EglDeviceIntegration.so.5 => not found
      libQt5Gui.so.5 => not found
      libQt5Core.so.5 => not found
      libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x76e27000)
      libc.so.6 => /lib/libc.so.6 (0x76ced000)
      libm.so.6 => /lib/libm.so.6 (0x76c6f000)
      /lib/ld-linux-armhf.so.3 (0x54ac5000)
      libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x76c43000)
      
      

      ldd libqeglfs-viv-integration.so shows the same.

      Could be that the problem? How I fix it?

      Update:

      I tried the first approach of deploying, putting libs and plugins in /usr/lib.
      libqeglfs.so and libqeglfs-viv-integration.so now can find their dependencies, but the error persists.

        Solved. I don't know how exactly, because I tried many things altogether, so I will try to find what was the real problem. It's very probable because of the missing touchscreen driver.

        Update:

        At first I solved it unintentionally installing qtbase-examples (I was expecting there would be binaries ready to run, but it was source code) and the package manager installed the needed dependencies too. Then I remove it and discovered what dependencies were these that made my helloworld to work:

        kernel-module-imx-gpu-viv
        libgles2-mx6
        libegl-mx6

          @aV_V hi,i have the same problem ,You remove
          kernel-module-imx-gpu-viv
          libgles2-mx6
          libegl-mx6

          ,and then work,Please how to remove? use "opkg remove"?

            @hflw No no, I dont remove them. I added those missing packages. Actually, this package: kernel-module-imx-gpu-viv, which is the gpu driver, it wasn't missing, I had it as a built-in module. So check ur kernel configuration and make sure u have enabled the gpu driver.
            Then u need to have installed the EGL libraries compiled for ur platform. On my case are libgles2-mx6 and libegl-mx6.

            Tell me more about ur platform and what Yocto setup are u using and I could help u better if that wasn't enough.

            Regards.

              the above,qt program untitled is based on widget and qmlDemo based on qml.

              I try to build the Yocto Krogoth,and the error is the same.the link of post is:

              Qt5.8 for arm:Could not open egl display

              about the kernel configuration,I think the kernel is OK,because I had successful run the qt5.3(platform eglfs) program build on Yocto Dizzy,I checked the kernel cfg MXC_GPU is y

              so How to check step by step?I am confused.Thanks in advance!!!

                the above,qt program untitled is based on widget and qmlDemo based on qml.

                I try to build the Yocto Krogoth,and the error is the same.the link of post is:

                Qt5.8 for arm:Could not open egl display

                about the kernel configuration,I think the kernel is OK,because I had successful run the qt5.3(platform eglfs) program build on Yocto Dizzy,I checked the kernel cfg MXC_GPU is y

                so How to check step by step?I am confused.Thanks in advance!!!

                @hflw Just use menuconfig and search for vivante. If you have set CONFIG_MXC_GPU_VIV then is OK.
                Try to rebuild ur yocto image adding these packages:

                libgal-mx6 \
                libegl-mx6 \
                libvsc-mx6 \
                libglslc-mx6 \
                libgles2-mx6 \
                

                And don't forget to add opengl distro feature (on local.conf)

                DISTRO_FEATURES_append = " opengl"
                

                Is your yocto image console only? If so, do also:

                DISTRO_FEATURES_remove = "x11 wayland"
                

                Btw, that linux kernel is quite old, I don't know if that could be the main problem.

                  @aV_V ,I add the below config on local.conf

                  
                  DISTRO_FEATURES_remove = "x11 wayland"
                  
                  DISTRO_FEATURES_append = " opengl"
                  
                  IMAGE_INSTALL_append = " \
                          libgal-mx6 \
                          libegl-mx6 \

                  "
                  

                  But the error still exists,So I decide to update kernel to Version 3.14(jethro used).

                      @aV_V hi,I have updated the kernel to Version 3.14,But the error still exists.

                      Can u show me your kernel .config file? and what is your kernel Version?
