      Hi,
      I'm have a yocto build(fsl-image-gui) running on my imx6 sabre sd board and noeẃ I want to try QT5 on it.
      I'm using the cross compiler from yocto:
      @
      ./configure -opensource -confirm-license -make libs -make demos -make examples -device imx6 -device-option CROSS_COMPILE=/home/masa1/sabre/yocto/build/tmp/sysroots/x86_64-linux/usr/bin/armv7a-vfp-neon-poky-linux-gnueabi/arm-poky-linux-gnueabi- -sysroot /home/masa1/sabre/yocto/build/tmp/sysroots/imx6qsabresd -no-gcc-sysroot -prefix /usr/local/Qt5-yocto-imx6 -opengl es2 -v -no-pch
      @
      I run in to the following problem:

      anyone got any clues?

        I have exactly the same problem, with a ptxdist/Oselas toolchain :

          I had this problem too. I modified "eglvivante.h" header under the sysroot and got it working. The "issue" here is that the #ifdef values in that header files are not set appropriately when you compile Qt with XCB support and you end up with inappropriate egl defines. In that file delete all but the X11 support (you can see quite clear main level #ifdef structure in the file).

            hi ,

            i have a samme problem can anyone help me with this...
            ./configure -opensource -confirm-license -no-opengl -opengl es2 -device linux-imx6-g++ -v -device-option CROSS_COMPILE=/home/giri/fsl-community-bsp/build/tmp/sysroots/i686-linux/usr/bin/cortexa9hf-vfp-neon-poky-linux-gnueabi/arm-poky-linux-gnueabi- -sysroot /home/giri/fsl-community-bsp/build/tmp/sysroots/imx6qsabresd -no-gcc-sysroot -prefix /usr/local/qt5 -optimized-qmake -reduce-relocations -reduce-exports -make libs -no-pch -lz -qt-xcb

            i am getting error saying this what changes i have to do ...

            The OpenGL ES 2.0 functionality test failed!
            You might need to modify the include and library search paths by editing
            QMAKE_INCDIR_OPENGL_ES2, QMAKE_LIBDIR_OPENGL_ES2 and QMAKE_LIBS_OPENGL_ES2 in
            /home/giri/qt5/qtbase/mkspecs/devices/linux-imx6-g++.

              @juhvu Thanks for this post. Now, I am able to compile build for imx6 sabreauto yocto build. But once build was created I am not able to boot. Kernel crashed with following error:
