    Goodmorning,
    I've built a working image and toolchain for raspberrypio-wifi starting from b2qt distro.
    I could modify the b2qt-embedded-qt5-image.bb recipe as follow for having qtcharts but it doesn't work with qtgamepad. More precisely, it doesn't warn any error or mistake but inside the toolchain path there is no trace of qtgamepad.
    Has anyone faced this problem?
    Thank you.

    IMAGE_INSTALL += "qtcharts qtgamepad"

      Hello to all,
      After some more time, I succeeded to add qtgamepad. Basically, instead of modifying the image recipe b2qt-embedded-qt5-image.bb, I had to change the recipe contained in packagegrup packagegroup-b2qt-embedded-qt5-toolchain-target.bb.

      RDEPENDS_${PN} += " \
          ${MACHINE_EXTRA_INSTALL_SDK} \
          packagegroup-core-standalone-sdk-target \
          \
          .....
          qtgamepad-dev \
          "
      

      I believe that I can do this change in image recipe b2qt-embedded-qt5-image.bb using MACHINE_EXTRA_INSTALL_SDK +=qtgamepad-dev, not test though.

        Hi,

        I haven't used Boot2Qt yet but did you check that you have all dependencies required to build the module ?

          Hello StGaist,
          regarding the dependencies, I tried adding the ones indicated in the following link, in IMAGE_INSTALL but unsuccessfully.
          https://layers.openembedded.org/layerindex/recipe/59814/
          In toolchain path inside Qt3DInput, regarding qtgamepad, there is only the qgamepadinput_p.h, shown below. Don't know if this information can help.

            Qt3D is not related to QtGamepad.

            Did you set sdl2 in PACKAGECONFIG ?

              Hello @SGaist,
              I tried to add PACKAGECONFIG += "sdl2", it compiles but I cannot find qtgamepad cross-compiled. Reading on the net, qtgamepad is a new add-on library that comes version 5.12. My b2qt version is 5.11. Is that a possible reason why I cannot find it?
              Thank you for your help.

                The module itself is already usable, it's in tech preview but you can use it with Qt 5.11

                  Hello @SGaist ,
                  if that so, I've run out any ideas. Instead of Qtgamepad, I can use simple linux GPIOs, but I was curious to try gamepad. Maybe in future b2qt version, they'll add qgamepad as default, so I'll see what I'm doing wrong.
                  Thank you for you time.
