    Hi and welcome to devnet,

    Before diving deeper into this, which distribution are you using ?
    Does it provide Qt ? If so, why not build QGroundControl with it ?

      Hello @SGaist

      in the source and builds section related to QGroundControl, it is recommended to install Qt-5.15.2. I tried the online installer on Jetson NX it didn't work, maybe there is a problem with ARM-arch. So, I tried to build Qt-5.15.2. using the commands in the post.

        Hence my question about the distribution.
        It may already provide Qt 5.15.

        The online installer is built for the x86_64 platform thus you cannot run it on ARM.

          I think that neither Qt nor an ARM build of QGroundControl are provided (i didn't find any).

            That was not my question.

            Which distribution are you using on your Jetson ?

              My jetson has jetpack 6.1 on it. the Qt's version provided by the jetpack is a version earlier than 5.15.2 (i don't recall the exact version) and I didn't find qmake on my jetson.

              So, I tried to build Qt 5.15.2.

                You have to install qmake using the package manager if you want to use the Qt version from your distribution. You will also need to install the dev packages of the Qt modules you will use.

                That said, to build Qt, you should install the build dependencies of the modules you want to build. This can be done using apt.

                  I tried to build QGroundControl using Qt-5.9.1 which comes with the Jetpack. QGroundControl doesn't allow any Qt version less than 5.10 to build it.

                  I installed the required packages form the package manager and successfully built QGroundControl.

                  your help is appreciated.

                    Isn't there a more recent version of JetPack ?

                    One thing to do is to install the builddep of the modules you want to build and then start from scratch.

                      the latest version of Jetpack is 5.0.2/ubuntu20. I currently use Jetpack 4.6.3/Ubuntu18 because remote desktop connection didn't work well for me when i tried the latest version.

                      I tried to build QGroundControl form source again on a fresh jetpack 4.6.3 installation with Qt-5.15.2 and i stumbled upon a new errors, i think there is some problem with the private headers.

                      I got this error when i tried to use make in the build folder in QGroundControl

                      i have no idea what to do here, i tried adding #include <QSslConfiguration> , #include <QSslSocket> and #include <QNetworkRequest> to GoogleMapProvider.cpp but adding those includes didn't do anything.

                        How did you install Qt ?
                        Which packages exactly ?

                        I tested the build on macOS with 5.15.2 as well and it went fine.

                          I installed Qt using the following commands

                          wget http://master.qt.io/archive/qt/5.15/5.15.2/single/qt-everywhere-src-5.15.2.tar.xz
                          tar -xpf qt-everywhere-src-5.15.2.tar.xz
                          cd qt-everywhere-src-5.15.2/
                          ./configure -xcb -skip qtwebengine
                          make -j4
                          sudo make install
                          

                          the problem is no more, apparently you need to build Qt with ssl support . i just installed libssl and built Qt again. Everything works fine now.

                          Thank you.
