      Hi All,

      I was using QSystemDeviceInfo to get IMEI from my phone on qt4, now I'm switching to qt5, so as I read I need QDeviceInfo from add-on module https://qt.gitorious.org/qt/qtsystems.

      I have cloned this with git and compiled/installed using gcc qmake, it went fine.

      However, I can't do it with android qmake, it fails when I want to install this.
      So my app is not compiling, I have copied include files into
      5.3/android_armv7/include/QtSystemInfo/
      So I can include QDeviceInfo in project files, but obviously application fails during linking procedure with:
      error: undefined reference to 'QDeviceInfo::QDeviceInfo(QObject*)

      Below is what I'm doing to compile QtSystemInfo for android, qt 5.3, what am I doing wrong ?

      cd Qt/5.3/Src
      franki@franki:~/Qt/5.3/Src$ git clone git://qt.gitorious.org/qt/qtsystems.git
      Cloning into 'qtsystems'...

      mkdir: can't create dir `/libs': Access denied
      make: *** [install_target] Error 1
      franki@franki:~/Qt/5.3/Src/qtsystems$

      I know that I'm doing this not as a root, but installing libqtsystems.so in my Linux /libs directory won't solve my android problem?

      best regards
      Franki

        Hi,

        IIRC, currently it's not implemented for iOS, android and blackberry

          Hi,

          There is a thread on this forum where someone asks about getting IMEI/IMSI from phone and they suggest him using QtSystems module (for Sailfish OS)
          http://qt-project.org/forums/viewthread/33785

          Should I use older qt than 5.3.1 like 5.2 or something ? I think it's quite impossible that this modules is not implemented for android in all qt5 branch ?

          All the best
          Marek

            What OS was your phone running ? And how where you getting the IEMI ?

            SailfishOS is another beast.

            It has just not yet been implemented

              Hi,

              Sorry for late answer.
              I'm running Android 4.1, I'm developing on Linux.
              Getting IMEI is pretty straightforward:
              @
              sysInfo=new QDeviceInfo(this);
              qDebug()<<"NetManager::NetManager imei:"<<sysInfo->imei(0)
              @

              If you know any other way to get unique phone id or sim card id, please tell me.

              best regards
              Marek

                  On windows, I don't know. I'm developing on Linux and it was easy:

                  franki@franki:~/Qt/5.3/Src/qtsystems$ ../../gcc_64/bin/qmake
                  franki@franki:~/Qt/5.3/Src/qtsystems$ make
                  franki@franki:~/Qt/5.3/Src/qtsystems$ make install

                              add a new make “Build Step” and write to the “Make arguments” the install target

                              from the menus, select “Rebuild Project qtserialport”

                                First thing, it's not an example, it's a Qt module, you should rather place it in the same source path as e.g. qtbase.

                                Like I wrote before, it's not yet implemented for Android
