        which version of Qt are you using? Which platform?

          Hi iam using Qt 5.5 on Ubuntu 14.04 OS.

          I have installed both QtMobility and QStorageInfo and accessed them by including them in the .pro file as well as i have included them in include paths in the project properties, but still iam not able to access them properly.

          And when i saw in the folder QStorageInfo it has only header files, there is no code in them.

          Do i need to install anthing?

            @Ravimettu Can you show your PRO file? It looks like you don't link against QtMobility libraries.

              I have included them by using following lines.

              CONFIG += mobility
              MOBILITY += systeminfo

              INCLUDEPATH += /usr/include/QtMobility
              INCLUDEPATH += /usr/include/QtSystemInfo

                The same code worked in 12.04 with Qt 4.8 but after migrating to Qt 5.5 and ubuntu 14.04 it got this error

                    Hi,

                    as far as I know, QtMobility is not maintained in Qt 5.5; some classes was ported and included in Qt

                    Once your problem is solved don't forget to:

                    • Mark the thread as SOLVED using the Topic Tool menu

                        But i see only header files in the QSystemInfo package and in QtMobility
                        there are no .Cpp files or .so libraries
