  • 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

  • Hi,

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