Hi and welcome to devnet,

which version of Qt are you using? Which platform?

No one has a crystal ball so you have to provide more information if you want help

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.

[Ravimettu]

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

[Ravimettu]

I have installed Qt in opt. Is it ok? or i should install it in /usr/share

Hi,

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

[Ravimettu]

yes i agree

[Ravimettu]

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