[rajasekhar]

Hello everybody,
I am rajasekhar,
I am using qt5.4.1 in ubuntu 15.04,and in past when i was using qt5.3 previouslyin ubuntu 14.04.
There qtserialport was working and qt5serialport5.so also is there in lib files.
But now when i am using 5.4 version of qt in ubuntu 15.04, qtserial port is not working and lib files were also not there in lib files even it was installed by using Ubuntu software centre.
I tried by downloading and doing make as mentioned in qt wiki of qt5serialport5 lib files.but there is no use.
Please help me.
I added QT +=serialport to project file.

Something's not clear: are you using your distribution's Qt or building Qt yourself ?
