@seemar From a quick look at the PPA,
opt-qt57-trustydoesn't exists hence your error. -

@SGaist In this link https://launchpad.net/~beineri/+archive/ubuntu/opt-qt562-trusty, it is
saying to execute Source /opt/qt56/bin/qt56-env.sh. I cant able to find the script in that directory. Can you help me in setting up the environment and than installing the qt5.6.2. -
You should be able to do that once you installed the package.
No I can't further, if I need a specific version of Qt I usually build it myself.

Hi,
Taking a look at the reference platforms here, only 64 bit linux is mentioned.
So you'll have to build Qt yourself if you need to target 32bit distributions.

Help will be appreciated. -

Help will be appreciated.@nitish_linked Well, download the Qt 5.6 source code and build it. How do you know that your version is still 5.5? And how did you build it?

@jsulm Hi, thanks for replying.
My machine previously had Qt5.5, so i decided to upgrade it to Qt5.6.
For that, I followed the following steps :-
1.) Downloaded qt-everywhere-opensource-src-5.9.2
2.) ./configure -prefix $PWD/qtbase -opensource -nomake tests
3.) make -j 4It will be great if you can guide me if i am doing some mistake.

Why are you using Qt 5.9.2 sources if you want to build Qt 5.6 ?
In any case, you should also add
-nomake examples. -

@nitish_linked You forgot to call "make install". And later if you call qmake use absolute path to it to make sure you call qmake from that Qt.

Is there a problem of absolute path of qt ?? -
By calling only
qmakeyou are calling your distribution provided qmake, use the full path if you want to call a specific Qt version. -

Is there a problem of absolute path of qt ??@nitish_linked As @SGaist said use absolute path to your qmake. If you just call qmake the system looks in some predefined locations (like /usr/bin) and in directories PATH is showing to and finds qmake from your distribution.
