Error in Installing Qt in Ubuntu-mate 18.04
-
@Malathi-K Usually the development files have a
-devsuffix. But my Ubuntu 14.04 here shows:apt-cache search qt5 | grep qt5-default qt5-default - Qt 5 development defaults packageso qt5-default should be a good start.
Also note that Qt 4 is already very old and I would not use it for new development.

@jsulm -I have installed qtbase5-dev as per your suggestion but still I get error.Please check the screenshot.
Also, My kits have no option for Qt5(qt2.png)
Help me in solving this error.
@malathi-k Sorry, but in these tiny screenshots I cannot see anything helpful...
Please show the whole Kit configuration.
Also, there is an yellow exclamation mark on the left side of the Kit name put the cursor over it and see what the popup shows.
Also, do you really want to use Qt4 which is dead since many years already? -

@malathi-k Are you aware that this screenshot is way too small to contain any useful information? In fact it contains less information than your previous screenshots. So, what should I check?
Why don't you make a bigger screenshot?
And did you do what I suggested before - put mouse cursor over the yellow exclamation mark? -

How anyone can work on a 592 x 448 Screen is beyond me. I don't know what the minimal resolution of QtCreator is, but I would bet it higher than that.

Hi @Malathi-K
I'd recommed to use the Qt Online installer. With that you can install latest Qt packages and the QtCreator as well. The installer will automatically install Kits (registers compilers and debuggers) and in addition it will contain the examples and documentation of the selected Qt packages:
