Please refer to this link How to install Qt version 4.8.1 in Kubuntu 14.04.

I have run 

./configure
make
sudo make install

Where is .deb file created after run the command sudo make install in qt 4.8 installation process so that I can complete my QT 4.8 installation? I am using Ubuntu Mate OS.

I can't understand these three lines as below in the above link:

  1. This will make a .deb of the source you can install as a normal application via apt
  2. sudo dpkg -i path/to/output.deb
  3. Change path/to/output.deb to the path of the created .deb file.

I can't find the "path/to/output.deb" of created .deb file.

Please help...

    sudo make install usually compiles source into a binary; the output being a binary executable - not a .deb file. View the make file itself to see what it does. Your provided link does something different to what you did. (it installs the binary itself without using deb/dpkg/apt/..) – guiverc Jul 17 '19 at 05:29
  • So according to you @guiverc, after run the commands - > ./configure - > make - > sudo make install -------- Complete QT will be installed? – Mehta Jul 17 '19 at 05:43

    make install is different to checkinstall was my point; but what is built depends on the recipe in the makefile which I have not looked at. Your line in the question "sudo make install (same as sudo checkinstall)" seems to equate make install with checkinstall which is not valid. – guiverc Jul 17 '19 at 05:58
  • okay... i have run the command "sudo make install". what should i do now???? – Mehta Jul 17 '19 at 06:00
  • Welcome to [ubuntu.se]! You seem to have chosen the difficult way… Is there any reason why you can’t simply install libqt4* or qt4-default from Ubuntu repositories? The question you linked refers to Ubuntu [tag:14.04] which is outdated. – Melebius Jul 17 '19 at 06:52
  • ok thanx @Melebius – Mehta Jul 17 '19 at 08:36

    @Melebius I think it's not a duplicate. Certainly not of that one. – Kulfy Jul 18 '19 at 11:03
  • @Kulfy Well, this and the target question contain unrelated requirements but they both result in installing Qt 4 using APT. And the target question has a sensible title at least… However, since this question has got a specific answer, I’m retracting my close vote. – Melebius Jul 19 '19 at 05:41
  • @Melebius Yeah but if OP really followed the answer on the question they linked and wrote checkinstall, it would be a generic question with Qt as an example. But as @guiverc pointed, there's some uncertainty in the question. – Kulfy Jul 20 '19 at 07:46

It's not necessary to compile Qt4 from source because Qt 4.8 is provided by the qt4-default package in all currently supported versions of Ubuntu. To install it open the terminal and type:

sudo apt install qt4-default

After you have installed qt4-default you can run the following command to list other available Qt4 packages:

apt search qt4-*
