Installation of Qt 4.8.7 in Ubuntu 18.04.1 LTS

[die Dauphin]

I am trying to install Qt 4.8.7 from source (https://download.qt.io/archive/qt/4.8/4.8.7/qt-everywhere-opensource-src-4.8.7.tar.gz) in a virtual machine running Ubuntu 18.04.1 LTS

So the commands I follow are:

mkdir Qt
cd Qt
wget https://download.qt.io/archive/qt/4.8/4.8.7/qt-everywhere-opensource-src-4.8.7.tar.gz
tar -xzf qt-everywhere-opensource-src-4.8.7.tar.gz
mv qt-everywhere-opensource-src-4.8.7 Qt-Source
cd Qt-Source
./configure

Then I choose the Open Source Edition, accept the terms of License. After that it displays:

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /usr/local/Trolltech/Qt-4.8.7

So ...

make 

and I have the next error;

Another thing is that in the process of running make, there are a lot of errors like these:

Could you help me? Please

@die-Dauphin What version of OpenSSL is installed on that machine?

Hi and welcome to devnet,

You don't need to do that. Your distribution already provides Qt 4.8.7. You should use that one as it will have proper OpenSSL support directly.
