Qt Installed but it does not work

[hix_boz]

Hello all,

I installed Qt 5.15.1 version to my host desktop with Ubuntu 16.04 operating system. When I command "qtcreator", it does not work. When I have commanded "qtcreator.sh" , I got the following messages.

pc@pc-Lenovo-ideapad-510-pc15ISK:~/Qt/Tools/QtCreator/bin$ ./qtcreator
./qtcreator: /lib/x86_64-linux-gnu/libz.so.1: version `ZLIB_1.2.9' not found (required by /home/pc/Qt/Tools/QtCreator/bin/../lib/Qt/lib/libQt6Gui.so.6)

```)

How can I solve this issue? Thanks in advanced.

Install the C/C++ Development Package

In addition to @Gerhard. Be aware that Qt6 Supported platforms states

Linux (Ubuntu 20.04, CentOS 8.1, OpenSuSE 15.1)

so whether you will get Ubuntu 16.04 to work with it is unknown.

Note that although you have installed Qt 5.15.1 your Qt Creator is the latest (6? 7?), and you can see it uses Qt6. If that is a problem in this light you would need to get an older version of Qt Creator which still uses Qt5 rather than Qt6....

Thanks for reply. How can I install C/C++ Development Package? Do I have to use qt online installer again?

Hi,

You should concentrate on what @JonB wrote, your current issue is that your distribution is too old to run that version of Qt Creator. Either install a previous one, the one coming from your distribution or build Qt Creator yourself with Qt 5.
