Why am I getting this error: undefined reference to `qt_version_tag '"?

Question

I am using Qt 5.7 on an Ubuntu 16 LTS machine.

I get this error:

(. qtversion [qt_version_tag] + 0x0): - 1: error: undefined reference to `qt_version_tag '

This error only occurs when I use the SDL libraries.

I understand that this is an old thread, but you can avoid it by specifying QT_NO_VERSION_TAGGING; that is, passing the option:

-DQT_NO_VERSION_TAGGING

in gcc.
