"undefined reference to `vtable for"

Hello,

I have several problems when compiling:

Run all the commands in the README.md in the same order, in different Linux distributions (CentOS, Ubuntu 16.04, ArchLinux, Windows - fulfilling all the requirements of versions) always throws the same problem.

Also try to generate the .pro with qmake -project but it does not work, am I doing something wrong?

It seems to me that you are not generating the *moc _ .cpp correctly, can you share or upload the .pro to the repository?

Do you need me to upload some log?

Greetings.
