Ubuntu 19 GTK compilation problems

[Bitblazer]

Installing and compilation on earlier Ubuntu versions works up to 18, but i cant get purebasic 5.71 x64 to compile a gtk version of my binary linux installer.

This is the linking error i get from the PB 5.71 x64 IDE:



Any ideas how to fix this?
Or is it basically hopeless due to outdated libraries? See this GTK+ 2 Reference for gtk_label_parse_uline ()

ps: The QT version compilation works fine with ubuntu19.
