i made my own lib from a project i want to use in the future and it was giving me a bunch of undefined refs so i made it a dll instead of a static lib and now it only gives me this error
obj\Release\ScriptConsole.o:ScriptConsole.cpp:(.text$_ZN3gui6ButtonD1Ev[gui::Button::~Button()]+0xe): undefined reference to `vtable for gui::Button'
collect2: ld returned 1 exit status
here is the Button class
