Godot.hpp template issue (conversion error)

I am trying to use my newly compiled shared lib but cant seem to be able to use the Godot.hpp header.
I get the same template error all the time:

line 122 (definition on 105)
no mach converting..

and line 125 (definition on 114)
no mach converting

i have not studies the source of godot but as far as i undestrand this has to do with the conversion when using the = operator on said lines.

i cant seem to find a workaround and really dont wanna have to study all the code.

If anyone has some advice or even temporary fix it would be greatly appreciated!

note: using gcc 9.3 and c++14 standard
