No matching member function for call to 'draw'

[blueoyster]

New to c++ and sfml,
Tried to implement my circle into a separate header and class file.
.draw() doesnt accept that my circle.shape is a drawable.
tho It seems to work with sf::RectangleShape.
I did the almost exact same wtith RectShape and that draws it no problem.

header file ; https://pastebin.com/n7enWda9

circle class: https://pastebin.com/Pq0cAXfn

main file (demo, essentially) : https://pastebin.com/mdDULJfQ

What's the full/complete error?

It errors within the SFML headers. Hmm.

What's your version of MinGW that you're using?

[blueoyster]

gcc (MinGW.org GCC-6.3.0-1) 6.3.0

[eXpl0it3r]

Yeah that's not a compatible compiler. For SFML 3 you need at least GCC 9.

Highly recommend to not use MinGW.org, that hasn't been updated in a decade or so.
The best source for GCC on Windows is either WinLibs or MSYS2.

(The most recommended compiler on Windows is just MSVC and you can't go wrong with Visual Studio.)
