No matching function call error when the functions are actually being called

I am currently doing a project for school and for some reason, g++ won’t compile my code properly, saying:

Rectangle.cpp: In constructor ‘Rectangle::Rectangle()’:
Rectangle.cpp:8:22: error: no matching function for call to ‘Line::Line()’

and the build scripts:
Point: g++ -Wall -c Point.cpp -o Point.o
Line: g++ -Wall -c Line.cpp -o Line.o
Rectangle: g++ -Wall -Wextra -c Rectangle.cpp -o Rectangle.o

I did leave out a lot of other unnecessary information so if you need it, my project is here

Thank you in advance and hope you all have a very nice day (or night!)

>Solution :

You are trying to default construct two Lines (width and length) in the Rectangle constructor. Since Line doesn’t have a default constructor you need to use the member initializer list:

Rectangle::Rectangle() : // colon starts the member initializer list
    width(Point(0,4), Point(0,0)),
    length(Point(0,0), Point(8,0))
{}
