Hey I am having some problem with my code I just cant figure it out.
I keep getting undefined reference to `Object::LoadTexture(char const*)' and i cant seem to figure it out.

The Full Error

/tmp/cc81gq9q.o: In function `Object::draw()':
Object.cpp:(.text+0xd4): undefined reference to `Object::LoadTexture(char const*)'
collect2: ld returned 1 exit status


Here is my code

}


Oh and it my compiling i do this (g++ Main.cpp Player.cpp Object.cpp -o Game -lGL -lglfw -lBox2D)

thanks for the help
