OpenGL을 사용하는 C ++ 프로젝트에 문제가 있습니다. 내 파일 'cube.cpp'에 다음이 있습니다.
point3 r1 = point3(40.0,0.0,-450.0);
point3 r2 = point3(55.0,0.0,-450.0);
point3 r3 = point3(55.0,0.5,-450.0);
point3 r4 = point3(40.0,0.5,-450.0);
point3 r[4];
r[0] = r1;
r[1] = r2;
r[2] = r3;
r[3] = r4;
rails(r);
Point3는 정점을 나타내는 객체입니다. Rails는 3D 레일을 그리는 객체입니다. 문제는 프로젝트를 컴파일하고 싶을 때 다음과 같습니다.
g++ Struct.cpp skybox.cpp rails.cpp cube.cpp -o train
cube.cpp:
In function ‘void display()’:
cube.cpp:296:11: error: conflicting declaration ‘rails r’
rails(r);
^
cube.cpp:291:11: error: ‘r’ has a previous declaration as ‘point3 r [4]’
point3 r[4];
^
친구들에게 물어 보았지만 왜 rails (r) 컴파일을 원하지 않는지 알 수 없었습니다. 이전에 Skybox 클래스를 만들었고 인자에 같은 유형을 가진이 클래스가 올바르게 작동합니다.
누군가 아이디어가 있다면 ...

현재 rails라는 개체 를 만들려고합니다 r.
rails생성자를 호출 할 개체 이름을 추가합니다 . 처럼rails my(r);
