我正在使用OpenGL,我构建并编辑了一个可以与struct Vector3
一起使用的完美工作的Vector3标题,但是当我尝试创建一个Vector3 zero = Vector3(0,0,0)
变量,编译器没有& #39; t由于编译顺序让我构建,所以我从Internet复制了一个新的Vector3库,我收到了这个错误:"Vector3 does not name a type"
。我想是因为编译的顺序,我将分享我得到错误和库的地方。首先,这是我使用http://leetnightshade.com/c-vector3-class的2个文件我只使用了Vector3.cpp和Vector3.h,这个代码是由我制作的,是我得到错误的地方(这是一个名为GameObject.h的main.cpp文件调用的头文件:
#include "Vector3.h"

专注于4行struct GameObject,这是我在Vector3位置得到错误的地方;线。我想我正确地解释了自己。如果你不太了解http://gyazo.com/77189bef5576b047de5271f1b7d2d881,我就制定了一个计划。感谢阅读。
答案 0 :(得分:1)
您链接的Vector3
库使用名称空间_Warp
,因此您应该这样使用它:
_Warp::Vector3 position;
PS:警惕任何使用保留名称作为标识符的第三方库,因为作者可能不知道他们在做什么。 _Warp
是编译器的保留名称(以_
加上大写开头),不应由库或程序代码使用。
