我有以下代码行:
if(std::binary_search(face_verts.begin(), face_verts.end(), left_right_vert[0]) &&
std::binary_search(face_verts.begin(), face_verts.end(), left_right_vert[1]))
当我编译我的代码时,我收到以下错误:

make: *** [R3Mesh.o] Error 1
我#include <algorithm>
在文件的开头做了,我似乎无法找出错误。以下是函数调用中使用的容器:
vector <R3Point > face_verts;
vector <R3Point > left_right_vert;
谢谢。
