/usr/include/opencv2/gpu/gpu.hpp:432:29: error: ‘vector’ does not name a type

I faced a problem while compiling compute_flow.cpp，As follows：
“/usr/include/opencv2/gpu/gpu.hpp:432:29: error: ‘vector’ does not name a type
CV_EXPORTS void merge(const vector& src, GpuMat& dst, Stream& stream = Stream::Null());
^
/usr/include/opencv2/gpu/gpu.hpp:432:35: error: expected ‘,’ or ‘...’ before ‘<’ token
CV_EXPORTS void merge(const vector& src, GpuMat& dst, Stream& stream = Stream::Null());
^
/usr/include/opencv2/gpu/gpu.hpp:438:42: error: ‘vector’ has not been declared
CV_EXPORTS void split(const GpuMat& src, vector& dst, Stream& stream = Stream::Null());
^
/usr/include/opencv2/gpu/gpu.hpp:438:48: error: expected ‘,’ or ‘...’ before ‘<’ token
CV_EXPORTS void split(const GpuMat& src, vector& dst, Stream& stream = Stream::Null());”
The opencv version shown in cmake is 3.2.0.I don't know how to solve the above problem.
