我在包装包含 std::complex 值的 4 维 std::vector 时遇到问题。它基本上是一个具有 2 个自由度的矩阵，因此是 4 维的。由于矩阵大小因这些而异，因此使用嵌套向量对我来说似乎是明智的（如果我错了，请纠正我）。
所以数据类型看起来像
std::vector<std::vector<std::vector< std::vector<gr_complex > > > > my4dimvec;
为了使它可以在 python 中访问，我创建了以下 .i 文件：
/* -*- c++ -*- */
#define DRMRX_API
%include "gnuradio.i" // the common stuff
%{
#include "drmrx_conf.h"
#include "drmrx_params.h"
%}
//load generated python docstrings
%include "drmrx_swig_doc.i"
namespace std {
%template() vector< std::vector< std::vector< std::vector<int> > > >;
%template() std::vector< std::vector< std::vector< std::vector< gr_complex > > > > ;
};
%include "drmrx_conf.h"
%include "drmrx_params.h"
gr_complex 是在 gnuradio.i 中完成的类型定义的 std::complex。顺便说一句，4 维 int-vector 工作得很好。
我得到的编译错误是

任何想法可能是什么问题？
