Web1 Nov 2024 · To create a vector in C++, you first have to include the vector library. You do this by adding the line #include at the top of your file. This line goes after the line #include and any other header files you've included in your program. The std::vector is included in the #include library. WebWhen wrapping a C++ template class containing vectors with SWIG, you may encounter issues with the template instantiation failing to recognize the vector type. One solution is to explicitly instantiate the template class for the desired vector types in the C++ code, and then use SWIG to wrap the instantiated classes.
