Question

我正在尝试将c ++项目libsnark包装到golang中。我收到以下警告，

SWIG:1: Warning 125: Use of the include path to find the input file is deprecated and will not work with ccache. Please include the path when specifying the input file.
./go_wrapper/swig/../../libsnark/libsnark/gadgetlib2/variable.hpp:320: Warning 401: Nothing known about base class 'VariableArrayContents'. Ignored.
./go_wrapper/swig/../../libsnark/libsnark/gadgetlib2/variable.hpp:332: Warning 315: Nothing known about 'VariableArrayContents::operator []'.
./go_wrapper/swig/../../libsnark/libsnark/gadgetlib2/variable.hpp:333: Warning 315: Nothing known about 'VariableArrayContents::at'.

这是c ++代码段

class Variable {
   /**
    * @brief allocates the variable
    */
public:
    explicit Variable(const ::std::string& name = "");
    virtual ~Variable();
    ...
}; // class Variable

typedef ::std::vector<Variable> VariableArrayContents;

class VariableArray : public VariableArrayContents {
   public:
    using VariableArrayContents::operator[];
    using VariableArrayContents::at;
    using VariableArrayContents::push_back;
    using VariableArrayContents::size;

   ... 
}

这是我的swig文件

%module gadgetlib2

%include <typemaps.i>
%include "std_vector.i"
%include "std_string.i"


%ignore VariableArrayContents;
typedef std::vector<Variable> VariableArrayContents;
%{
typedef std::vector<Variable> VariableArrayContents;
%}
namespace std {
   %template(StringVector) vector<string>;
   %template(VariableArrayContentsVector) vector<Variable>;
   // Use this, got the same result 
   // %template(VariableArrayContentsVector) vector<Variable>;
}


%include "../../libsnark/libsnark/gadgetlib2/variable.hpp"
%include "../../libsnark/libsnark/gadgetlib2/variable_operators.hpp"
%include "../../libsnark/libsnark/gadgetlib2/protoboard.hpp"
%include "../../libsnark/libsnark/gadgetlib2/pp.hpp"
...

我是SWIG的新手，不太了解如何编写这种复杂的脚本。 c ++项目是第三方项目，我们不打算涉及它。

如果使用自定义模板类，则对基类一无所知
