我有以下头文件：gaiageo.h，定义为

#ifndef DOXYGEN_SHOULD_SKIP_THIS
/* stdio.h included for FILE objects. */
#include <stdio.h>
#ifdef DLL_EXPORT
#define GAIAGEO_DECLARE __declspec(dllexport)
#else
#define GAIAGEO_DECLARE extern
#endif
#endif

#ifndef _GAIAGEO_H
#ifndef DOXYGEN_SHOULD_SKIP_THIS
#define _GAIAGEO_H
#endif

#include "gg_const.h"
#include "gg_structs.h"
#include "gg_core.h"
#include "gg_mbr.h"
#include "gg_formats.h"
#include "gg_dynamic.h"
#include "gg_advanced.h"

#endif /* _GAIAGEO_H */

包含的头文件充满了 GAIAGEO_DECLARE，例如 gg_formats.h（这是非常典型的包含头文件）具有以下内容：

/**
\file gg_formats.h

Geometry handling functions: formats
*/

#ifndef _GG_FORMATS_H
#ifndef DOXYGEN_SHOULD_SKIP_THIS
#define _GG_FORMATS_H
#endif

#ifdef __cplusplus
extern "C"
{
#endif

/* function prototypes */

/**
 Test CPU endianness

 \return 0 if big-endian: any other value if little-endian
 */
    GAIAGEO_DECLARE int gaiaEndianArch (void);

/**
 Import an INT-16 value in endian-aware fashion

 \param p endian-dependent representation (input buffer).
 \param little_endian 0 if the input buffer is big-endian: any other value
 for little-endian.
 \param little_endian_arch the value returned by gaiaEndianArch()

 \return the internal SHORT value 

 \sa gaiaEndianArch, gaiaExport16

 \note you are expected to pass an input buffer corresponding to an
 allocation size of (at least) 2 bytes.
 */
    GAIAGEO_DECLARE short gaiaImport16 (const unsigned char *p,
                    int little_endian,
                    int little_endian_arch);
#ifdef __cplusplus
}
#endif

#endif  /* _GG_FORMATS_H */

这是我第一次尝试创建接口文件，想要一些帮助，在线文档让我感到困惑？

我应该为每个标头创建一个接口文件，我应该如何为包含的 gaiageo.h 创建接口？

这应该可以帮助您入门，但很难确切知道您需要什么。

%include <windows.i>使 SWIG 处理像__declspec(dllexport).

默认情况下，SWIG 不会递归包含文件，因此请包含您需要 SWIG 处理的文件。有一个切换到递归，但随后它会处理stdio.h.

%module gaiageo

%{
#include "gaiageo.h"
%}

%include <windows.i>
%include "gaiageo.h"
%include "gg_const.h"
%include "gg_structs.h"
%include "gg_core.h"
%include "gg_mbr.h"
%include "gg_formats.h"
%include "gg_dynamic.h"
%include "gg_advanced.h"

将其保存为gaiageo.i文件并运行类似：

swig -c++ -<target_language> gaiageo.i
