Objective-C++ で Objective-C ヘッダーをインポートするにはどうすればよいですか?

これはヘッダーです：

typedef struct _xmlDoc xmlDoc;
typedef struct _xmlNs xmlNs;
typedef struct _xmlAttr xmlAttr;
typedef struct _xmlNode {
    void* _field1;
    int _field2;
    char* _field3;
    struct xmlNode* _field4;
    struct xmlNode* _field5;
    struct xmlNode* _field6;
    struct xmlNode* _field7;
    struct xmlNode* _field8;
    xmlDoc* _field9;
    xmlNs* _field10;
    char* _field11;
    xmlAttr* _field12;
    xmlNs* _field13;
    void* _field14;
    unsigned short _field15;
    unsigned short _field16;
} xmlNode;

typedef struct _xmlDict xmlDict;
typedef struct _xmlDtd xmlDtd;
struct _xmlDoc {
    void* _field1;
    int _field2;
    char* _field3;
    struct xmlNode* _field4;
    struct xmlNode* _field5;
    struct xmlNode* _field6;
    struct xmlNode* _field7;
    struct xmlNode* _field8;
    struct xmlDoc* _field9;
    int _field10;
    int _field11;
    struct xmlDtd* _field12;
    struct xmlDtd* _field13;
    struct xmlNs* _field14;
    char* _field15;
    char* _field16;
    void* _field17;
    void* _field18;
    char* _field19;
    int _field20;
    struct xmlDict* _field21;
    void* _field22;
    int _field23;
    int _field24;
};

struct _xmlNs {
    struct xmlNs* _field1;
    int _field2;
    char* _field3;
    char* _field4;
    void* _field5;
    struct xmlDoc* _field6;
};

struct _xmlAttr {
    void* _field1;
    int _field2;
    char* _field3;
    struct xmlNode* _field4;
    struct xmlNode* _field5;
    struct xmlNode* _field6;
    struct xmlAttr* _field7;
    struct xmlAttr* _field8;
    struct xmlDoc* _field9;
    struct xmlNs* _field10;
    int _field11;
    void* _field12;
};

struct _xmlDtd;

struct _xmlDict;

typedef struct sqlite3 sqlite3;

typedef struct sqlite3_stmt sqlite3_stmt;

プロジェクトをコンパイルすると、次のエラーがスローされます。

これは、ヘッダーが Objective-C で書かれているためではないでしょうか。

ええ、問題は type の何も定義されていないことですstruct xmlNode。タイプstruct _xmlNodeとタイプxmlNodeがありますが、ありませんstruct xmlNode。のすべてのインスタンスstruct xmlNodeをxmlNodeまたはで置き換えることができますstruct _xmlNode。
