c++ - 警告:std::binary_function::binary_function() 在静态库 "*.a"中具有不同的可见性(默认)

Question

我在静态库 .a 中定义了一个 std::map，就像这样

//////////////////////////////////////
#import <map>
class CCImage;
class ImageArray{
 std::map<int,CCImage*> mapCCImages;
private:
 int imagesLength;

public:
 ImageArray();
 ~ImageArray();
 int getImageLen();
 bool addCCImage(int key,CCImage * texture,bool replace = true);
 CCImage *getCCImage(int key);
 bool deleteCCImage(int key);
 void releaseResource();
};
/////////////////////////////////////////

我将它作为静态库编译到我的 xcode 项目中，因此将它作为“*.a”导入到项目中但是当我使用如下的另一个定义时:

#include <map>
using namespace std;

struct UseGoodStruct{
 short GoodID;
 Byte GDirection;
};

typedef  map<int,UseGoodStruct *>  GOODSMAP;

and then when I define another variable 

GOODSMAP m_thirdLayer;

xcode 像下面这样警告我:

ld: warning: std::binary_function<int, int, bool>::binary_function()has different visibility (default) in /Users/Vincent/Library/Application Support/QQ/FileRecv/test/libMotion-Debug.a(ImageArray.o) and (hidden) in /Users/Vincent/Library/Application Support/FileRecv/test/build/test.build/Debug-iphonesimulator/test.build/Objects-normal/i386/GeneralDataManage.o

我该如何解决这个问题？谢谢。

尝试在第一个 header 中包含而不是导入。
