原來蘋果公司打算本身整一套OPenGL的東西，全部，有些東西須要根據IOS平臺來加入它的東西。這個問題的解決方案以下：

在工程目錄下cocos/platform/CCImage.cpp添加以下代碼：

extern "C"
{
#ifndef __ENABLE_COMPATIBILITY_WITH_UNIX_2003__
#define __ENABLE_COMPATIBILITY_WITH_UNIX_2003__
#include <stdio.h>
#include <dirent.h>
    FILE *fopen$UNIX2003( const char *filename, const char *mode )
    {
        return fopen(filename, mode);
    }
    size_t fwrite$UNIX2003( const void *a, size_t b, size_t c, FILE *d )
    {
        return fwrite(a, b, c, d);
    }
    char *strerror$UNIX2003( int errnum )
    {
        return strerror(errnum);
    }
    DIR *opendir$INODE64(const char * a)
    {
        return opendir(a);
    }
    
    struct dirent *readdir$INODE64(DIR *dir)
    {
        return readdir(dir);
    }
#endif
#include "png.h"
#include "tiffio.h"
#include "base/etc1.h"
#include "jpeglib.h"
}
