解決Cocos2d-x3.0、3.1 "_opendir$INODE64"symbol(s) not found錯誤，cocos2dx3.0

升級系統和XCode後，在IOS8上編譯之前的項目會報如下錯誤：

Undefined symbols for architecture x86_64:  "_opendir$INODE64", referenced from:      _OPENSSL_DIR_read in libcocos2dx iOS.a(o_dir.o)  "_readdir$INODE64", referenced from:      _OPENSSL_DIR_read in libcocos2dx iOS.a(o_dir.o)ld: symbol(s) not found for architecture x86_64clang: error: linker command failed with exit code 1 (use -v to see invocation)

原來蘋果公司打算自己整一套OPenGL的東西，所有，有些東西需要根據IOS平台來加入它的東西。這個問題的解決方案如下：

在工程目錄下cocos/platform/CCImage.cpp添加如下代碼：

#if defined (__unix) || (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)#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#endif
