有两个库扩展了 EAGLview，我想同时使用它们。如何？
openFrameworks 和 cocos2d 两者都有 EAGLview.h 的包装器，当然您不能同时使用两者。只需将两个库（libcocos2d.a 和 libofxiPhone_iphoneos_Release.a）添加到我的项目中就会出现链接器错误：
ld: duplicate symbol _OBJC_METACLASS_$_ES1Renderer in /Developer/of_007_iphone/apps/cwi007/iTicTacToe/libofxiPhone_iphoneos_Release.a(ES1Renderer.o) and /Developer/of_007_iphone/apps/cwi007/iTicTacToe/libs/libcocos2d.a(ES1Renderer.o) for architecture armv7
collect2: ld returned 1 exit status
Command /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++-4.2 failed with exit code 1
我正在 openFrameworks< 中编写程序的核心< /strong> 因为它很简单并且是 C++。我想用 cocos2d 添加 UI、过渡、菜单等，因为它也很简单，而且看起来很漂亮。
我尝试
#define __OPENFRAMEWORKS__
在一个 .h 文件中尝试，然后将另一个文件包装起来，
#ifndef __OPENFRAMEWORKS__
#endif
认为我可以使用 cocos2d 添加的额外位来“增强”openFrameworks 中的 .h，但随后 openFrameworks不会构建，因为它不再有 EAGLview 的定义。
是否存在使用两个这样的库的最佳实践，这两个库都利用相同的低级功能（在本例中为 CoreAnimation）？我可以编写自己的类来继承它们吗？有没有办法从我的项目中删除 .h 文件之一？
openFrameworks and cocos2d both have a wrapper for EAGLview.h, and of course you can't just use both. Just adding both libraries (libcocos2d.a and libofxiPhone_iphoneos_Release.a) to my project gives a linker error:
ld: duplicate symbol _OBJC_METACLASS_$_ES1Renderer in /Developer/of_007_iphone/apps/cwi007/iTicTacToe/libofxiPhone_iphoneos_Release.a(ES1Renderer.o) and /Developer/of_007_iphone/apps/cwi007/iTicTacToe/libs/libcocos2d.a(ES1Renderer.o) for architecture armv7
collect2: ld returned 1 exit status
Command /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++-4.2 failed with exit code 1
I'm writing the core of my program in openFrameworks because it's easy and C++. I want to put a UI, transitions, menus etc. in with cocos2d because it's also easy and looks nice.
I tried
#define __OPENFRAMEWORKS__
in one .h file, and wrapping the other in
#ifndef __OPENFRAMEWORKS__
#endif
figuring I could "augment" the .h in openFrameworks with the extra bits added in by cocos2d, but then openFrameworks wouldn't build because it no longer had a definition for EAGLview.
Is there a best practice for working with two libraries like this that both tap into the same low-level functionality, in this case CoreAnimation? Can I write my own class that inherits from them both? Is there a way to excise one of the .h files from my project?

尝试包含
cocos2d.h标头，其中EAGLview.h包含在原始 openFrameworks 代码（即ofMain.h）中，反之亦然。Try to include the
cocos2d.hheader whereEAGLview.his included in the original openFrameworks code (i.e.ofMain.h), or vice versa.
