duplicate symbols for architecture i386

ld: 20 duplicate symbols for architecture i386

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Mac 下cocos2d-x 2.2.1 游戏开发 xcode

被这个问题困扰老半天,后来理清原因是工程引入文件重复导致.

引入别人工程,导入classes,resources .

编译后报错.

看上面的错误详细描述:

在其中把我们想要的挑出来,就是红字部分等等一些关键字.

在xcode中工程目录查找.我们会看到重复的.h和.cpp .

把其中一对删除.重新编译.ok!
