c++ - 在 Objective C++ .mm 文件中包含 POCO 头文件会导致 Xcode 6 出现编译错误

Question

如果我在 .mm 文件或 .h 文件中包含任何 POCO 头文件，我会看到以下奇怪的错误。如果我在 .cpp 文件中包含 header ，则项目会成功编译。任何使 POCO 与 Objective C 项目一起运行的帮助或示例代码都将不胜感激。

代码如下:

//File: test.mm

#import "test.h"    
#include "Poco/JSON/Object.h"

@implementation test
-(void)test{
 Poco::JSON::Object obj;
}
@end

这是错误 的截图

Answer 1

好的，错误的原因是POCO头文件与OSX SDK中的头文件之一冲突。 在包含任何 header 之前添加以下行修复了编译问题。

#undef check
