这是我第一次在 Stackoverflow 上提问。我的问题是当我尝试运行此代码时收到此消息：

} while(0)

 #endif /* __NCTUNS_object_h__ */

在 Object.cc 中

void Set_KeyPair()
{
unsigned long int keyLength = 10;
//static KeyPair ADD(RSA::GenerateKeyPair(keyLength));
NslObject::newKeyPair  (RSA::GenerateKeyPair(keyLength));

//NslObject::KeyPtr
//NslObject::newKeyPair;
}

所以，我的问题是当编译器开始编译时，它会停在这段代码上：

NslObject::newKeyPair  (RSA::GenerateKeyPair(keyLength));

出现的消息是：

Error:
object.cc: In function ‘void Set_KeyPair()’:
object.cc:53: error: no match for call to ‘(KeyPair) (KeyPair&)’

那么，我如何将生成的密钥对类值分配给 NslObject::newKeyPair。

提前高度感谢您的帮助，谢谢。

如果要为其分配新值，则需要使用赋值：

NslObject::newKeyPair = RSA::GenerateKeyPair(keyLength);

您的代码尝试像调用函数一样调用它，但不起作用，因为它不是仿函数。

（此外，您不应该为包含防护使用保留名称。）
