错误：没有匹配函数调用'PSTUNClient :: PSTUNClient

Question

下面的代码总是抛出相同的错误，它似乎在ubuntu中工作，但不在fedora/centos中。

2945 void H323EndPoint::SetSTUNServer(const PString & server) 
2946 { 
2947 natMethods->RemoveMethod("STUN"); 
2948 delete stun; 
2949 
2950 if (server.IsEmpty()) 
2951  stun = NULL; 
2952 else { 
2953  stun = new PSTUNClient(server, 
2954       GetUDPPortBase(), GetUDPPortMax(), 
2955       GetRtpIpPortBase(), GetRtpIpPortMax()); 
2956 
2957  natMethods->AddMethod(stun); 
2958 
2959  PTRACE(2, "H323\tSTUN server \"" << server 
       << "\" replies " << stun->GetNatTypeName()); 
2960 
2961   STUNNatType((int)stun->GetNatType()); 
2962 } 
2963 } 
2964 
2965 #endif // P_STUN 

步骤尝试：

Answer 1

编译器告诉你它找不到的PSTUNClient类的构造函数与原型PSTUNClient::PSTUNClient(const PString&, WORD, WORD, WORD, WORD)。

这些都是相关的线路中的错误输出：

h323ep.cxx:2955:65: error: no matching function for call to ‘PSTUNClient::PSTUNClient(const PString&, WORD, WORD, WORD, WORD)’ 
/root/ptlib/include/ptclib/pstun.h:441:5: note: candidates are: PSTUNClient::PSTUNClient() 
/root/ptlib/include/ptclib/pstun.h:438:1: note:     PSTUNClient::PSTUNClient(const PSTUNClient&) 

在代码中，这条线：

stun = new PSTUNClient(server, 
         GetUDPPortBase(), GetUDPPortMax(), 
         GetRtpIpPortBase(), GetRtpIpPortMax()); 

...是一个导致错误。

您可能试图使用不存在的构造函数。编译器暗示您使用PSTUNClient::PSTUNClient()代替。

即

stun = new PSTUNClient(); 

如果在编译你的Ubuntu构建但不Fedora的，问自己，如果你使用的PSTUN库相同版本的两个版本。
