Компиляция OmniORB4 с помощью Clang ++

Я изучаю Corba с OmniORB и пытаюсь скомпилировать простой пример программы, но она не работает. К сожалению, действительно сложно найти информацию, как это сделать.

То, что я делаю, выглядит так:

1. Я сделал простой интерфейсный файл в idl каталог

   interface IssueAlert {
   string sendAlert(in string alert);
   };
   

2. Скомпилируйте его, используя omniidl -bcxx -Wbexamples echo.idl

3. Я получаю файлы результатов и с помощью примеров сделал этот код в качестве серверного приложения.

   #include "idl/echo.hh"#include <iostream>
   using namespace std;class IssueAlert_i : public POA_IssueAlert {
   public:
   IssueAlert_i();
   virtual ~IssueAlert_i();
   char* sendAlert(const char* alert);
   };
   
   IssueAlert_i::IssueAlert_i(){}
   IssueAlert_i::~IssueAlert_i(){}
   
   char* IssueAlert_i::sendAlert(const char* alert){
   cout << "Upcall: " << alert << endl;
   return CORBA::string_dup(alert);
   }
   
   //////////////////////////////////////////////////////////////////////
   
   int main(int argc, char** argv){
   try {
   CORBA::ORB_var          orb = CORBA::ORB_init(argc, argv);
   CORBA::Object_var       obj = orb->resolve_initial_references("RootPOA");
   PortableServer::POA_var poa = PortableServer::POA::_narrow(obj);
   
   PortableServer::Servant_var<IssueAlert_i> issue = new
   IssueAlert_i();
   
   PortableServer::ObjectId_var issue_id = poa->activate_object(issue);
   
   // Obtain a reference to the object, and print it out as a
   // stringified IOR.
   obj = issue->_this();
   CORBA::String_var sior(orb->object_to_string(obj));
   cout << sior << endl;
   
   PortableServer::POAManager_var pman = poa->the_POAManager();
   pman->activate();
   
   // Block until the ORB is shut down.
   orb->run();
   }catch (CORBA::SystemException& ex) {
   cerr << "Caught CORBA::" << ex._name() << endl;
   }catch (CORBA::Exception& ex) {
   cerr << "Caught CORBA::Exception: " << ex._name() << endl;
   }
   return 0;
   }
   

4. Для компиляции я использую команду:

   clang++ -std=c++17 -Wall -Wextra -Wnarrowing -Wsign-conversion -lomniORB4 -lomnithread -lomniDynamic4 servant.cpp -I/usr/include -L/usr/lib64/ -o server
   

Все вещи OmniORB, установленные yum, находятся в /usr/include а также /usr/lib64,
Я получаю эту ошибку:

Может ли кто-нибудь помочь мне с этой компиляцией — к сожалению, окончательный проект, который я хочу сделать, должен использовать C ++ 17, тогда лучше всего будет остаться с этим компилятором.
