Unknown protocol: tcp
Hi,
I want to start my simple C++ program (see below) that tries to open a
connection and get following output:
open connection
Unknown protocol: tcp (qpid/client/Connector.cpp:52)
I used static libraries with following link settings:
-static -lqpidclient -static -lqpidcommon -lm -lrt -ldl -luuid -lpthread
-lboost_filesystem -lboost_program_options
My environment is:
- CentOS 5.5 /x86_64
- gcc/g++ 4.1.2
- qpid 0.8
What is wrong here?
Regards,
Grzegorz
#include <qpid/client/Connection.h>
#include <qpid/client/Session.h>
#include <iostream>
using namespace qpid::client;
using namespace std;
int main(int ragc, char** argv) {
Connection connection;
try {
cout << "open connection" << endl;
connection.open("127.0.0.1", 5672);
cout << "new session" << endl;
Session session = connection.newSession();
cout << "close connection" << endl;
connection.close();
} catch (const std::exception& ex) {
cerr << ex.what() << endl;
}
}

Hi,
you are right, the problem disappears when I use dynamic libraries.
Unfortunately for our project I must use static libraries.
Is there some specific order for the libraries required if I want build
own C++ client application?
Is there another way to ensure that the protocol registration is done at
proper time (e.g. I invoke some special method/function before I try to
open a connection)?
Regards,
Grzegorz

My guess would be that the static linking is the issue. The protocol
registration relies on static initialisers at present and the static
linking may result in the wrong order of execution.
Are you able to link dynamically to verify that theory?
