Crash while creating IBM ImqQueueManager class object

Question

I am creating an object of ImqQueueManager class like this

ImqQueueManager mqManager;

Default constructor is getting called which is default initializing an object of ImqObject class. Which is further leading to the crash. Here is the call stack

(gdb) bt full

IBM MQ version 7.5 is installed on this 64 bit Linux machine. Same code is working fine on another machine having the same IBM MQ version installed on that.

Can someone please help me to figure out what could be the reason behind this?

Answer 1

IBM MQ version 7.5 is installed on this 64 bit Linux machine.

You are using a release of IBM MQ that is long out of support. See here for a list of IBM MQ End of Service Dates.

Secondly, you should be showing us your code (update your post) because otherwise we will just be guessing.

Here's a fully functioning C++ that will connect to a remote queue manager and put a message to a queue.

/*
 * Program Name
 *  MQTest31.cpp
 *
 * Description
 * Test program to connect to a queue manager using MQCONNX and MQCSP
 * and then put a message from a queue.
 *
 * Sample Command Line Parameters
 *   QMgrName ChlName hostname(port) QName
 *
 * Where
 *    QMgrName is the queue manager name
 *    ChlName is the name of the channel to be used
 *    hostname(port) is the hostname and port number
 *    QName is the queue name
 * i.e.
 *    MQTest31.exe MQWT1 TEST.CHL 127.0.0.1(1415) TEST.Q1
