I was trying out bloomberg c++ api example. Got the error below:

Does anyone has idea about the api? What is the connection that it is trying to connect to? Do I need any additional server listening on the port 8194?
In order to use the Bloomberg API SDKs, you need a Bloomberg data feed, which is delivered as part of a Bloomberg subscription product. The API SDK connects to the data feed endpoint using a TCP connection on port 8194 (as you can see), and the example programs assume there is an endpoint on 'localhost' (as there is on any machine with an operating Bloomberg Professional terminal).
You are running this on a Linux machine, and unless you've installed a data feed appliance package on that machine, you don't have an API endpoint on 'localhost'. If you have an API endpoint in your network, you'll need to specify the proper command line arguments to the example program to tell it the IP address (and port number, if non-default) of your API endpoint.
(Also, note that the specific example program you are trying to run is a 'publisher', and requires a Platform API endpoint for connection, it will not work with any other type of API endpoint)
