/**

\file mainClient.cpp
|
|
|
|
This file is an example of how to implement the slsDetectorUsers class
|
|
You can compile it linking it to the slsDetector library
|
|
|
|
g++ mainClient.cpp -L lib -lSlsDetector -L/usr/lib64/ -L lib2 -lzmq -pthread -lrt -lm -lstdc++
|
|
|
|
where,
|
|
|
|
lib is the location of libSlsDetector.so
|
|
|
|
lib2 is the location of the libzmq.a.
|
|
[ libzmq.a is required only when using data call backs and enabling data streaming from receiver to client.
|
|
It is linked in manual/manual-api from slsReceiverSoftware/include ]
