Help running the consumer example
So I’ve completed these steps successfully:
- I have built the electron libraries
- I have built the consumer example program
Locate reference : ./Elektron-SDK-1.4.0.L1.linux/setup/Elektron-SDK-1.4.0.L1.linux.rrg/Cpp-C/Ema/Examples/Training/Consumer/100_Series/100__MarketPrice__Streaming/Consumer.h
- I have created a password for our machine id in our UAT environment
- I run the executable from the directory where the EmaConfig.xml from the example code is located
Upon running the code, which subscribes to IBM.N on serviceName ELEKTRON_DD with consumerName Consumer_3
I get the following error:

I can supply the source code, but it’s the same as the example. Is it possible to get some help in figuring out what this error message means? Could it be that i'm not providing proxy information?
Also my version of curl is
Also as it seems there’s a curl issue: this I my version

Hello all,
The investigation was consequently taken offline.
After both OpenSSL and curl libraries were found at runtime,
the encrypted channel consumer example runs properly.
Not sure that what version of Linux you currently use?
Can you copy libcurl.so from "[ESDK Install Path]/installdb/RHEL6_64_GCC444/Optimized /lib64/" to running directory? and then test the issue again.
Also please make sure that you already set LD_LIBRARY_PATH to the folder which contains libcurl.so
It looks like the example build with optimized lib so you have to export the PATH to Optimized folder as mentioned in this tutorial
export LD_LIBRARY_PATH=<ESDK root>/installdb/RHEL6_64_GCC444/Optimized/lib64
That helped, libcurl seems to be working...
Now i get this error, i and using the machine id as the username, the password i set on the web
as the password. what should the client id be?

Hello @epfeuffer,
You should only need to pass into example 113
-username ( machineid, should look like "GE..." )
-password (the very long password you setup yourself)
no additional client id is required.
Please read more details in EMA Quick Start - Connecting to Elektron Real Time in Cloud
Because it appears something is invalid about the reds you are passing, please verify if what you are passing is username and password is as expected?
(There is an email-based username and the corresponding short password, these are not the right parameters to pass into example)
i've taken the client id out and get this
