A problem about example1a

[lzheng28]

I run the code of "Example 1a - Basic transmission and distribution powerflow" and find it doesn't work, and the outcome is

lei@lei-VirtualBox:~/Desktop/Example_1a$ helics run --path cosim_runner_1a.json
[INFO] Running federation Example-1a-T-D-Cosimulation-HELICSRunner with 2 federates.
[INFO] Running federate TransmissionFederate.
[INFO] Running federate GridLABDFederate.
[ERROR] Something went wrong with federate TransmissionFederate. Please check the log files.

And the log file of TransmissionFederate.log is

Traceback (most recent call last):
File "Transmission_simulator.py", line 77, in
fed = h.helicsCreateValueFederateFromConfig("Transmission_json.json")
File "/home/lei/anaconda3/lib/python3.6/site-packages/helics/helics.py", line 901, in helicsCreateValueFederateFromConfig
return _helics.helicsCreateValueFederateFromConfig(configFile)
_helics.HelicsException

The log file of GridLABDFederate.log is

ERROR [INIT] : gldcore/module.c(422): module 'connection' load failed - libfncs.so.1: cannot open shared object file: No such file or directory

Environment:
helics --version (0.4.2-HEAD-97b544e) (I install the helics-cli)
gridlabd --version (GridLAB-D 4.2.0-0 (McNary [:]) 64-bit LINUX RELEASE)
pypower version (5.1.5)

Could you please help me find what leads to this problem or help me solve this problem? Thank you so much.

I found that I didn't install GridLAB-D with HELICS correctly, if I install them correctly, I can run the example successfully.
