Hi Sony.
... too many fuzzy questions at a time ! ...
It's hard to help you, although I would be happy to do so.
I saw you tried to use Proview for a few days only.
At the beginning, I spent some weeks before success.
If I can give you some kind of advice, you better start to follow all steps in the "getting started guide"

I sometimes got the message
"GLib-CRITICAL **: Source ID "xxxxx" was not found when attempting to remove it".
and it was not "critical"
If you can't build, there is a mistake in your plc program or anywhere else. Try to make one change at a time to find the issue
pwr55 is built for Ubuntu 16.04 (i.e. Mint18)
