Raspberry Pi config: Metadata file `System.dll' could not be found

[dsjstc]

I’ve done a linux install of RapidScada 5.0.4 on a Raspberry Pi 3, and copied the appropriate files from my (working) Windows machine. I’ve triple checked the install steps, but I still have the following error in my ScadaServer/Log:

2017-01-26 11:46:15 <osmc><root><ERR> Error compiling the source code of the formulas: 
Line 0, column 0: error CS0006: Metadata file System.dll' could not be found

I don’t see a System.dll anywhere in the windows install, and I don’t see a reference to it in any of the XML files. Could this be related to the fact that I have a trial ChartPro plugin?

Hi,
The issue is not connected with Chart Pro plugin.
System.dll is a part of .NET Framework. I think something wrong in Mono .NET Framework. Could you check the installed version of Mono by executing the command below?

mono --version

What localization do you use? I recommend to set English localization. There were issues depend on this.

Localization is default. I’ve got mono 3.10, the latest available on Debian Jessie. Looking through the forum it looks like you tested on 3.28 — Are you on Raspbian? Or did you use an external repository?

$ mono --version

Are you on Raspbian?

Yes.

You can try to install latest Mono manually as written here http://www.mono-project.com/docs/getting-started/install/linux/
I did it on Ubuntu just for testing.
