@Dimple. I just spent a bit of time investigating this and found out that it works fine under Mono (on Linux) and only fails under .NET on Windows. I’m thinking of a more radical fix in the trunk line (possibly by allowing a full class to be used including using statements).

Unfortunately, in 0.6.7 things are a little more difficult since I don’t really want to start putting in arbitrary hardcoded references. If you’re desparate, in Compiler.cs in the OpenSim.Region.ScriptEngine.Shared.CodeTools project, you could try adding an extra reference in the CompileFromDotNetText() method. That is, where you see

parameters.ReferencedAssemblies.Add(Path.Combine(rootPath,
“OpenSim.Region.ScriptEngine.Shared.dll”));
parameters.ReferencedAssemblies.Add(Path.Combine(rootPath,
“OpenSim.Region.ScriptEngine.Shared.Api.Runtime.dll”));

you could try adding something like

parameters.ReferencedAssemblies.Add(”System.Xml.dll”);

though I couldn’t guarantee this will work. If you try it, I’d be interested in the feedback.

Justin/Su,

I am getting same System.XML error (Error CS0234: The type or namespace name ‘Xml’ does not exist in the namespace ‘System’ (are you missing an assembly reference?)
, it recognizes System.IO, but cannot recognize System.XML.

I am working on 0.6.7 opensim. Any ideas? Please Help!!!

Regards,
Dimple

@su - Not to my knowledge. But I’d be happy to take a look at your code if you e-mail me your OpenSim.ini and the exact text of what you’re trying to run.

@justincc- yes i was using the full names. Sine my own code was not working, I just copy-pasted your example code. Is there anything else we have to add to your code?

@su - I just tried the script I have in the blogpost on the most uptodate OpenSim (97c18caa766e2dd72b152b78827ef554f2054f8c, 22nd Sept 2009) and it works fine (and this under XEngine). Are you using the full names of types (e.g. System.Xml.XmlTextReader rather than just XmlTextReader)? Unfortunately, C#’s normal using statements will not work with OpenSim’s C# ’scripts’.

@su - Hmm, thanks for the data, I’ll go back and give this a test when I can. It sounds a little strange to me.

i reported a bug to mantis (http://opensimulator.org/mantis/view.php?id=4137) and according to the response I got from Melanie, the allowed references are hardcoded into the compiler. But since it is working for you, does it mean that you can change the compiler settings to include the references needed?

I was able to resolve the second error. problem there was with the Script Engine. In my case, when the script engine was “XEngine”, it did not work. Then I changed it to “ScriptEngine.DotNetEngine” and now the compiler detects C#. but the error with the compiler not being able to detect System.Xml is still there

Hi justincc,
I installed Opensim in my machine in standalone mode and set
AllowedCompilers = lsl,cs

I am also getting the same error that Robert got: “Primitive: Error compiling script:
The compiler for language “cs” is not in list of allowed compilers. Script will not be executed!”

I am using OpenSimulator Server 0.6.6.
Were you being able to figure out the reason for this?

Rgds,
Su
