MonoGame "hello world" build failing (System.OverflowException: Value was either too large or too small for an Int64)

[endel]

Hi there,

I'm trying to compile a simple "hello world" without success.

I'm under OSX (10.11.4), using Xamarin Studio to compile. Am I missing something? Should it work on my environment?

Hello world source code

Stack trace + error message:

The stack trace isn't providing much information, but it looks like one of the assemblies you're translating contains a UInt64 enum with a very large enumerant, maybe? I haven't ever tested with monomac.

@endel, please try to change JSIL/TypeInformation.cs around line 698. Please replace:

                    if (field.HasConstant)
                        enumValue = Convert.ToInt64(field.Constant);

with

                    if (field.HasConstant) {
                        if (field.Constant is ulong) {
                            enumValue = (long) (ulong) field.Constant;
                        } else {
                            enumValue = Convert.ToInt64(field.Constant);
                        }
                    }

Could you report if it'll help?

Thanks for your quick reply @iskiselev and @kg.

@iskiselev it did compiled with this change! I just couldn't make it actually run in the browser. Maybe I'm missing something. I'll have a deep look during the weekend. Cheers!
