Unable to find the file 'OxyPlot.dll' on OS X

[jmchapman]

I have mono 3.8, I am running F# interactive from within emacs on OS X mavericks.

I downloaded FSharp.Charting.Gtk.0.90.7 from nuget. I put it in ~/Desktop/packages/. I have a script containing the following at ~/Desktop/test.fsx:

load "packages/FSharp.Charting.Gtk.0.90.7/FSharp.Charting.Gtk.fsx"

open FSharp.Charting Chart.Line [ for x in 0 .. 10 -> x, x*x ]

Trying to run the three lines above gives the following error:

"> [Loading /Users/james/Desktop/packages/FSharp.Charting.Gtk.0.90.7/FSharp.Charting.Gtk.fsx]

I created symbolic links to OxyPlot.dll and OxyPlot.GtkSharp.dll in /Users/james/Desktop/packages/FSharp.Charting.Gtk.0.90.7/. I then get the following error and and a something called mono-sgen appeared in my dock:

There is some inconsistency between script resolution rules on Mono and .NET. Could you try opening FSharp.Charting.Gtk.0.90.7/FSharp.Charting.Gtk.fsx, sending the whole lot to FSI and then going back to your chart file and sending that without the initial #load?

This is not a good workaround, but I want to check that it works ok in that case.

Doing that gives you:

> Chart.Line [ for x in 0 .. 10 -> x, x*x ];;
val it : ChartTypes.GenericChart =
  Error: An exception was thrown by the type initializer for Gtk.Widget

Problem still persists - been trying everything, can't get it to run, hanging on mono-sgen

The Gtk.Widget issue looks like a duplicate of issue #29
