So I decided to debug this out a bit for myself. Before I go too far, here
is how my require headers are setup:
require 'System.Xml.Linq, Version=188.8.131.52, Culture=neutral,
require 'System.Data.DataSetExtensions, Version=184.108.40.206, Culture=neutral,
require 'System.Data, Version=220.127.116.11, Culture=neutral,
require 'System.Xml, Version=18.104.22.168, Culture=neutral,
require 'System.Drawing, Version=22.214.171.124, Culture=neutral,
require 'System.Windows.Forms, Version=126.96.36.199, Culture=neutral,
Inside of my IronRuby specs, there is a call that, in ruby looks like this:
rargs = ['-o', 'C:\Users\pinvoke']
args = System::Array[System::String].new(rargs)
p = Rspec::Project::Runner::ProgramArguments.Parse(args)
The call to assign the results of Parse to P always fails unless I
a) Do what Ivan suggested and copy to the bin folder
b.) Modify ir.exe.config to include the path to the actual .dll
I was reading the source code this evening and noticed that during the
RubyContext buildup it only includes the following paths to resolve
I assumed this is was why if I dump my .dll into any of those paths it
Then when I looked at the loaded files, everything looked like it loaded
: "System.Xml.Linq, Version=188.8.131.52, Culture=neutral,
: "System.Data.DataSetExtensions, Version=184.108.40.206, Culture=neutral,
: "System.Data, Version=220.127.116.11, Culture=neutral,
: "System.Xml, Version=18.104.22.168, Culture=neutral,
: "System.Drawing, Version=22.214.171.124, Culture=neutral,
: "System.Windows.Forms, Version=126.96.36.199, Culture=neutral,
Here is where it gets fun!
The problem appears to be in the way IronRuby is resolving assembly
references from other already loaded assemblies. That is, if I make the
above spec calls (rargs /args/ p) the application blows up w/o the CmdParser
assembly in the path. The thing is that all the .Parse(args) method call is
doing is a wrapper to call into another assembly... the one that blows up as
not being found.
So, I decided to see what happened if I call the methods from the CmdParser
assembly directly and... everything works fine. Regardless of which path
the file is in :)
If I wasn't so tired I would try and trace back how the resolve was working
and why it wasn't checking the loaded files... however I am exhausted and
it's way past my bed time.
If this helps, here is the Fusion Log that got dumped:
