IronRuby + Mono + WinForms issue

Andrew_SSTownley · November 26, 2009, 12:12pm

I sent this to Thibaut, but I probably should’ve sent it to the whole
list since it probably isn’t directly related to his work (sorry
Thibaut!).

Thanks to Ivan’s pointer to mono builds, I was able to get IronRuby to
work as I would’ve expected. However, it doesn’t seem able to find the
WinForms stuff that I clearly have on my machine:

$ locate System.Windows.Forms
/usr/lib/mono/1.0/System.Windows.Forms.dll
/usr/lib/mono/gac/System.Windows.Forms
/usr/lib/mono/gac/System.Windows.Forms/1.0.5000.0__b77a5c561934e089

/usr/local/ironruby/lib/ironruby/System.Windows.Forms.rb
/usr/local/mono-2.4/lib/mono/1.0/System.Windows.Forms.dll

/usr/local/mono-2.4/lib/mono/gac/System.Windows.Forms/2.0.0.0__b77a5c561934e089/System.Windows.Forms.dll.mdb

$ which mono
/usr/local/mono-2.4/bin/mono

$ ir -v
IronRuby 0.9.3.0 on .NET 2.0.0.0

$ cat /tmp/test.rb
require ‘System.Windows.Forms’

$ ir /tmp/test.rb
:0:in `require’: no such file to load – System.Windows.Forms
(LoadError)
from /tmp/test.rb:1

I’ve even tried explicitly including the .NET 2.0 libraries as part of
the LD_LIBRARY_PATH, but that didn’t work:

$ echo $LD_LIBRARY_PATH
/usr/local/mono-2.4/lib:/usr/local/mono-2.4/lib/mono/2.0

Obviously, there’s still a piece of the puzzle that I’m missing. Any
ideas?

Thanks in advance,

ast

what’s the output of your pkgconfig path?

ivan@debian-stage:~
Â» pkg-config --variable=libdir mono
/usr/local/mono/lib/pkgconfig/…/…/lib

ivan@debian-stage:~
Â» echo $PKG_CONFIG_PATH
/usr/local/mono/lib/pkgconfig

I added these lines to my .bashrc file

export PKG_CONFIG_PATH=/usr/local/mono/lib/pkgconfig:$PKG_CONFIG_PATH
export PATH=“~/bin:/usr/local/mono/bin:$PATH”

Yeah, I have a specific mono-2.4 environment script that I source based
on notes from here:
http://www.centriment.com/2009/04/01/building-mono-24-from-source-on-ubuntu-810/

#!/bin/bash
MONO_PREFIX=/usr/local/mono-2.4

Yes.

}

public HelloWorld ()

}
}

k

I used to set those env. variables but the only one you really need is
the
PKG_CONFIG_PATH one if that is the only mono version on your system and
it’s
installed in a non standard location (outside /usr or /usr/local)

On ubuntu there is a package on launchpad called monoxide which has the
2.4.2.3 release as a .deb package… might be easier to get going.
https://launchpad.net/~directhex/+archive/monoxide

Here’s the script I use to build mono from trunk on both ubuntu and
debian.

ivan@debian-stage:~/src/mono
Â» cat ./update_mono
#!/usr/bin/env bash
#svn co svn://
anonsvn.mono-project.com/source/trunk/{cecil,debugger,gtk-sharp,libgdiplus,mcs,mod_mono,mono,mono-addins,mono-basic,mono-tools,monodevelop,moon,olive,rocks,winforms,winforms-tools,xbuild,xsp,gnome-sharp,gnome-desktop-sharp,gluezilla,monodevelop-visualizers,monocov}

svn up
{cecil,debugger,gtk-sharp,libgdiplus,mcs,mod_mono,mono,mono-addins,mono-basic,mono-tools,monodevelop,moon,olive,rocks,winforms,winforms-tools,xbuild,xsp,gnome-sharp,gnome-desktop-sharp,gluezilla,monodevelop-visualizers,monocov}

cd mono
make distclean
./autogen.sh --prefix=/usr/local/mono --with-moonlight=yes
–with-libgdiplus=sibling --with-profile4=yes
make
sudo make install
cd …

#… build script for the extra libs like gtk-sharp, gnome-sharp etc.
all
the way to monodevelop

As an interesting side-note (and maybe a crucial point), I remembered I
had a sample I used the last time I looked at IronRuby back in April.
This one actually runs fine with no errors.

Do you really have to specify the whole assembly information with each
require?

$ cat formtest.rb
require ‘mscorlib’
require ‘System.Windows.Forms, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089’
require ‘System.Drawing, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a’

Application = System::Windows::Forms::Application
Form = System::Windows::Forms::Form
MessageBox = System::Windows::Forms::MessageBox
Button = System::Windows::Forms::Button
Point = System::Drawing::Point

class MyForm < Form

def initialize
self.text = “My .NET Form from Ruby”

@button = Button.new
@button.location = Point.new 150, 150
@button.text = "Click Me!"

my_click_handler = Proc.new {|sender, e| MessageBox.show 'Hello from

Ruby!'}
@button.click(&my_click_handler)

self.controls.add @button

end
end

my_form = MyForm.new
Application.run my_form

I’m a bit confused at this stage…

and as to why you’re seeing that there is because

require ‘System.Windows.Forms, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089’

is the only line of content in the file

lib/ironruby/System.Windows.Forms.rb

because paths are case sensitive it was looking in lib/IronRuby for the
file
System.Windows.Forms.rb but couldn’t find it and told you about it.
The ir.exe.config file holds the initial search paths for IronRuby.

I came across this issue when I tried to use gems it took a while before
I
got to 1 + 1 = 2

Wow. Yeah, I can see why that too awhile!

Thanks for the explanation. I understand the issue here, and I see the
difference between the two versions.

Thanks also for the build script. That will help a lot going forward.
I’m just about to set up (build) Mono 2.4 on another Ubuntu 8.04
machine, so that looks the business! Is the whole script available
somewhere? I know I could probably just finish it myself fairly
quickly, but if you’ve already got one that works, that’d be very
cool.

I don’t really use any other of the default Ubuntu mono apps, but I
didn’t want to deal with dependency-hell with apt to try and remove only
what I didn’t actually need. I figured it’d just be safer to build from
source, use the source script to toggle the environment and leave well
enough alone. I do the same thing to cycle between several versions of
the JDK when I’m doing that sort of thing too, so it isn’t a new trick.

What I ought to do is summarize all of this nicely into a blog post, but
I’ve issues with my blog at the moment. At least I have the emails, and
I’ll likely be going through this again after a while to set up another
machine. By then, I should have my blog sorted!

Thanks so much for all your help!

Only on debian apparently and only with version 0.9.3, because it works
on
my mac.

When I try it with 0.9.0 - 0.9.2 it works :S

Casing has changed for the lib/ironruby folder apparently it’s now
lib/IronRuby in the config file. That is fixed already in git on my
branch
but not in the build yet.

To fix it go into /bin/ir.exe.config

and change <set option=‘LibraryPaths’ language=‘Ruby’
value=‘…/lib/IronRuby
into <set option=‘LibraryPaths’ language=‘Ruby’ value=’…/lib/ironruby

or

go into /bin/ir

and add the following 2 lines under the shebang line
export MONO_IOMAP=all
export MONO_MANAGED_WATCHER=1

and everything should work as expected.

The second option discards drive letters (windows), \ path separator
and
casing by adding MONO_IOMAP and enables the FileSystemWatcher.

You don’t need to require mscorlib anymore it’s implied.

require ‘System.Windows.Forms’
require ‘System.Drawing’

add form code here

Sorry for the bumpy ride getting started.
