Forum: IronRuby Compiling on Mono?

Hello,
I know there is a special outdated branch provided by casualjim which 
lets
you compile ironruby on mono/linux, but what about the current version? 
Can
I compile it with mono? I tried using the 2.8 release of mono to compile
ironruby 1.1.1, but it would result in an error:

        Runtime/SavableScriptCode.cs(40,47): error CS0246: The type or
namespace name `ScriptCode' could not be found. Are you missing a using
directive or an assembly reference?
        Runtime/LanguageBoundTextContentProvider.cs(26,62): error 
CS0246:
The type or namespace name `TextContentProvider' could not be found. Are 
you
missing a using directive or an assembly reference?
        Runtime/SourceStringContentProvider.cs(25,57): error CS0246: The
type or namespace name `TextContentProvider' could not be found. Are you
missing a using directive or an assembly reference?
        Runtime/NullTextContentProvider.cs(24,51): error CS0246: The 
type or
namespace name `TextContentProvider' could not be found. Are you missing 
a
using directive or an assembly reference?
        SourceFileContentProvider.cs(27,55): error CS0246: The type or
namespace name `StreamContentProvider' could not be found. Are you 
missing a
using directive or an assembly reference?

I have this branch successfully compiling on Mono:
http://github.com/mletterle/ironruby/tree/linux

compile with xbuild /property:TreatWarningsAsErrors=false
/property:DefineConstants="DEBUG MONO" Ruby.csproj

The interesting part is how did you get the other projects that 
Ruby,csproj
depends on to build.....

Looking at the Microsoft.Scripting.* projects so no reference to Mono

You may have to compile some of the dependency libraries WITHOUT the
MONO constant...

I got it compiling, there is a missing reference for Mono.Posix, one bad
cast and you need to use CCI in the constants. Does someone know what 
CCI
should be?

I can't patch the csproj with the missing reference because it would 
break
building on windows. Creating another set of csproj for the a mono build
would be madness. Do csproj'ects support something like ifdef or is it
possible to include a reference only when mono is used?

And the other change I made was a one liner, I don't think that 
attaching an
entire patch is is really necessary for it. Just run xbuild with CCI: 
xbuild
/property:TreatWarningsAsErrors=false /property:DefineConstants="DEBUG 
MONO"
Ruby.csproj
and look at the warning outputs... O for god sake, I'll just attach it.
I used this branch: http://github.com/mletterle/ironruby/tree/linux as 
the
base.

Doing a google search I found this.I have not had a chance to try it out 
maybe this would 
work.http://groups.google.com/group/DotNetDevelopment/m...

References in project files can be conditional. I don't have an example 
handy, but unless things have changed in the last year :), the project 
files should already have a conditional dependency on the Silverlight 
assemblies.

It is really possible, I guess I was too lazy to do the search myself,
thanks for googling :)

There is just another question, maybe one of the former developers will
know, why are there 2 build systems now? Why is there a *.build.csproj 
for
every *.csproj? Isn't that redudant like the suggested rakefiles?

I think we should not have any #if MONO conditionals. That would mean 
we'd need a different set of binaries for Mono, Moonlight, etc. almost 
doubling the number of flavors we have today (desktop CLR, Silverlight 
4, Silverlight 3).
Now that Mono 2.8 is released we can use memory mapped files (it wasn't 
available when I wrote this code). We don't need to use P/Invokes 
anymore.  I have the V4 implementation somewhere almost working so I 
might be able to check it in soon.

How do we want to handle things that CAN be worked around in Mono
before they're patched then?

I agree that the same binaries should run in either location, but Mono
necessarily is always playing catchup.

Once we'll have CI server test against Mono we'll discover the problem 
right away and don't check in anything that would be broken on Mono.
I suggest we implement the workaround, file bugs into Mono and IronRuby 
bug trackers, and add a comment to the code with explanation and a link 
to the filed IronRuby bug. When the bug is fixed in Mono we go and 
remove the workaround to keep the code base clean.

Then it some cases, I think it might make sense to avoid using a
feature in IR which is not yet available in the current stable release
of Mono.

I completely agree.

Everytime I worked on making IronRuby working on Mono (IronRuby is
constantly kicking Mono's tires, which is very good), I used the
following workflow:

* Avoid any specific Mono branch.
* Fix any path/casing issue directly in the build files (csproj, ...)
* If the code compiles with .net's csc, and doesn't with Mono, file a
bug in Mono, and use a code form that works for both, if possible.
* If the code doesn't compile because of a Mono feature (better unused
local variable/field detection), fix directly in the source.

It also may happen that IronRuby triggers a bug in Mono, and thus,
requires Mono from master to compile/work.

Tracking and removing again would be overhead but I guess there is no 
other
way to do it.

Well, some of us don't need the CI server as we're programming against
mono already ;)

FWIW, I'm looking into getting the linux CI server back up and running
with CJ's help.

But agreed. I can back out the ifdef I made and just use the work 
around.

Also, should we be targeting a specific version of mono, or just
trunk?  Something else to think about.... historically I always used
trunk to allow mono to "catch up" as far as possible since the
majority of work was done against .NET... it seems this might be a
good chance to change that disconnect.

We have actually always targeted Mono and IronRuby mostly works on it. 
Of course we found a bunch of Mono bugs for which we either implemented 
a workaround or filed a bug if the workaround would be too convoluted.

By "target" I meant "do primary development against" ^_^

BTW my branch is updated, I reset to the current master/HEAD so it
should be a lot cleaner, also undid the mono ifdef, commented out the
original calls explaining that Mono doesn't support it yet.  Need to
work on some repos/patches/bug filing for mono now.

The following two bugs have been filed against mono, there are current
work arounds  implemented on my linux branch to account for them:

https://bugzilla.novell.com/show_bug.cgi?id=649159
System.Threading.Monitor does not contain TryEnter(*, ref bool) methods

https://bugzilla.novell.com/show_bug.cgi?id=649448
REGRESSION: labels inside of delegates defined as a method argument
