Compiling on Mono?

Dobai-Pataky_BSSSSl · October 24, 2010, 10:52pm

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I know there is a special outdated branch provided by casualjim which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 nameTextContentProvider’ 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 nameTextContentProvider’ could not be found. Are you missing

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…

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

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?

Andrius_Bentkus · October 25, 2010, 5:22pm

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.

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.

Unless we target Mono… >.>

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 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.

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.

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.

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.

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.
