I am trying to get Mono 2.10 working on a core-image-basic running on
qemux86 machine. I am using pokay-dylan-9.0.2 on a Debian 6.0.7 system for
the builds and been able to build and run images without issue. Yet, when
I went to add the meta-mono layer from, I started
running into problems.

Corlib not in sync with this runtime: expected corlib version 96, found
100. Loaded from: /usr/lib/mono/2.0/mscorlib.dll
Download a newer corlib or a newer runtime at
I dug into the mono build and figured out that I had a version mismatch
between 'mono' (builds the runtime for the target) and 'mono-native'
(builds a runtime for the build system and uses it to build the corlib).
The key was defining both of the following in local.conf, not just the
first line which is all I had originally.

PREFERRED_VERSION_mono-native = ""

Anyway, attached is a patch against meta-mono (from
git:// that makes these changes:
- Adds a comment to the README about the two configs above.
- Reconfigures mono to be built without X support, skip as desired.
- A few packaging tweaks, namely moving the bulky *.mdb (Mono debug
databases) to the -dbg package.
- Adjustment to QA packaging checks to resolve errors encountered.
- Moved the mono- folder in meta-mono/recipes/mono to
meta-mono/recipes/mono/files so the contents can be found.
- Quick fix to mono-xsp recipe to avoid parsing error, probably not the
fix to make if mono-xsp was going to be built (but I am not).

Hope that helps some one, it does myself as I can now run Mono apps in my
qemux86 target. Next challenge is to do the same with a qemuarm target
(actual hardware comes later :)!
Have you sent these fixes to the layer maintainer - Autif Khan
(autif.mlist@...) ? It would be good to get those integrated.
