Mono on Raspberry Pi

I've seen a lot of talk about running Mono/.NET code on the Raspberry Pi. Has there been any success in actually running any Mono code on a Raspberry Pi?

On their site, they list several Linux distributions that work on the device and some of these distributions include Mono. However, none detail whether Mono works on it.

Is there a working implementation?

I have managed to run my Delta Forth .NET compiler on Debian 6.0 (Squeeze) and Mono. It worked flawlessly with full binary compatibility, the only thing I had to do was to recompile the code to target .NET 3.5 (instead of 4.0) since Mono on Debian lags a bit regarding .NET versions.

The compiler is not a trivial .NET application so I was happy to actually see the compiler in action on my tiny Raspberry Pi.

The actual steps I took to make the magic happen were (I recall from memory):

• Install the Mono runtime using: sudo apt-get install mono
• Invoke the compiler itself using: mono DeltaForth.exe file_to_compile.4th

That is all. The most challenging part of this endeavor was to transfer the files from my Windows machine to Raspberry Pi using a flash drive :-)

The folks on the Raspberri Pi board are reporting that Mono does indeed work, at least for simple applications.

Mono on the Raspberry Pi is possible and reasonably easy to set up. The following assumes you're on Debian. This is taken from my blog that offers a number of Raspberry Pi tutorials

A note: the standard Mono runtime currently available only supports up to .NET 3.5 unless you compile from source yourself.

>So you want to start developing some applications for your Raspberry Pi but your knowledge of programming is limited to the modern .NET languages such as VB.NET and C#. Not a problem!! Welcome to the world of Mono, an open source cross-platform and compatible version of the .NET framework. By using a development IDE such as Visual studio, or even better MonoDevelop you can produce EXE files that will run on your Raspberry Pi. All you need to do is to install the Mono run times on the Raspberry Pi. To do that we enter the following lines.

sudo apt-get update

sudo apt-get install mono-runtime

>As mentioned in other tutorials the first line is used to update the APT-GET package manager to ensure it is using the latest sources for downloading your packages. The second line installs and prepares the runtimes for use. That's it, now to run a Mono developed EXE file. Just simply prefix the command with the word mono as shown below.

mono myprogram.exe 

Yes. I've successfully run Mono based Winforms and Webforms apps (XSP). Detailed How to is available in my blog

Hard float support is now in mono 3.2.7:

The latest source can be installed from git. It should be something like this:
(remove previous mono installations first)

sudo apt-get update
sudo apt-get install git build-essential automake autoconf libtool gettext
git clone git://github.com/mono/mono.git
cd mono
./autogen.sh --prefix=/usr/local
make get-monolite-latest
make EXTERNAL_MCS="${PWD}/mcs/class/lib/monolite/gmcs.exe"
sudo make install

This is how "mono -V" looks like on my raspberry:

A quick test seems to work fine:

csharp> Math.Pow(2,4);
16

On my Raspberry Pi running the Fedora 18 remix, all I needed was:

    # yum -y install mono-devel

To Check:

    # csharp
    Mono C# Shell, type "help;" for help
    Enter statements below.
    csharp> Console.WriteLine("Hello, I am PI");
    Hello, I am PI
    csharp>  

I was able to run my .NET exe on raspberry pi (debian).

Install mono - http://logicalgenetics.com/raspberry-pi-and-mono-hello-world/

then run your exe as mono something.exe

You can run x86 version of Mono on Raspberry Pi using ExaGear Desktop software.

It allow to run almost all x86 apps and even install Wine to run Windows apps.

They say that Firefox works faster than even native ...
