Building MonoDevelop for the PINE64

4 Dec 2017 Update
These instructions will not work with the latest versions of Mono and MonoDevelop from github. I tried compiling from scratch on a new image, and they will work with the following versions listed below. You can checkout the specific tags immediately after cloning the corresponding repositories before you start building.
Mono 4.8.1.0 – git checkout tags/mono-4.8.1.0
MonoDevelop 6.1.0.5441 – git checkout tags/monodevelop-6.1.0.5441

My PINE64 is here and the first thing I decided to do was build MonoDevelop which I’ll use to manage C# projects, since most of the code I’ll be writing for my autonomous project will be in C#. I’m using the longsleep Ubuntu Xenial image as a base, so these instructions assume that this is what you have installed. You can adapt as required based on your distro.

Of course, the easiest way to get MonoDevelop installed is by using the package manager. The version is also fairly recent (4.2.1.102), so you can choose skip the rest of this post if you prefer. Simply run the apt-get install command and all required dependencies will also be automatically installed.

Most of the steps will be similar to the MonoDevelop for Raspberry Pi build post, but we’ll be skipping fsharp altogether. I cloned the fsharp repository but the make process failed due to the following error:

F# is only required for the fsharpbindings extension and I don’t plan on using that. There appears to be an fsharp package which you can install using apt, but this will also install the mono 4.2.1 dependencies. If you’re fine with using an older version of mono and would still like to build MonoDevelop, then you can also skip the steps up till Build MonoDevelop.

So let’s get started!

Install all prerequisites
Git is required to clone the source repositories for Mono, MonoDevelop and dependencies. The other packages are required for building MonoDevelop dependencies from source.

 

Pre-build: NuGet certificates
The MonoDevelop build process makes use of NuGet at certain points. You will need to import certificates into your certificate store using the following commands.

 

Build Mono
This step is fairly straightforward. Clone the mono source repository and run the build process.

This build will take a while. If you wish to run the mono and mcs test suites, you can do a make check before make install.
 

Build MonoDevelop dependencies
MonoDevelop requires gtk-sharp and gnome-sharp to be installed on the system. To build gtk-sharp.

gnome-sharp follows a similar process.

Some reference PCL Assemblies are required for the build to complete. You will need to build a deb package and install following the instructions below.

Remove mono-xbuild from the list of dependencies in the control file, save and close. Then proceed with the following commands.

 

Build MonoDevelop
First, we clone the monodevelop repository and initialise the submodules using git.

Next, we remove references to fsharp. The assumed working directory for these steps is the top-level monodevelop source directory.

Remove the external/fsharpbinding/MonoDevelop.FSharpBinding/FSharpBinding.addin.xml \ line, save the file and close.

Comment out or remove the following lines in the file and save your changes. To comment out the lines, simply prefix each line with the # character.

Then we can go on to build the IDE.

You can run mono main/.nuget/NuGet.exe update -self if you get the following error after running make.

Once the build is successfully completed, you can run the application using monodevelop. If you have X11 forwarding enabled for your SSH session, you should see the MonoDevelop IDE on your screen after a couple of seconds.
