First create an artful lxc container, it's old enough we can use it to quickly cross-build mono for the older glibc available on Evercades.

sudo lxc launch ubuntu:a/armhf armhf-artful
sudo lxc exec armhf-artful bash

Now let's fix artful's repo situation, this release is outside of the usual repositories due to being too old. We'll then install the packages.

sed -i 's$http://ports.ubuntu.com/ubuntu-ports$http://old-releases.ubuntu.com/ubuntu$' /etc/apt/sources.list

DOTNET Runtime for old GLIBC (ArmHF support included)!

Our problem here is that there are classes of devices that are stuck on very old glibc versions (e.g. 2.26) and armhf.

We're solving this by compiling the .NET 9 artifacts with an Ubuntu bionic (18.04) rootfs, this should be close enough to just work. At the time of writing this, we had only .NET 9 preview 4 with armhf support, so that's what we're using (tag: v9.0.0-preview.4.24266.19, you can change this if necessary).

    // The following nested structure does two things:
    // 1: Unwraps details about the function (e.g. argument type list,
    //    return type) with the template.
    // 2: Implements the dispatcher as needed (will extract from va_list and push)
    //    into the function call that is being wrapped, taking care to also return
    //    the value if applicable.
