Hi all,

This is an update for the first week of the first milestone for 
SAOC 2020.

My idea for the first two weeks (the original outline is at [1]) 
was to:
- try to build the druntime for an embedded architecture (the 
microcontroller I’m working with has an ARM Cortex-M4 CPU).

Before the start of the SAoC 2020 I tried to build it using the 
‘lcd-build-runtime’ tool, but an cmake error [2] that I have not 
been able to resolve yet has stopped me.

This week:
- I followed Denis’ advice [3] and tried to build the runtime 
using the Meson build system.
- I have not succeeded yet and somehow there are still errors to 
resolve, but I have a feeling I am close.

In the following week:
- I hope I’ll manage to build the runtime so that I’ll have a 
working environment to help me in the next months of SAoC 2020.

So it looks like you haven't even tried what I wrote in

I tried this, but at that moment I couldn't make it work. I will 
try it again these days and will come with an update. Thanks for 
the advice :D

 [1]) was to:

It is important to remember that it is impossible to build 
default druntime just for some (hardware) architecture.

druntime needs architecture + "OS", because it is need to call 
something for memory allocations (malloc) and for other stuff 
like this. This "OS" can be reduced to few your own functions or 
maybe to TockOS calls or to baremetal libc implementation.

(Current druntime slightly uses libc calls. This is not as bad as 
it might seem, this is not touches "purity" of the language. In 
fact, libc isn't only C library, but de-facto standard for access 
to OSes functions.)
