Re: Bare metal Modula-2 on a Raspberry Pi-4 64 bit mode (Embedded aarch64)

[Robert Roland]

Okay, I retried this using a Debian Buster container with Docker, and success! It builds!

I'm guessing this is a difference between using GCC 8 and GCC 11 as the bootstrap compilers.

If anyone wants to do this like I did:

docker run -v /home/rroland/src:/root/src -v /home/rroland/opt-gcc-12:/root/opt-gcc-12 -it debian:buster

And you need a few additional apt packages:

apt install wget patch flex rsync libgmp3-dev python3-dev gawk bison

Other than adding the additional apt packages, I followed the rest of the instructions to the letter.

Thanks again, Gaius!

I get an error during the build, unfortunately. Same one I've gotten in the past when trying to create a cross-compiler that involves C++. I'm on openSUSE with GCC 11.2.1.

Hi,

I thought this might be of interest as a proof of concept to show gm2
can now be built as a cross compiler (either targeting GNU/Linux or
targeting bare metal).

and
