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

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.

checking whether the /home/rroland/src/build-m2-cross/build-gcc/./gcc/xgcc -B/home/rroland/src/build-m2-cross/build-gcc/./gcc/ -B/home/rroland/opt-gcc-12/cross/aarch64-linux/bin/ -B/home/rr

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).
