Hi, guys, I wanted to try it but I'm not able to compile anything and I don't understand the problem. Here is the log message from the arduino IDE on my linux mint VM. I had to install g++, and i'm using version 9.3.0. Am i missing something? Need other information? To me, it seems a memory problem, but i set the VM with 8Gb RAM, and still have 12Gb of free space on HDD.

Btw I love this project, what about LPT implementation? could transform an old PC into a freaking super IPC micro-controller lol

Thanks in advance

Hello!

I found this project from https://hackaday.com/2022/01/12/arduino-ide-creates-bootable-x86-floppy-disks/

Could you please add information about the license of this repository — is it allowed to copy, change and use the code in any purpose? It would be great to see any popular open source license.

I used the procedure here to update gcc from v9 to v11 with the option to select either using update-alternatives and also installed the gui galternatives to help configure and select the default compiler.

The demos build and run using Qemu in Linux Mint 20.3, I have not yet tried using a floppy on a real PC.

recipe.preproc.macros pattern is missing Error compiling for board Generic x86 computer.

Arduino would not recognize the new hardware folder until boards.txt was inside one of the subdirectories.

Building on windows 7, can test on a linux system later if necessary, I figure this was just a misplaced file.

I have a bootable flash drive upon which I store ISOs of various Linux distributions and other tools. For example, I can boot into an Ubuntu ISO like this:

menuentry "Ubuntu 20.04 [ejectable]" {
	set isofile="/images/ubuntu-20.04.2-amd64.iso"
	echo ">>> ISO file: ${isofile}"
	loopback loop $isofile
	linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile setkmap=uk eject noprompt splash toram iso-scan/filename=${isofile} --
	initrd (loop)/casper/initrd.lz
}

....or memtest86+ like so:

menuentry "Memtest 86+ 5.01" {
	linux16 /images/memtest86+.bin
}

(I have a full tutorial on it here: https://starbeamrainbowlabs.com/blog/article.php?article=posts/389-multiboot-2.html)

My question is this: Can I boot into boot2duino images using a similar approach from grub? If so, one could have many images on a single flash drive, and a nice menu to choose between them.
