Grin-miner build error

Tech Support
1

Just wondering if anyone is still familiar with it:

I am building in multipass (VM) like this:

multipass launch --name grin-miner --mem 2G --disk 10G --cpus 2 bionic
curl https://sh.rustup.rs -sSf | sh; source $HOME/.cargo/env
sudo apt-get update
sudo apt install cmake libncurses5-dev libncursesw5-dev zlib1g-dev libssl-dev pkg-config
sudo reboot
git clone https://github.com/mimblewimble/grin-miner.git
cd grin-miner
git submodule update --init
cargo build

I am commenting line 40 and uncommenting 38 in Cargo.toml to disable building CUDA plugins:
https://github.com/mimblewimble/grin-miner/blob/master/Cargo.toml

I get this error:

error: failed to run custom build command for cuckoo_miner v4.0.0 (/home/ubuntu/grin-miner/cuckoo-miner)

Oh right, grin-miner has precompiled releases too.

-bash: /usr/local/bin/grin-miner: cannot execute binary file: Exec format error

I think this is the answer I was looking for, that of course you can’t just run this on M1/ARM as is.
