Missing toolchain in BBxm Ubuntu 20.04 rootfs

I’ve installed the image from https: //rcn-ee.com/rootfs/eewiki/minfs/ubuntu-20.04-minimal-armhf-2020-05-10.tar.xz on my Begleboardxm but there is no toolchain.
Typing either gcc o g++ I get “command not found error”.
Where can I found the toolchain?

You’ll need to install it, these images are very small to start as a base for lots of users:

sudo apt update
sudo apt install build-essential
