Cross build git for linux/amd64 on MacOS M1, using podman

build.sh

# install podman
arch -arm64 brew install podman

# init podman
podman machine init
podman machine start

# build
podman build --platform linux/amd64 -t git-static-builder -f Dockerfile-build-git-static .

# verify
podman run --platform linux/amd64 -d --name git-runner git-static-builder /usr/local/git-bin/bin/git --version
podman run --platform linux/amd64 -d --name git-runner git-static-builder /usr/local/git-bin/bin/git clone https://github.com/xhd2015/xgo
 
# copy
podman cp git-runner:/usr/local/git-bin.tar.gz ./git-linux-amd64.tar.gz

# remove runner
podman rm -f git-runner

# check file (40M+)
file ./git-linux-amd64.tar.gz

# untar on target machine
tar -xzf git-linux-amd64.tar.gz -C /usr/local

There is another way to install newest git without building it:

# on newer ubuntu
apt-get download git
mv *.deb git-v2.43.0-linux-amd64.deb

# on another OS
dpkg -i git-v2.43.0-linux-amd64.deb
apt update
apt install -f # apply fix
