Define minimal set of requirements (?)

[wilhelmagren]

I realized I can't build the Go code because the Arrow module requires at least Go v1.15, and on my Raspberry Pi 4 I only have v1.14.4 atm. I will try and upgrade this, but it made me think about defining a clear minimal version for all requirements.

First could be the obvious:

• Go version >= 1.15

if the wanted Arrow module is to be v9.0.0...

Also, I remember that Cargo does not build the Rust code if the rust compiler is not the latest update, IF we want the latest Arrow crate version. But we are using an older Crate version, so no problem atm.

For anyone interested in installing the right Golang version, and setting environment variables for Raspberry Pi 4 architecture (almost correct):

wget https://go.dev/dl/go1.19.1.linux-armv6l.tar.gz
sudo tar -C /usr/local -zxf go1.19.1.linux-armv6l.tar.gz
rm go1.19.1.linux-armv6l.tar.gz

export GOOS=linux
export GOARCH=arm
export GOARM=7

As you probably can see we are downloading armv6l Golang version, but Raspberry Pi 4 has architecture armv7l GNU/Linux, this works but is not optimal I guess.
