Experiments with Go and SDL2

christophe@pallier.org

This is just a few proof of concept demos of programming psychological experiments using Go.

Prerequisites

github.com/veandco/go-sdl2 will be downloaded during the first compilation.

The library SDL2 must be installed.

• Under Linux Debian-like:

  sudo apt install libsdl2-*

• Under MacOS:

    brew install sdl2{,_image,_mixer,_ttf,_gfx} pkg-config
  

Compilation

Each subfolder is independent.

For example, to compile the streaming code:

cd streaming
go build streaming.go
    ./streaming

Note: Installation of Go a Raspberry Pi

Following the instuctions at https://www.e-tinkers.com/2019/06/better-way-to-install-golang-go-on-raspberry-pi/, save the following script in ~/bin/go_installer.sh

export GOLANG="$(curl -s https://go.dev/dl/ | awk -F[\>\<] '/linux-armv6l/ && !/beta/ {print $5;exit}')"
wget https://golang.org/dl/$GOLANG
sudo tar -C /usr/local -xzf $GOLANG
rm $GOLANG
unset GOLANG

and run it:

 chmod +x ~/bin/go_installer.sh
 ~/bin/go_installer.sh
