I was happy to see that multitasking is supported in Ada on the raspberry pi. This means that Ada Web Server should run just fine, so I hunted up the commands to get it installed. It's generally much easier to install the packages from the linux distro repository, and that's what I did using the commands below:
Starting with a fresh copy of raspbian, I installed the gnat Ada compiler and aws with the following commands:
sudo apt-get install gnat
sudo apt-get install libaws-bin libaws2.10.2-dev
I'm an emacs fan, so I also installed my favorite editor:
sudo apt-get install emacs
A quick hello world web server was written and everything seems to work!
