My motivation for using wiringPi is that I want to use it with Ruby. I had looked at a couple of alternative Ruby gems however 1 didn't work and the other depended upon wiringPi.
The download, installing, and running of wiringPi shouldn't take you 5 minutes if you have an LED and resistor already hooked up to the Raspberry Pi.
sudo apt-get install git-core
If you get any errors here, make sure your Pi is up to date with the latest versions of Raspbian:
sudo apt-get update sudo apt-get upgrade
To obtain WiringPi using GIT:
git clone git://git.drogon.net/wiringPi
If you have already used the clone operation for the first time, then
cd wiringPi git pull origin
Wil l fetch an updated version then you can re-run the build script below.
cd wiringPi ./build
Type the commands:
gpio mode 0 out gpio write 0 1 gpio write 0 0
Alth ough I prefer to use the actual GPIO pins numbers
gpio -g mode 4 out gpio -g write 4 1 gpio -g write 4 0
