Raspberry Pi GPIO Benchmarks

Installation of libraries

WiringPi (strobe_wiringpy_gpio.sh):

git clone git://git.drogon.net/wiringPi
cd wiringPi
./build

Python RPi.GPIO (strobe.py):

sudo apt-get install python-rpi.gpio python3-rpi.gpio

Python wiringpi2 (strobe_wiring2.py):

sudo apt-get install python-dev python-setuptools
git clone https://github.com/Gadgetoid/WiringPi2-Python.git
sudo python setup.py install

Ruby (strobe_wiringpi2.rb)

sudo apt-get install ruby-dev
sudo gem install wiringpi2

C BCM2835 (strobe_bcm.c)

curl -O -J -L http://www.airspayce.com/mikem/bcm2835/bcm2835-1.42.tar.gz
tar xzf bcm2835-1.42.tar.gz
cd bcm2835-1.42
./configure
make
sudo make install
cd ..
gcc strobe_bcm.c -O3 -lbcm2835 -o strobe_bcm

C WiringPi (strobe_wiring*.c)

(install WiringPi as above)
gcc strobe_wiring.c -lwiringPi -o strobe_wiring
(similar commands for other 2 versions)

Perl BCM2835 (strobe.pl)

wget http://search.cpan.org/CPAN/authors/id/M/MI/MIKEM/Device-BCM2835-1.9.tar.gz
cd Device-BCM2835
perl Makefile.PL
make
sudo make install

Benchmarks themselves need to be run with sudo to access GPIO.
