WiringPiのインストールをやってみた

WiringPiのdebファイルなんかは存在しないようなので，オリジナルサイトの手順道理にやってみた．

環境の確認

以前に，環境の最新版への更新をやっていたので，不要なはずだけど，とりあえず，手順どおりにやってみる．

gitのインストール

root@pi:/sys/class/gpio# apt-get install git-core
Reading package lists... Done
Building dependency tree      
Reading state information... Done
git-core is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
root@pi:/sys/class/gpio#

やはり，入ってた．

次に，環境の更新

root@pi:/sys/class/gpio# apt-get update;apt-get upgrade
Hit http://raspberrypi.collabora.com wheezy Release.gpg
Hit http://archive.raspberrypi.org wheezy Release.gpg
Hit http://mirrordirector.raspbian.org wheezy Release.gpg

いろいろ中抜き

Reading package lists... Done
Building dependency tree
Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
root@pi:/sys/class/gpio#

というわけで，特に，更新なし．

ソースの入手

pi@pi /srv/src $ git clone git://git.drogon.net/wiringPi

pi@pi /srv/src $  cd wiringPi/
pi@pi /srv/src/wiringPi $ git pull origin
Already up-to-date.
pi@pi /srv/src/wiringPi $

ビルドとインストール

pi@pi cd wiringPi
pi@pi ./build

ビルドスクリプトでバイナリが/usr/localにインストールされてしまうのが嫌．

動作確認

pi@pi /srv/src/wiringPi $ which gpio
/usr/local/bin/gpio
pi@pi /srv/src/wiringPi $ gpio -v
gpio version: 2.20
