Install and configure OAuth in Ubuntu

First of all you need to make sure you already have php-pear and php5-dev.

If you are unsure just run

1	sudo apt-get install php-pear php5-dev make

now run

1	sudo pecl install oauth

Personnaly I had an error while compiling

1	/usr/include/php5/ext/pcre/php_pcre.h:29: fatal error: pcre.h:

To fix that just install : libpcre3-dev

1	sudo apt-get install libpcre3-dev

Once it’s done just add extension=oauth.so at the end of your php.ini (located in /etc/php5/apache2/php.ini) file and restart Apache.
