How to install oracle instantclient and pdo_oci on ubuntu machine?

I need to install PDO_OCI in ubuntu machine, there is no default package that I could install with apt-get.

There are a lot of tutorials showing how to do it, but when I follow them, I have problems related to compilation (configure, make,...)

Here what I did:

1. I followed this Tutorial to install instant client

2. Install oci8

   pecl install oci8

   I get error:

   error: oci.h not found

3. Install PDO_OCI

   mkdir -p /tmp/pear/download/cd /tmp/pear/download/pecl download pdo_ociphpize./configure –with-pdo-oci=instantclient,/usr,11.2

   error:

   pdo_driver.h not found ...

Please do you have any serious tutorial that works perfectly on UBUNTU 12.04?
