The build process is designed to work with PEAR (see » http://pear.php.net/ for more information about PEAR). There are two files that are used to assist in configuring your package for building. The first is config.m4 which is the autoconf configuration file for all platforms except Win32. The second is config.w32 which is a build configuration file for use on Win32. Skeleton files for these are built for you when you first set up your project. You then need to customize them to fit the needs of your project. Once you've customized your config files, you can build your driver using the following sequence of commands:
Before first build:
$ sudo pecl install PDO
For each build:
$ cd pdo_SKEL $ phpize $ ./configure $ make $ sudo make install
The process can then be repeated as necessary during the development process.
