Building the PHP extension on Unix and Mac OS X

You can build the PHP extension using the steps described here.

Prerequisites

The following is a list of software you must have on your system to build the PHP extension on Unix and Mac OS X:

The SQL Anywhere PHP extension source code. This code is included in the SQL Anywhere software install under sdk/php.
The PHP development package (php5-dev) which can be downloaded and installed from the PHP web site.

Context

You must have the same access privileges as the person who installed PHP to perform certain steps of the installation. Most Unix-based systems offer a sudo command that allows users with insufficient permissions to execute certain commands as a user with the right to execute them.

Procedure

Source the SQL Anywhere environment variables using one of the supplied scripts.
- Bourne shell and its derivatives
  Under Bourne shell and its derivatives, the name of this command is . (a single period). For example, if SQL Anywhere is installed in /opt/sqlanywhere17, the following statement sources sa_config.sh (use bin32 for 32-bit environments):
  . /opt/sqlanywhere17/bin64/sa_config.sh
  For example, on a Mac, run the following command to source sa_config.sh:
  . /Applications/SQLAnywhere17/System/bin64/sa_config.sh
- C-shell and its derivatives
  Under C-shell and its derivatives, the command is source. For example, if SQL Anywhere is installed in /opt/sqlanywhere17, the following command sources sa_config.csh (use bin32 for 32-bit environments):
  source /opt/sqlanywhere17/bin64/sa_config.csh
Change to the SQL Anywhere sdk/php directory containing the SQL Anywhere PHP extension software.

Build the extension using the following commands:

$ phpize
$ ./configure --with-sqlanywhere
$ make
$ make test
$ sudo make install

Edit the php.ini file in your PHP software install directory and make sure that the enable_dl option is enabled as follows.
```
enable_dl = On
```
Verify that PHP is aware of the extension by listing the contents of the PHP extensions directory and looking for sqlanywhere.so.
```
$ php -i | grep extension_dir
$ ls <extension_dir>
```

Results

If you are unsuccessful in building the PHP extension, keep track of the output of these commands and post it to the SQL Anywhere Forum for assistance.
