Compiling PHP with MySQL

Question

Hello all,
I am having trouble compiling php 5.2 (also tried 5.3). This is my configure line:
=======
./configure with-apxs2=/usr/local/apache2/bin/apxs with-mysql=/opt/mysql/mysql
=======
When I run "make", I get the following error:
=======
Undefined first referenced
symbol in file
mysql_set_character_set ext/mysql/php_mysql.o
ld: fatal: Symbol referencing errors. No output written to sapi/cli/php
collect2: ld returned 1 exit status
*** Error code 1
make: Fatal error: Command failed for target `sapi/cli/php'
=======
Here are my machine details:
=======
@[machine-name]-/usr/local/php5.2 # uname -a
SunOS [machine-name] 5.10 Generic_138889-03 i86pc i386 i86pc Solaris
@[machine-name]-/usr/local/php5.2 # isainfo -kv
64-bit amd64 kernel modules
=======
PHP compiles fine when I do it without MySQL. Any assistance is greatly appreciated.
Please let me know if you need additional information.
Thank you.

Hi,
first of all please mind that PHP 5.2 is out of support by the PHP developers on php.net. To receive bug fixes petc. you should use PHP 5.3.
Secondly it is worth noticing that there are three function libraries (extensions) which allow accessing the MySQL database. One is the classic "mysql" extension, one is called mysqli, with "i" as in improved, and a driver for the PDO database abstraction - PDO_mysql. You are only activating one of these, in most situations you want all three of them gor maximum application compatibility.
Now with PHP 5.3 PHP bundles an implementation complete of the MySQL Client functionality. So linking against a local installation is not needed. This implementation is called mysqlnd - MySQL native driver.
To build w/ mysqlnd and all three function libraries use a configure line like this:
./configure with-apxs2=/usr/local/apache2/bin/apxs with-mysql=mysqlnd with-mysqli=mysqlnd with-pdo-mysql=mysqlnd
If you have a strong reason for 5.2 or using libmysql I'd need more information, like which version of mysql was installed. Was it self-compiled or binaries from mysql.com etc. But I hope the above is fine.
