public at grik dot net,

the issue is when building the extensions shared we can't decide what to do 
with mysqlnd, should that be built-in or shared, too? Or maybe the user has a 
different mysqlnd? - We leave this to the user.

Johannes, thanks for the response, but according to 
http://php.net/ChangeLog-5.php
"ext/mysql, mysqli and pdo_mysql now use mysqlnd by default." in 5.4

So the issues are:
1. Why should we explicitly enable the feature used by default?
2. How can we NOT use mysqlnd in debug mode, if it issues an error for missing 
mysqlnd_debug_std_no_trace_funcs?

Hi,

the package is going to build with mysqlnd by default:

# cd /usr/ports/databases/php5-pdo_mysql && make config

MYSQLND - Use MySQL Native Driver (Is selected by default)

# make install clean

After installation:

The following line has been added to your /usr/local/etc/php/extensions.ini
configuration file to automatically load the installed extension:

extension=pdo_mysql.so

So the extension sholud be loaded after restarting php.

When building the MySQL extensions you explicitly have to enable mysqlnd. i.e. 
--enable-mysqlnd=shared. If you build mysqlnd shared you have to remember to 
load it, too.

I will look whether the build system can be made smarter and at least warn. I 
don't want to make the decision in there whether to build shared or static. If 
I'd make that decision I'd default to static mysqlnd.

# cd /usr/ports/database/php5-pdo_mysql && make install clean
