#47819 [Fbk-Opn]: Getting pdo_mysql.so: undefined symbol: mysqlnd_debug_init at startup
ID: 47819 User updated by: shahar dot e at zend dot com Reported By: shahar dot e at zend dot com -Status: Feedback +Status: Open Bug Type: PDO related Operating System: Linux i386 PHP Version: 5.3.0RC1 Assigned To: mysql New Comment: I just tried again with today's snapshot (php5.3-200903310830) and looks like it is fixed. I no longer get the message, and pdo_mysql is indeed loaded. Thanks! Previous Comments: [2009-03-30 14:48:56] shahar dot e at zend dot com This still happens with the latest snapshot you linked to. Here are the relevant parts from sapi/cli/php -i: PHP Version = 5.3.0RC2-dev System = Linux wintergreen 2.6.28-gentoo-r2 #1 PREEMPT Sun Mar 8 17:10:56 IST 2009 i686 Build Date = Mar 30 2009 17:42:20 Configure Command = './configure' '--disable-all' '--enable-pdo' '--with-pdo-mysql=shared,mysqlnd' '--enable-debug' Server API = Command Line Interface Debug Build = yes Thread Safety = disabled mysqlnd mysqlnd = enabled Version = mysqlnd 5.0.5-dev - 081106 - $Revision: 1.3.2.22 $ Command buffer size = 2048 Read buffer size = 32768 Collecting statistics = Yes Collecting memory statistics = No PDO PDO support = enabled [2009-03-30 14:06:49] johan...@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.3-latest.tar.gz For Windows: http://windows.php.net/snapshots/ I still didn't reproduce it but applied a patch with some guessing. Please try the snapshot and see whether it helps. [2009-03-30 13:15:58] johan...@php.net Ah, the debug piece is important, investigating ... [2009-03-30 11:59:05] shahar dot e at zend dot com Yes, I'm building PHP from scratch with the above mentioned configure command. I think that in order to reproduce this you need to add --enable-debug to your ./configure, as so (I just tried this): $ ./configure --disable-all --enable-pdo --with-pdo-mysql=shared,mysqlnd --enable-debug $ make $ sapi/cli/php -d extension_dir=modules/ -d extension=pdo_mysql.so -m PHP Warning: PHP Startup: Unable to load dynamic library 'modules/pdo_mysql.so' - modules/pdo_mysql.so: undefined symbol: mysqlnd_debug_init in Unknown on line 0 I assume that ext/mysqlnd/mysqlnd_debug.c needs to be added as a build dependency of pdo_mysql if --enable-debug is set, but I am not experienced enough with autoconf et al to figure this out exactly. Thanks, Shahar. [2009-03-30 11:14:13] johan...@php.net Are you loading the module into a PHP which has mysqlnd enabled? Usually mysqlnd is automatically activated once another extension using mysqlnd is being activated. I tried the following which worked: $ ./configure --disable-all --enable-pdo --with-pdo-mysql=shared,mysqlnd $ make $ sapi/cli/php -d extension_dir=modules/ -d extension=pdo_mysql.so -m The remainder of the comments for this report are too long.
