PHP Warning: PHP Startup: Unable to load dynamic library ‘/usr/local/lib/php/20090626/tokyo_tyrant.so’ – /usr/local/lib/php/20090626/tokyo_tyrant.so: Undefined symbol “ps_globals” in Unknown on line 0

Every time I upgrade the PHP and related extensions, I always run into the same problem with some PHP-PECL modules. Recently with the new release of PHP 5.3.7, there is no exception for the trouble. So what kind of trouble I have today? The Tokyo Tyrant (The middleman between my program and Tokyo Cabinet).

#php -v

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/lib/php/20090626/tokyo_tyrant.so' - /usr/local/lib/php/20090626/tokyo_tyrant.so: Undefined symbol "ps_globals" in Unknown on line 0

This problem was caused by a version mis-match. PHP is running at a later version, which the Tokyo Tyrant extension is running at an earlier version. To solve this computer problem, all you need is to re-install the PHP-Tokyo-Tyrant extension, i.e.,

cd /usr/ports/databases/pecl-tokyo_tyrant
suod make deinstall clean
sudo make install

And later, you may or may not get the following error message:

...
cc -shared  .libs/tokyo_tyrant.o .libs/tokyo_tyrant_funcs.o .libs/connection.o .libs/session_funcs.o .libs/server_pool.o .libs/failover.o .libs/session.o  -Wl,--rpath -Wl,/usr/local/lib -Wl,--rpath -Wl,/usr/local/lib -L/usr/local/lib -ltokyotyrant -llua -ltokyocabinet /usr/local/lib/liblzo2.so -llzma -lbz2 -lz -lrt -lm  -Wl,-soname -Wl,tokyo_tyrant.so -o ./.libs/tokyo_tyrant.so
/usr/bin/ld: cannot find -llua
*** Error code 1

Stop in /usr/ports/databases/pecl-tokyo_tyrant/work/tokyo_tyrant-0.6.0.
*** Error code 1

Stop in /usr/ports/databases/pecl-tokyo_tyrant.

The problem is related to Lua. By default, the extension enable the Lua option, which I have a hard time to make it run properly on FreeBSD box. Since my website does not use the Lua with Tokyo Cabinet, I simply disable it:

sudo nano /usr/ports/databases/pecl-tokyo_tyrant/work/tokyo_tyrant-0.6.0/Make

Look for the keyword: lua
And you will find something like the following:

TOKYO_TYRANT_SHARED_LIBADD = -R/usr/local/lib -L/usr/local/lib -R/usr/local/lib -L/usr/local/lib -ltokyotyrant -llua -ltokyocabinet -lbz2 -lz -lrt -lm -ltokyocabinet -llzo2 -llzma -lbz2 -lz -lrt -lm

Delete the option: “-llua”, i.e.,

TOKYO_TYRANT_SHARED_LIBADD = -R/usr/local/lib -L/usr/local/lib -R/usr/local/lib -L/usr/local/lib -ltokyotyrant -ltokyocabinet -lbz2 -lz -lrt -lm -ltokyocabinet -llzo2 -llzma -lbz2 -lz -lrt -lm

and re-start the installation:

cd /usr/ports/databases/pecl-tokyo_tyrant
sudo make install clean

Now re-run the php, and you may see the following error:

#php -v

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/lib/php/20090626/tokyo_tyrant.so' - /usr/local/lib/php/20090626/tokyo_tyrant.so: Undefined symbol "ps_globals" in Unknown on line 0
Segmentation fault: 11

That’s because the Tokyo Tyrant module is placed at a wrong position in the PHP extension file. Edit the file:

sudo nano /usr/local/etc/php/extensions.ini

and move the following code to the END of the file (Yes, order does matter):

extension=tokyo_tyrant.so

And re-check your php:

#php -v

PHP 5.3.7 with Suhosin-Patch (cli) (built: Aug 23 2011 10:33:12)
Copyright (c) 1997-2011 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2011 Zend Technologies

Now everything is all set.

Unfortunately, you pretty much need to do the same thing every time when upgrading your PHP on FreeBSD box.
