Hi all,
I'm trying to compile PHP 5.2.1 on my Ubuntu 6.10 server. I've
downloaded the source code from php.net and am running the following
"configure" command on it:

../configure --with-apxs2=/usr/bin/apxs2 --with-mysql
--with-informix=/opt/informix --enable-shared --enable-pdo=shared
--without-sqlite --without-pdo-sqlite --with-pdo-mysql=shared
--with-zlib --with-xml --with-pdo-informix=shared,/opt/informix

After doing this, then "make", I copy over the generated libphp5.so file
into my Apache extensions directory, add extension=pdo.so (and lines for
the PDO-MySQL/Informix extensions) into my php.ini and restart Apache. I
would expect to see PDO, PDO-MySQL and PDO-Informix listed in my
phpinfo() - but they don't appear.

So, I tried recompiling PHP but without any of the PDO extensions being
shared. This worked, and I could see PDO and PDO-MySQL in phpinfo(), but
not PDO-Informix. I've also tried doing a "make install" after the
"make" in both instances, but that didn't help either.

So, can anyone hazard a guess as to why none of the PDO extensions load
when compiled shared? I don't get any related error messages in the
Apache or System logs by the way....

Cheers,
Matt

This might or might not help, but I had this problem before when doing a
compile from source.
I solved it by checking the extension directory matched that of php.ini

Hi Hendri,
Many thanks - your reply prompted me to solve my problem. I recompiled
PHP explicitly saying where the php.ini file was located, made some
other minor changes, and it's all working fine. You have helped me fix a
problem that has had me struggling for some time now, so thank you again :-)

Cheers,
Matt
