Hi list, I hope this is the right area to ask, I'm trying to compile PDO support in 5.2.6 and am following the instructions here http://us2.php.net/manual/en/pdo.installation.php My compile line is the following ./configure --enable-force-cgi-redirect \ --disable-rpath \ --with-bz2 \ --with-db4=/usr \ --with-curl \ --with-gd \ --enable-gd-native-ttf \ --without-gdbm \ --with-gettext \ --with-ncurses \ --with-gmp \ --with-iconv \ --with-openssl \ --with-regex=system \ --with-zlib \ --with-layout=GNU \ --enable-bcmath \ --enable-exif \ --enable-ftp \ --enable-magic-quotes \ --enable-sockets \ --enable-sysvsem \ --enable-sysvshm \ --enable-wddx \ --with-kerberos \ --with-ldap=shared \ --with-mysql=shared \ --enable-mbstring=all \ --with-apxs2=/usr/sbin/apxs \ --with-pgsql=shared \ --with-mysqli \ --with-freetype-dir=/usr/include/freetype2 \ --with-mcrypt \ --enable-soap \ --enable-pcntl \ --enable-pdo=shared \ --with-sqlite=shared \ --with-pdo-sqlite=shared \ --with-pdo-mysql=shared \ --with-pdo-pgsql=shared \ --with-pdo-oci=shared This config line I'm working with has been a growing one, so there may be some things here that may or may not be needed. Anyway, Upon compiling the above, I get the following error when I do a php -m Warning: PHP Startup: Invalid library (maybe not a PHP library) 'pdo.so' in Unknown on line 0 Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/20060613/pdo_mysql.so' - /usr/local/lib/php/20060613/pdo_mysql.so: undefined symbol: php_pdo_get_dbh_ce in Unknown on line 0 Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/20060613/pdo_pgsql.so' - /usr/local/lib/php/20060613/pdo_pgsql.so: undefined symbol: php_pdo_register_driver in Unknown on line 0 Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/20060613/pdo_sqlite.so' - /usr/local/lib/php/20060613/pdo_sqlite.so: undefined symbol: php_pdo_register_driver in Unknown on line 0 Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/20060613/sqlite.so' - /usr/local/lib/php/20060613/sqlite.so: undefined symbol: php_pdo_register_driver in Unknown on line 0 I've included the extensions in my php.ini file, but I'm completely lost on where to go from here because the error is less than helpful. The order that I've included them is extension=pdo.so extension=pdo_mysql.so extension=pdo_pgsql.so extension=pdo_sqlite.so extension=sqlite.so and they do exist, as shown here -rwxr-xr-x 1 root root 364012 May 14 2007 apc.so -rwxr-xr-x 1 root root 102531 Aug 18 14:25 ldap.so -rwxr-xr-x 1 root root 120644 Aug 18 14:25 mysql.so -rwxr-xr-x 1 root root 270860 Nov 13 2006 oci8.so -rwxr-xr-x 1 root root 125246 Aug 18 14:25 pdo_mysql.so -rwxr-xr-x 1 root root 100772 Aug 18 14:25 pdo_oci.so -rwxr-xr-x 1 root root 111246 Aug 18 14:25 pdo_pgsql.so -rwxr-xr-x 1 root root 270276 Aug 18 14:25 pdo.so -rwxr-xr-x 1 root root 1370516 Aug 18 14:25 pdo_sqlite.so -rwxr-xr-x 1 root root 235943 Aug 18 14:25 pgsql.so -rwxr-xr-x 1 root root 1010437 Aug 18 14:25 sqlite.so -rwxr-xr-x 1 root root 598407 Jan 29 2008 xdebug.so I'm using RHEL 4, and have installed the sqlite-devel, but I think php is choosing to use the sqlite that comes with it???? I'm hoping someone on the list can point me in the right direction. Thanks in advance, Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
