PHP and Sybase

Hello, I would like to make a connection to a sybase database in PHP. I installed freetds version 0.60 and it work fine (i can connect to a sybase database). Then, i compile the sybase extension (with php-devel) : $ phpize $ ./configure --with-php-configure=/usr/bin/php-config --with-sybas=/usr/local/freetds $ make $ make install I get the library php_sybase_db.so. I had a line in the php.ini file and i restart apache ($ apachectl restart) But when apache restart, i get an error: httpd : error while loading shared libraries :usr/lib/php/extensions/php_syabse_db.so undefined symbol : dbinit. I found this in the comments on sybase : If you compile php with freetds (www.freetds.org <http://www.freetds.org>) support (--with-sybase in php), apache might NOT START due to unresolved symbol. This can be easily solved by adding -ltds flag in config_vars.mk file after configuring PHP under the line EXTRA_LIBS. You can view this debug fix on www.freetds.org <http://www.freetds.org> under FAQ section. But i don't know where to add the option -ltds in config_vars.mk file. Could you help me Thank by advance.
