PHP 5.0 build errors

Hi, everybody After having inserted the MySQLnd driver (downloaded from MySQL.com), and having followed directions from INSTALL file, I get the following warning after configure: .. . . . . . . Notice: Following unknown configure options were used: --enable-mysqlnd Check './configure --help' for available options .. . . . . . . And then, after compiling, I got the following errors .. . . . . . . /root/lamp/php-5.2.6/ext/mysqli/mysqli_api.c: In function `mysqli_stmt_bind_param_do_bind': /root/lamp/php-5.2.6/ext/mysqli/mysqli_api.c:101: error: `gptr' undeclared (first use in this function) /root/lamp/php-5.2.6/ext/mysqli/mysqli_api.c:101: error: (Each undeclared identifier is reported only once /root/lamp/php-5.2.6/ext/mysqli/mysqli_api.c:101: error: for each function it appears in.) /root/lamp/php-5.2.6/ext/mysqli/mysqli_api.c: In function `zif_mysqli_stmt_execute': /root/lamp/php-5.2.6/ext/mysqli/mysqli_api.c:709: error: `gptr' undeclared (first use in this function) /root/lamp/php-5.2.6/ext/mysqli/mysqli_api.c:781:20: warning: extra tokens at end of #ifdef directive make: *** [ext/mysqli/mysqli_api.lo] Error 1 .. . . . . . . What is missing? Any help will be appreciated. Best regards, Marco A. Cruz -- Freedom is not a permission for chaos.
