[PHP] segfault help
Hi list,
I'm getting a segfault when I run (what I assume) is a very simple
script. I'm not sure if it's a php bug or a bug in the library I'm
using (MDB2) with PHP 5.2.5 via the cli. Everything seems to go fine
until it's time for the script to end. That's when it receives the seg
fault.
I have the following backtrace.
Program received signal SIGSEGV, Segmentation fault.

(gdb) quit
The program is running. Exit anyway? (y or n) y
And it's occurring when I run this script
exec($query);
echo $count."\n";
$count++;
}
exit;
?>
appDB is my own wrapper around this code
$options = array(
'debug_expanded_output' => true,
'quote_identifier' => true,
);
$db = MDB2::singleton("sqlite:///myfile", $options);
$db->setFetchMode(MDB2_FETCHMODE_ASSOC);
$db->setOption('persistent', false);
As shown above, I'm using sqlite. The database file and the folder
that the file is in are both writable by the user that I'm running the
script as.
Any help would be appreciated.
Thanks,
Tim

Now, here's something weird, maybe someone can explain this. When compiled with --enable-debug, I don't see the "Segmentation fault" message on the cli. When I compile with --disable-debug, I see the error message. gdb too reports no error when debug is enabled. -Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] pdo compilation question
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.

[PHP] Pear File_Archive examples or _good_ documentation?
The authors site is unreachable so I cant check it for examples, but last I remember he didnt have very good examples to begin with. Does anyone, who's used this package have decent examples that showcase how to use it and use it well? In particular I'm looking for info on how to extract archives that meet the criteria below. - one folder with multiple items (including other folders) in it - multiple items(files or folders) at first level of the archive Reading the inline docs for the Pear class is less than useful for me because there's no concrete examples I can work off of...unless I'm blind and am completely missing something.
