Your PHP MySQL library version differs from your MySQL server version?

The message indicates that : You are using version 5.1.43 of MySQL server But that the library that's used by PHP to communicate with that server has been compiled to communicate with a version 5.0. X of MySQL In theory this should not cause any real problem : minor versions tend to be compatible ; but you might need to update the library that's used by PHP ; maybe some package like libmysql or something like that (I don't have a Debian machine) If you want to make that warning disappear (even if I'm not sure it could really cause any big problem) you'll have to update the PHP component that is used to communicate with MySQL Note : With the dependancies, it might not be that easy, actually, to upgrade just one package I would say that you'd have to update something like php5-mysql which means : apt-get install php5-mysql (According to this page amongst others -- to update a single package, your must use install ) If you are using aptitude and not apt-get... Not sure about the right option that you should use to update only one package ; still aptitude safe-upgrade should present you with a list of packages it will upgrade, which will allow you to decide whether or not you wish to continue But you said in a comment to another answer that Debian ships by default with MySQL 5.0 -- which means the "official" module for PHP is probably compiled against libmysql 5.0, and not libmysql 5.1 To solve that problem, you'll have to either : Find a repository that provides PHP (or, at least, the mysql extension) compiled against libmysql 5.1 Or re-compile PHP and/or the mysql extension against the version of libmysql that's currently used on your system -- i.e. Libmysql 5.1.

Try running sudo apt-get update mysql-client.

I don't think this would work. My mysql-client (running from the console) is up-to-date, I was asking about the MySQL module for PHP. The problem stems from the fact that Debian 5 ships with MySQL 5.0 by default, and this is the version of the MySQL library included with PHP 5.

According to man: "update is used to resynchronize the package index files from their sources", not to update a single package. – middus Mar 13 '10 at 11:49.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
