I am trying to set up a old PHP version using Macports on Snow Leopard. I have installed sudo port install php52 +apache2 +mysql5-server with no problem when I then try to install php5-mysql I get the following error.
Error: php5-mysql 5.3.6 requires PHP 5.3.6 but you have PHP 5.2.17.
Error: Target org.macports.configure returned: incompatible PHP installation
Log for php5-mysql is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_php_php5-mysql/main.log
Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>
I have tried to search the MacPorts help although this has not been very helpful to me in finding anything that relates to my problem.
Find an older version of php5-mysql that works with your PHP version, which is 5.2.17. Otherwise you will always run into this problem.
This is also known as a package dependency. If you can not fullfil a dependency, the package can not be installed (well it probably could, but then it would not run, so the package manager refuses you to install that).
From the changelog of the mysqli package it does not look like that 5.2 is supported, but according to linked information it might have been in some older package.
