(Also posted to comp.lang.php.) I upgraded PHP on my Fedora Linux server to 4.3.10 due to the recent security issue and phpMyAdmin stopped working. I realized after lots of debugging that I'd previously custom-compiled PHP to match my custom upgrade of MySQL to 4.1.7 from Fedora's development branch. When I let yum install the pre-built PHP update binary, it had the old MySQL libraries so it couldn't talk to the newer MySQL with the different character set support. I finally figured it out when I tried to connect to the DB from another host running a v3 MySQL and got this error: mysql: File '/usr/share/mysql/charsets/?.conf' not found (Errcode: 2) mysql: Character set '#33' is not a compiled character set and is not specified in the '/usr/share/mysql/charsets/Index' file
