Also I've tried to run our application on default centos mysql5, but have some errors with sql queries. In our application used very big, long and difficult sql queries, and they don't work after updating to mysql5. I've tried to compile mysql4.1.22 and 4.1.20 by hand too, but also have errors. I've compiled with only options --prefix=/usr/local/mysql4 --exec-prefix=/usr/local/mysql4 All compiled ok, and works seems ok, but our application still not work correctly. I don't have ideas about this matter. May be some specific options required...I don't know. In the end, I've downloaded precompiled mysql 4.1.22 (http://dev.mysql.com/downloads/mysql/4.1.html#linux-x86-32bit-rpms) unpacked it to /usr/local/mysql4, made some changes in mysql4 startup script, started... and all seems working fine now :) .
