Postfix and Linux

Berkeley DB issues

Warning: if you can't compile Postfix because the file "db.h" isn't found, then you MUST install the Berkeley DB development package (name: db???-devel-???) that matches your system library. You can find out what is installed with the rpm command. For example:

$ rpm -qf /usr/lib/libdb.so
db4-4.3.29-2

This means that you need to install db4-devel-4.3.29-2 (on some systems, specify /lib/libdb.so in the rpm query).

DO NOT download some Berkeley DB version from the network. Every Postfix program will dump core when it is built with a different Berkeley DB version than the version that is used by the system library routines. See the DB_README file for further information.
