FreeRADIUS Dependencies
Some external dependencies must be installed before building or
running FreeRADIUS. For version 3, the core depends on one
mandatory library: libtalloc
for memory management.
Many of the modules also have optional dependencies. For example, the LDAP module requires LDAP client libraries to be installed and database modules need their respective database client libraries.
If building from source code, the configure stage will check for the optional dependencies. Any missing libraries will cause that particular module to be skipped.
