Hi All, we downloaded the source software freeradius 3.0.16 from: git clone https://github.com/FreeRADIUS/freeradius-server.git cd freeradius-server git checkout release_3_0_16 The OS is RHEL 7.4. We will use freeRadius with Oracle 12 DataBase. We compiled with this enviroment variable seting export LD_LIBRARY_PATH=/usr/lib/oracle/12.2/client64/lib:/usr/lib:/usr/lib64 export ORACLE_HOME=/usr/include/oracle/12.2/client64 We had this WARNING: configure: WARNING: securid headers not found.
