Hello! I installed FR in my CentOS 6.2 from source. Doing a radtest on it, works good with files authentication. I try to change the authentication to sql mode, and I get the following error when I start FR: Thu Feb 2 11:30:36 2012 : Error: Could not link driver rlm_sql_postgresql: rlm_sql_postgresql.so: cannot open shared object file: No such file or directory Thu Feb 2 11:30:36 2012 : Error: Make sure it (and all its dependent libraries!) are in the search path of your system's ld. Thu Feb 2 11:30:36 2012 : Error: /netnfork/radius-server//etc/raddb/sql.conf[22]: Instantiation failed for module "sql" Thu Feb 2 11:30:36 2012 : Error: /netnfork/radius-server//etc/raddb/sites-enabled/default[177]: Failed to load module "sql". Thu Feb 2 11:30:36 2012 : Error: /netnfork/radius-server//etc/raddb/sites-enabled/default[69]: Errors parsing authorize section. When I installed the FR, I put a --prefix=/my/path to the ./configure command. The resulted warnings, that are related to my problem, are: ... configure: WARNING: silently not building rlm_sql_postgresql. configure: WARNING: FAILURE: rlm_sql_postgresql requires: libpq-fe.h libpq. ... I want to use FR with postgresql, and I have postgresql installed on my system, and also the FR database is already well done. (I know that because I have a FR installation under the default location. I installed it via yum, and it works good). So, can anybody explain me how to resolve my issue? I tried to install libpq-fe.h, but I didn't find it. I also tried to run the following: # ./configure --prefix=/my/path/ --with-postgresql-include-dir=/usr/pgsql-9.1/lib/ | grep -i WARNING but with the same WARNING. Can anybody help me on this?
