freeradius 2.1.10 with oracle instantclient11.2

[Waqas Toor]

Dear Community,

I am trying to compile freeradius2.1.10 with oracle instantclient11.2
and having problems where it is not detecting oracle libraries and
header files. where the oracle home is /opt/instantclient_11_2
there are two steps that I am trying and both are failing.
a: standard compile
 # ./configure --with-experimental-modules
--with-oracle-include-dir=/opt/instantclient_11_2/sdk/include
--with-oracle-lib-dir=/opt/instantclient_11_2
--with-oracle-home-dir=/opt/instantclient_11_2
and getting this error

b: in freeradius-server-2.1.10/src/modules/rlm_sql/drivers/rlm_sql_oracle
changed the Makefile.in and setting
RLM_SQL_CFLAGS =  -I/opt/instantclient_11_2/sdk/include $(INCLTDL)
RLM_SQL_LIBS   = -L/opt/instantclient_11_2

and then make.

but still getting the error.

any pointers .

Thanks
