[strongSwan] [Strongswan][Error] Loaded 0 Radius server configurations

I'm trying to create a secure tunnel between my mobile device (Android) and
a gateway (Linux box). I need an EAP-SIM based authentication with the
radius server. For this I compiled the strongswan library with
--enable-eap-sim, --enable-eap-sim-file and --enable-eap-radius options on
both the Android device and the gateway machine. However when I try ipsec
start --nofork on my gateway machine, the charon daemon starts with
following error messages:

moon at moon-gw:~/Desktop/strongswan-5.1.0$ sudo ipsec start --nofork

Why am I getting this error? I referred the mailing list archives for this
but could not get any specific help. Also when my android device tries to
initiate IKE exchanges with the gateway, the gateway throws an error
saying: *loading EAP_RADIUS method failed.*

Can some one please help me on this?

Below is the content of my *strongswan.conf* file:
# strongswan.conf - strongSwan configuration file
charon {
# number of worker threads in charon
threads = 16

# send strongswan vendor ID?
# send_vendor_id = yes
