Asterisk configure options used?

Hi,

I am trying to build some extra modules for our PBX, which was recently migrated from trixbox to the FreePBX Distro (User Agent: FPBX-2.10.1(1.8.16.0) SDP Session Name: Asterisk PBX 1.8.16.0. Could someone provide the configure options used to build asterisk (1.8.16) so that I could built the extra modules?

Thanks in advance.

Regards.
