Speex dev - Oct 2006 - fixed point AEC

Analog Devices sponsored a fixed point version for AEC which was posted early
this year, but it seems from the source code that the fft routines are still in
floating point. Is the port still not complete or am I missing something? Has
anyone out there ported speex AEC on RISC architecture? Please let me know.
   
  Thanks in advance,

There are two FFTs in Speex, one of which (kissfft) works in fixed-point
(and is enabled by default). The AEC works fine at least on Blackfin.

Thanks Jean, I missed that detail. 
   
  I have a few more compile errors if you could help me with it =>
   
  In function speex_echo_state_init in mdf.c I am getting error: "undefined
reference to exp". I don't see a fixed point implementation of
"exp". Can you point me to the correct files.
   
  I am using the following files from speex 1.2 beta1 =>
  mdf.c, math_approx.c, misc.c, fft_wrap.c, kiss_fft.c, config.h, speex_types.h,
speex_echo.h, arch.h  .
