Hello,
I am trying to compile sphinxbase for fixed point on windows.
I see three entries in sphinx_config.h file.
/ Default radix point for fixed-point /
/ #undef DEFAULT_RADIX /

/ Use Q15 fixed-point computation /
/ #undef FIXED16 /

/ Use fixed-point computation /
/ #undef FIXED_POINT /

Does it means that sphinxbase is by default compiled for fixed point
implementation on windows?

With regards
Pankaj

That means that default implementation is floating point. To compile fixed
point, turn undefs into defines:

define FIXED_POINT 1

Do we need to change all undefs to defines or just defining FIXED_POINT is
enough.
