Two options:
1) Set the link order in your project such that fastrts gets linked
before rts. Since you're using BIOS I think the way you would do this
would be to create your own linker command file with a single inclusion
of the library and then inclusion of the auto-generated header file.
2) Use the alternate symbol. For example a single precision cosine is
the function cosf(float z). The _cosf symbol is part of both rts.lib
and fastrts.lib. The fastrts library gives you a second unique way to
call this function, cossp(float z). The _cossp symbol is only part of
fastrts.lib and resolves to the same code as _cosf in that library.

Hi
I am trying to make fasrts work on my TMS320DM642. I am using DSP/BIOS for
my program, and when I link rts6400.lib, and error appears saying that some
symbols (2) are defined multiple times (-c_int00 and __stack).
When i don't link the rts6400.lib and still include fasrts64x.lib, the
program compiles but fasrts functions aren't used and there are no
improvements for my computation time.
I already tried linking fasrts and rts6400 in the correct order, without
dsp/bios and i can see the effects of the library however i need DSP/BIOS.
Does anyone have an idea what to do?
Thanks
