[Speex-dev] How to compile speex on STM32F10xxx controller with arm-none-eabi-gcc

[qianchen]

Hi
I am cpmpile speex using arm-none-eabi-gcc. All files are from 
STM32F10xxx Speex library firmware provided by ST. The following files I 
using is under "STM32F10x_Speex_Lib/STM32/libspeex/gcc":
filters_cortexM3.h, filters_cortexM3.s, ltp_cortexM3.h, ltp_cortexM3.s, 
vq_cortexm3.s.

When files were compiled, many errors occurred: many functions are 
undefined, such as "filter_mem16".
The stasements is like this:

#ifndef OVERRIDE_FILTER_MEM16
void filter_mem16( ... )
{ ... }
#endif

But at the beginning:

#ifdef __GNUC__     /* GNU Compiler */
#define OVERRIDE_FILTER_MEM16
#define OVERRIDE_IIR_MEM16
#define OVERRIDE_FIR_MEM16
#include "filters_cortexM3.h"
#endif

What's wrong with it? Should i modify the files?
