facing problem in gas format conversion

Note: This was originally posted on 23rd June 2010 at http://forums.arm.com

Hi ,
I'm trying to cross-compile Openmax fft on linux platform using code sourcery.
I have started converting the whole set of files (Openmax fft for signal processing for RVDS 4.0) into "gas" format.
This is required because arm-gcc requires assembly files in gas format and openmax fft follows arm-cc format.
I'm facing with these errors.

undefined reference to `omxSP_FFTFwd_CToC_SC32_Sfs'
/openmax/bulid/../src/sigproc.c:481: undefined reference to `omxSP_FFTInv_CToC_SC32_Sfs'
sigproc.o: In function `SymTiming':
/openmax/bulid/../src/sigproc.c:603: undefined reference to `omxSP_FFTFwd_CToC_SC32_Sfs'
/openmax/bulid/../src/sigproc.c:647: undefined reference to `omxSP_FFTInv_CToC_SC32_Sfs'
sigproc.o: In function `FFT':
/openmax/bulid/../src/sigproc.c:809: undefined reference to `omxSP_FFTFwd_CToC_SC32_Sfs'

These functions are deifined in assembly file and I've included them into my make file.
I've also mentioned respective header file .
Any idea,where i'm missing.
Everything above works fine with RVDS 4.0 but not with code sourcery compiler.
Suggestions are welcome.
Thanks & Regards
