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 & RegardsSuvir
Hi Suvir,I am trying to do a similar thing. Did you have any luck getting the RVDS converted for GNU compilers?Thanks!Jamie
try to make a .so from rvds and then link them on gcc..
I am doing this now, it used to work fine until I upgraded it, now it crash on link ...Can you suggest some flags that will be comptatible w/ armcc ones ?Related:http://forums.arm.co...ler/#entry36429http://stackoverflow...with-the-iphone
You can try ffmpeg fft.they are in GAS format , neon optimized and fine on cortex a8.
