Hello. I need to call fft (fast fourier transform) functions in my rtthreads. I found in the internet a packet of fft functions called FFTW which I've been using in normal linux without any problems. FFTW uses math functions so you must be link your programs with -lm, in addition to -lfftw. But when I try to call FFTW from rtthreads I get some problems. In inserting the module y get some unresolved symbols in functions like malloc, fflush, free, exit, stderr, stdout, fprintf, sprintf. Does this mean that FFTW can't be used in RTLinux? Anyway, I can get rid of those unresolved symbols by linking in de C library -lc. But I get some new unresolved symbols in --udivdi3, --umoddi3 and --moddi3 (this last one isn't new). How can I get rid of those? If the final conclusion is that I can't use FFTW in rtlinux, does anyone know about some pack of fft functions which will work?
Thanks in advance and best regards. Miguel. -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] -- For more information on Real-Time Linux see: http://www.rtlinux.org/
