encoder audio or speech for omap5912

[Michał Szabat]

Hello. 

I want encode wav to mp3 on omap5912. I try to compiled lame3.96.1 with toolchain3.4.1 with options 
CC=arm-linux-gcc ./configure --target=arm-linux --host=arm-linux --prefix=/root/lame. 
This compiled properly, but not works.  

/ # lame
LAME version 3.96.1 (http://lame.sourceforge.net/)

usage: lame [options] <infile> [outfile]

    <infile> and/or <outfile> can be "-", which means stdin/stdout.

Try:
     "lame --help"           for general usage information
 or:
     "lame --preset help"    for information on suggested predefined settings
 or:
     "lame --longhelp"
  or "lame -?"              for a complete options list
/home # lame xp.wav xp.mp3
Segmentation fault.

I think that the problem maybe with this(configure warning)

Anyone could help me with this. It not must be lame encoder. I tried with bladeenc and speex.

Hi All, 
 
I want encode wav to mp3 on omap5912. I try to compiled lame3.97 with

Maybe you should follow the advice the tool gives you?

OMAP is little endian. If you are unsure which sizes are 
correct for the various #define SIZEOF_xx try to write a 
short test program which does someting like

printf("Size of short: %i\n", sizeof(short));

etc.
