Ok, I was able to execute the actual code, but I the output is not correct.
Here is what I did cat ~/data/audio/bfire-w2m.mp2 ./minimad > x.pcm I then encapsulate the PCM as a wave file with a program I wrote, and produced the file x-mni.wav
and I also did on the development linux machine. ./madplay --output=wave:x.-mp86.wav ~/data/audio/bfire-w2m.mp2
You can see that file size is different here: -rw-r--r-- 1 erojas users 37528 Sep 24 13:33 x-mini.wav -rw-r--r-- 1 erojas users 16172 Sep 24 13:36 x-mp86.wav
When I play these files on a PC using winamp the madplay produced file is correct, and the minimad produced file is white noisy.
Any ideas? Endianess? Number of bits per sample? It does output PCM?

Re: building madplay for the target, I'm having a devil of a time. Because I need to first install both the MAD library and tags library. But I can get the tags library to figure because it needs zlib. I have tried installing zlib, and I believe this has been done correctly, but the configure for the tags lib can not find it. I think this is because it is not telling the compiler to look in the right place, but I'm not really sure.
Re: script problem: The problem my be that I am installing the code in a directory that is later mounted as the root of the STB that I am developing for. I tried removing that part of the path in the one place it appeared and then executing it on the target but I still had the same error.
thanks, emil

Hmm, I still get this stuff when I try to run minimad, do have any idea what would cause that? I will make madplay and try it also.
I think it is probably because the minimad "executable" that is built is really only a shell script that invokes the real executable after first arranging to locate the correct shared libraries in the build environment (as they may not be installed yet).
The real executable lives in the .libs subdirectory.
