Re: [SoX-users] Compiling Sox with mp3 support under cygwin

[Chris B. <ch...@cn...>]

It is some sort of libmad problem that I don't understand.  Probably
there is a compiler bug in your version of cygwin. A work
around may be to edit the libmad timer.c and layer3.c and add the
following to the top but after #includes:

#undef assert
#define assert(x)

Also, you can rerun SoX's configure with an --disable-mad option.  Then
you won't be able to read mp3 files but you can write them.  At least
you can then do some of your processing.
