[En-Nut-Discussion] Problem in MMC MP3 Player wiki example

[André Aureliano]

Hi,
When I try to build the application for AT91SAM7X_EK board appears this
error:

C:/ethernut-4.10/nutbld/liblibcontrib.a(subband.o): In function
'xmp3_Subband':
subband.c:(.tet+0xac): undefined reference to 'xmp3_PolyphaseStereo'
subband.c:(.tet+0x114): undefined reference to 'xmp3_PolyphaseMono'

Can anyone help me. Thanks.
