Omitting the --prefix =3D/board-rfs, DESTDIR=3D/boar= d-rfs was passed in make install, and on checking, it seemed that the bin= , lib, share and include components of the alsa-lib were installed under = /board-rfs/usr

However on running an application, this is got <= br>
-bash-3.1# ./soundtest default
ALSA lib pcm_params.c:2152:(s= nd_pcm_hw_refine_slave) Slave PCM not usable
cannot initialize hardwa= re parameter structure (Invalid argument)

Setting the environmen= t variable $LIBASOUND_DEBUG to 1 does not cause any debugging information= to be displayed to stderr. (I double checked via #echo to make sure LIBA= SOUND_DEBUG was set to 1)

I'm clueless, am I doing anything wron= g ?

Thanks much,
iyer

B= ut --prefix=3DXXX overrides the path embedded in the code. For
instal= ling to another root, passing DESTDIR=3DXXX at make install is the

This is a different thing. Now the system files are properly set and=
alsa-lib reads them. But, the driver returns an error for the
required PCM setting.

Try to set $LIB= ASOUND_DEBUG to 1. Then each hw_params error will be
displayed to std= err. See alsa-lib/NOTES for details.
