I tried that and it seems that you MUST link also this shared module
against the asound library:
g++ --shared -g -Wall -I. -I../include -I../../dam/include
-I../../utility/include -lasound -o ALSAHelper.so ALSAHelper.cc
^^^^^^^^
Otherwise the versioned symbol are not applied. Here is the correct nm
output:
[EMAIL PROTECTED]:~/src/1/svn.rocklinux-consulting.de/gsmp/trunk/lowlevel/src>
nm ALSAHelper.so | grep snd_pcm_hw_params_get_channels_max
U snd_pcm_hw_params_get_channels_max@@ALSA_0.9.0rc4
Have fun,
