I'm getting errors when I call snd_seq_open in a plugin, which go away in a standalone
test app:
ALSA lib dlmisc.c:100:(snd_dlsym_verify) unable to verify version for symbol
snd_config_hook_load
ALSA lib conf.c:2655:(snd_config_hooks_call) symbol snd_config_hook_load is not defined
inside (null)
ALSA lib conf.c:3066:(snd_config_update_r) hooks failed, removing configuration
calling: snd_seq_open(&seq_handle, "default", SND_SEQ_OPEN_INPUT, 0)
What could be the reason for this?
cheers,
dave

I seem to remember having to pass a RTLD_GLOBAL flag to the dlopen call
that loads your plugin. Not sure of the exact details, but that flag
causes the symbols of subsequently loaded libraries to become global
(which is necessary for alsalib). Cheers.

it's a bug on 0.9.0rc6.
could you try the cvs version of alsa-lib?
thanks,
