level plugin not loaded with current cvs

level plugin not loaded with current cvs

[Laurent Georget]

Hi!

I have made sometimes ago a level plugin for Alsa called ameter.
(it is there:
http://perso.club-internet.fr/lgeorget/ameter.html
)
It was working fine until I checked out alsa cvs, and installing it
(yesterday).
After recompiling/installing  ameter without getting errors, , I have
now the following message when  using it:

[l@localhost l]$ arecord -D ameter -v sound.wav
ALSA lib dlmisc.c:107:(snd_dlsym_verify) unable to verify version for
symbol _snd_pcm_scope_ameter_open
ALSA lib pcm_meter.c:742:(snd_pcm_meter_add_scope_conf) symbol
_snd_pcm_scope_ameter_open is not defined inside /usr/local/lib/libameter.so
arecord: main:462: audio open error: No such device or address

There is the same message when using the plugin with Glame, and also
with Abramo Bagnara original level plugin.
(I am using Mandrake 9.0)

I installed back 0.9rc6, and it works fine again.

Any idea highly welcomed!

Laurent

it's due to the check of snd_dlsym().
now pcm_meter.c uses the normal dlsym(), so it should work again on cvs.
please give a try.


ciao,
