Re: [Bluez-users] bluez 3.23 "cannot open libasound_module_pcm_bluetooth.so" issue on A2DP

["\x11" <semiyd@hotmail.com>]

Hi :
     I have to say i made a mistake in my former statement ;-) . Sorry for =
the inconvience...

     The situation is like this :
    =

     1.the prefix of bluez and alsa are both /bluetooth.
     2. Im using an embeded system which is running on NFS from my host com=
puter.   And "/bluetooth" is on my host computer and is the installation di=
rectory after i cross-compiled packeges like bluez/alsa.  The NFS on the ho=
st computer is actually "/work/rootfs" . So everytime i "make install " the=
 stuff into /bluetooth , i also have to copy things in /bluetooth into /wor=
k/rootfs so that my embeded system could use it as NFS.
     3. From my embeded system's point of view: After it mounted on NFS pro=
vided by the host computer,  the libasound_module_pcm_bluetooth.so is actua=
lly right there in /lib/alsa-lib.  And binaries like aplay is in /bin. I al=
so created a directory of /bluetooth and put some links into it .  Like thi=
s:

/bluetooth $ ls -l
lrwxrwxrwx 1 root root 4 Nov 12 2007 etc -> /etc
lrwxrwxrwx 1 root root 4 Nov 12 2007 lib -> /lib
lrwxrwxrwx 1 root root 6 Nov 12 2007 share -> /share
lrwxrwxrwx 1 root root 4 Nov 12 2007 usr -> /usr
lrwxrwxrwx 1 root root 4 Nov 12 2007 var -> /var

The reason im doing this is applications like aplay tends to search its plu=
gin libararies like libasound_module_pcm_bluetooth.so in /bluetooth/lib/als=
a-lib..

This method work fine before 3.23...
In 3.23, aplay turns out to say:
"Cannot open shared library /bluetooth//lib/alsa-lib/libasound_module_pcm_b=
luetooth.so"

Actually , maybe there's another clue.  If I replaced libasound_module_pcm_=
bluetooth.so with libraries of an older version like 3.22 in the same direc=
tory ,  the aplay no longer reports a "Cannot open shared library" error wh=
en i use aplay -D bluetooth. Although A2DP still can't work cause the versi=
on of the plugin lib is not right.


Anyway, sorry for any misunderstanding i caused. =

Could someone tell me what should i do now?



Thanks
