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

[\x11]

Hi all:

        I just upgraded my bluez from 3.22 to 3.23.
        My ./configure param is like this:
bluez-libs-3.23:
./configure --host=3Darm-linux --prefix=3D/bluetooth
bluez-utils-3.23:
./configure --host=3Darm-linux --prefix=3D/bluetooth/ --enable-test --enabl=
e-usb --enable-input --enable-serial --enable-initscripts --enable-bccmd --=
enable-cups --disable-pcmia --enable-alsa --enable-audio --enable-shared PK=
G_CONFIG=3Dpkg-config --enable-obex --enable-avctrl --enable-network --enab=
le-debug

        A2DP works fine on 3.22.But I got the following error when i tried =
to play a2dp using "aplay -D bluetooth" in the 3.23:
        =

/ $ aplay -D bluetooth /tmp/1.wav
     ALSA lib pcm.c:2106:(snd_pcm_open_conf) Cannot open shared library /bl=
uetooth//lib/alsa-lib/libasound_module_pcm_bluetooth.so
aplay: main:546: audio open error: No such file or directory


BTW, my "libasound_module_pcm_bluetooth.so" is always in /bluetooth/lib/als=
a-lib , not /lib/alsa-lib . Because my '--prefix' is /bluetooth.

Is there anything wrong in my param of ./configure ?  Or something else is =
causing the issue?





Thanks

Installing in /bluetooth/lib/alsa-lib will not going to work, the same
applies to gstreamer plugin it must be installed in the prefix that
the application will load its plugins. You can either install the alsa
and gstreamer binaries in /bluetooth or change your prefix.

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

[\x11]

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

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

[\x11]

Problem solved.

from bluez 3.23 on ,  librt.so  is required .


But there's no related error information when i used "aplay -D bluetooth".

So i used strace and found why this "cannot open libasound_module_pcm_bluet=
ooth.so" error happened.
