[alsa-devel] Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_jack.so

[Srinivasan S]

Thanks a lot for your responses, I was eagerly waiting for your replies,

Am sorry, as am poor in alsa 

Could you please help me out in resolving this issue

root at lifeline:/# vi etc/asound.conf
pcm.rawjack {
type jack
playback_ports {
0 system:playback_1
1 system:playback_2
}
capture_ports {
0 system:capture_1
1 system:capture_2
}
}

pcm.jack {
type plug
slave { pcm "rawjack" }
hint {
description "JACK Audio Connection Kit"
}
}

pcm.!default {
type plug
slave { pcm "rawjack" }
}

root at lifeline:/opt/tunstall/audio# aplay -D pcm.jack TangoForTajMusic11.wav

Even I installed libasound2-dev in my linux host machine still the same issue

srinivasan at tata-HP-Elite-7100-Microtower-PC:~/alsa-plugins-1.0.29$ ./configure --prefix=/home/srinivasan/alsa-plugins-1.0.29/exes --host=arm-arago-linux-gnueabi

configure: error: Package requirements (alsa >= 1.0.11) were not met:

No package 'alsa' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables ALSA_CFLAGS
and ALSA_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

Am sorry I wrongly understood, where I get libasound_module_pcm_jack.so is it in alsa-lib?? or alsa-plugins??, I just blindly tried cross compiling alsa-plugins-1.0.29 with above errors, without cross compiling alsa-lib 1.0.27.2-r0, does this alsa lib version supports this library???

I have never cross_compiled alsa-lib 1.0.27.2-r0 am using the alsa-lib version which is provided in ti sdk 8 BSP's

Could you please help me out first how to cross_compile alsa-lib 1.0.27.2-r0 version??? & then alsa-plugins


Many Thanks in advance..

Well, did you cross-compile alsa-lib?
