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

Hi Srini,

1. Can you run the aplay command with verbose output? It may give additional info to the log.

2. Do you actually have the libasound_module_pcm_jack.so in the usr/lib/alsa-lib directory?
You could try to cross compile it from its source and use the built libriary:
install libasound2-dev package
get the alsa-plugins tarball from http://www.alsa-project.org
extract the tarball somewhere
configure --prefix=/usr and make (you can even try make only in the jack subdir if the whole build fails)
manually copy the libasound_module_pcm_jack.la to /usr/lib/alsa-lib/
You can write to alsa community for support on cross-compiling the lib.

Best Regards,
Yordan

Dear Yordan,

Thanks a lot for your quick responses

1. Should I install libasound2-dev in linux host PC or in Am335x target??, If I need to install libasound2-dev in am3335x, could you please let me know how this can be installed

2. I have downloaded alsa-plugins-1.0.29 plugins, could you please provide the full command for cross compiling ie., configure --prefix=/usr & make, 

Could you please try to cross compile using configure --prefix=/usr once from your end & let me know, meanwhile I have posted to alsa community as well

Sorry to push you hard Yordan

Kindly do the needful as early as possible

Many Thanks in advance

Thanks

Dear Yordan,

Could you please help me out first how do I cross_compile any alsa-lib

Awaiting for your replies,

Thanks in advance

Hi Srini,

Sorry for the delay.

The procedure is:
1. cd /my/path/where/i/keep/my/source/code/
2. download and extract alsa sources
3. cd alsa-lib-VERSION/
4. ./configure --host=arm-unknown-linux-gnueabi --prefix=/my/path/were/i/keep/built/arm/stuff
5. make
6. make install

In step 4 you can use also --host & --target options, i.e.: -target=arm-linux --host=i686-linux

Hope this helps.

Best Regards,
Yordan

Dear Yordan,

Thanks a lot for all your responses & appreciate the same for your support w.r.t this thread

Dear Yordan,

I got some more inputs from alsa community, could you please help me out in resolving this issue,

Could you please retry cross compiling alsa-lib & let me know, meanwhile even I will try cross compiling & will keep you updated

That pkg-config does not know about "alsa". Apparently, TI's SDK did
not install alsa.pc together with the rest of alsa-lib.

Report this bug to TI.

As a workaround, try cross-compiling alsa-lib yourself.

Kindly do the needful as early as possible

Many Thanks in advance,

Have you tried compiling with bitbake?
