Hi,

I have integrated the codec driver and the kernel log shows the sound
card is detected.
now i want to test the codec. i tried the sample test code for capture
and playback.

i am getting a compilation errors due to the asoundlib.h.
please find the error log for my application.

This means that alsa-lib is not installed correctly.

On Debian/Ubuntu, install a package called libasound2-dev
On SuSe, you can probably `zypper install -C 'pkgconfig(alsa)'` (I
think the -C is correct... for "capabilities")
On Fedora, it's `yum install 'pkgconfig(alsa)'`

I am still getting the problem even though alsa-lib-devel is installed on my 
fedora 14.

On Fedora 19 I get:

    $ pkg-config --cflags alsa
    -I/usr/include/alsa

So:

   1. Make sure that /usr/include/alsa/asoundlib.h exists
   2. Make sure that you add "-I/usr/include/alsa" to your CFLAGS
