Compile Error When Building ALSA Application

Hello,

I am building an application using the ALSA library. Specifically, I
am using the PCM APIs. The problem I am observing is when I use GCC
(version 3.3.4) to compile my program I get the following error:

   "audAbstraction.c:893: error: storage size of `status' isn't known"

I have defined a variable called 'status' which is a structure of the
type "snd_pcm_status_t". This structure is defined in the file
'/usr/include/sound/pcm.h'. Further investigation showed that this
structure is an alias of the structure, "sndrv_pcm_status" defined in
the file, '/usr/include/sound/asound.h'. Consequently, I verified the
definition of the structure and found no issues -- all members were
properly defined and accounted for.

I am certain that my makefile contains the path to the above mentioned
header files (NOTE: I verified this by putting erroneous data in the
header files and observing the compiler error). I have searched the
Internet for discussions and possible solutions but have not been
successful in fixing the error myself.

Is there a reason why the "sndrv_pcm_status" structure cannot be
resolved? What other suggestions do you have?

I appreciate your time in investigating and answering my query.

Best regards,

Moe
