[Alsaplayer-devel] alsaplayer configure says "Build alsa 0.9.x output plugin: no"

[Timur Tabi]

I have a working ALSA driver on my system.  I downloaded the latest alsaplayer 
and when I ran ./configure, it says this:

   Build alsa 0.9.x output plugin:     no

I looked at the source code for configure, and I found this:

  if (eval "$ac_cpp conftest.$ac_ext") 2>&5 |
   $EGREP "AP_maGiC_VALUE" >/dev/null 2>&1; then
   have_alsa_final=yes

But I don't understand it.

What do I need to have in order to get alsaplayer to build ALSA output support?
