lib version?

lib version?

[Steve deRosier]

Ok, here's my stupid question of the day:

Is there any way for a program to query the alsa-lib to determine the version number?  Ie...  Assuming I'm using the relase of alsa-lib-1.0.4, I'd like to query and get back something that would indicate that I'm using that release (and I don't even care so much if my program is what queries it, I just need some way to figure what version the libasound.so.2.0.0 file is).

Basically here's the senerio I've got:
We've been developing a box for quite a while using alsa, and we've gone through regular upgrades of alsa on each release.   Unfortunately I'm trying to track down a rather serious problem in my client program, but I'm getting stymied due to what I suspect is a library version mismatch.  I got my program hacked up and working ok to a point and then it segfaults.  I replace libasound with a known 1.0.4 and it fails earlier in a different way (perhaps due to one of my hacks to get it working on whatever lib version I had in there).  I'm just trying to figure out why...  and knowing the library version # might get me there.

Any help would be appreciated.

Thanks,
- Steve

The function snd_asoundlib_version() won't be available before 1.0.5.
For earlier versions, you can try to test if the symbols listed in
alsa-lib/src/Versions are available.

On the Amiga all libraries had a version (mandatory by design) and
any file could contain a version string readable with the shell
command "version" just embedding a string with this format:
$VER: thingname v<major>.<minor><sub>
It was a very handy feature :)
