I am trying to static link alsa from source now, partially using instructions from here:
http://omappedia.org/wiki/ALSA_Setup

I need a libasound.a to static link my apps.

Hmm... Getting this error during this command:
arm-linux-gcc --static -o tones tones.c -lasound -lm -lpthread -ldl

Code:

warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

Apparently my libasound and libdl need different glibc versions than I am using now to static link them to the same app.

The reason I want static linking is so my app runs on firmware 2.5.8 through 5.1.0 kindles.

When I leave out the --static in the above command, it compiles. When running it on the K3 I get this error:
Code:

./tones: relocation error: ./tones: symbol snd_pcm_hw_params_set_rate_resample, version ALSA_1.0.9 not defined in file libasound.so.2 with link time reference

but when I run it on my K5 I get this error:
Code:

./tones: /usr/lib/libasound.so.2: version `ALSA_1.0.9' not found (required by ./tones)

What good is static linking if it still dynamically loads libraries? I read about an alsa patch to get real static linking. Now I will have to go track that down...

I get confused easily by these library version issues. That is one reason I like monolithic C programs with no library dependencies.
