I copied the one I just built earlier when I built libasound.a. When in the same K5 folder as the tones program, it actually runs, but reports a playback open error (no such device or address), just like twobob's compile did on the K5 with its original libs.

I will try it on my K3 now WITH the .so file...

EDIT: No, same error on K3 as K5:
Code:

[root@kindle us]# ./tones Playback device is hw:0,0 Stream parameters are 44100Hz, S16_LE, 2 channels Sine wave rate is 440.0000Hz Using transfer method: write ALSA lib dlmisc.c:246:(snd1_dlobj_cache_get) symbol _snd_pcm_hw_open is not defined inside [builtin] Playback open error: No such device or address [root@kindle us]#

So with the libasound.so copied to the run folder, it runs a bit before bailing...

FYI, my CodeSourcery is "2010q1-202", which works great for my monolithic demos.

So, do I need to install an OLDER CodeSourcery then? Which one will build apps that run on 2.5.8 through 5.1.0 firmware? This mismatch is WHY I want a static linked app with no (uncommon) library dependencies. I do NOT want separate compiled versions for different kindle firmwares...

P.S. I built the latest alsa 1.0.25... Do I need a version older than 1.0.9 then? I do not enjoy dealing with this stuff, and this is supposed to be a HOBBY... It is so much easier to pipe STDOUT to aplay (but much less elegant).
