Was making that much more difficult than it needed to be. Moved the asound libs to my staging directory and the program compiles to an executable...although with the two warnings: grhuser@pcL7:$ arm-linux-gcc -lasound -Wall -o grh_audio grh_audio.c grh_audio.c: In function 'grh_capture': grh_audio.c:112: warning: pointer targets in passing argument 3 of 'snd_pcm_hw_params_set_rate_near' differ in signedness grh_audio.c: In function 'grh_playback': grh_audio.c:207: warning: pointer targets in passing argument 3 of 'snd_pcm_hw_params_set_rate_near' differ in signedness Which comes from the code: 112: if ((err = snd_pcm_hw_params_set_rate_near (capture_handle, hw_params, &sample_rate, 0)) < 0) 207: if ((err = snd_pcm_hw_params_set_rate_near (playback_handle, hw_params, &sample_rate, 0)) < 0) I followed a piece of example code. I will look at this function to see if I can parse this warning out.
