Hi Chris,
   Thanks for helping me out with the OpenAL compilation process.=)
I successfully compiled the libraries with arm-xscale-*gcc compilers and
transferred the libs to my GeoAmida Handheld.

There's still one issue here: when i run "openal-info" provided with the
API, it gives me the following error:

ALSA lib conf.c:2700:(snd_config_hooks_call) Cannot open shared library
libasound_module_conf_pulse.so
ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL hw:0
AL lib: alsa.c:995: control open (0): No such file or directory
ALSA lib conf.c:2700:(snd_config_hooks_call) Cannot open shared library
libasound_module_conf_pulse.so
ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL hw:0
AL lib: alsa.c:1063: control open (0): No such file or directory
ALSA lib conf.c:2700:(snd_config_hooks_call) Cannot open shared library
libasound_module_conf_pulse.so
ALSA lib pcm.c:2205:(snd_pcm_open_noupdate) Unknown PCM default

Can you help me out with this error? Do i have to upgrade/tweak
ALSA?:confused:


Thanks and Regards,
