Missing symbols in vm-sound-alsa, vm-sound-pulse

Philip Bernhart

I encountered with the cog.spur release 201901172323 that
the vm-sound-alsa and vm-sound-pulse plugins don't find
the respective symbols in the libraries when the relevant
system libraries are actually installed.

I get:

dlopen: sqcogspur64linux/lib/squeak/5.0-201901172323/vm-sound-pulse.so:
 undefined symbol: pa_simple_write                      

dlopen: sqcogspur64linux/lib/squeak/5.0-201901172323/vm-sound-ALSA.so:
undefined symbol: snd_mixer_selem_set_playback_switch_all                              

The interesting thing about that is that I have these libraries
installed and they contain these symbols:

$ strings /usr/lib/libasound.so | grep snd_mixer_selem_set_playback_switch_all

$ strings /usr/lib/libpulse-simple.so | grep pa_simple_write                    

Do you have any suggestions?
