[pulseaudio-discuss] /.libs/.libs/ gotcha

When running PA manually, you probably specify "-p $(pwd)/src/.libs". I
have started to get error messages from PulseAudio about this, but I
don't remember exactly when. Perhaps ltdl has recently been updated, or
The gotcha is: ltdl seems to add another ".libs" and tries it first. As
a result, we get a callback to bind_now_open with
"src/.libs/.libs/module.so", which we don't find and complain loudly.
Ltdl gladly accepts this and tries instead with "src/.libs/module.so",
I tried specifying "-p $(pwd)/src" instead, but that fails in another
way: the ".ifexists" command in our CLI does not add a ".libs" the way
ltdl does, so the result is fewer errors, but then, it only loads the
required modules, and prefers module-detect over module-udev-detect, e
g, which is quite broken.
Any thoughts on the topic? Should we add ".libs" too, when looking for
files in ".ifexists"?
Or should we lower the severity of not finding modules? Perhaps write
with debug severity instead, and do that regardless of if we loaded a
module or not?
