I then decided to see what is going on with ladspa-rubberband.cat. I
found profound weirdness:
[jeb@youngdavid daw]$ file /usr/lib64/ladspa/ladspa-rubberband.cat
/usr/lib64/ladspa/ladspa-rubberband.cat: ASCII text
[jeb@youngdavid daw]$ cat /usr/lib64/ladspa/ladspa-rubberband.cat
ladspa:ladspa-rubberband:rubberband-pitchshifter-mono::Frequency > Pitch shifters
ladspa:ladspa-rubberband:rubberband-pitchshifter-stereo::Frequency > Pitch shifters
It is rather clear that non-mixer is trying to treat
/usr/lib64/ladspa/ladspa-rubberband.cat as a binary, looking for an ELF
header. It is just as clear, above, that the standard Fedora 13 file of
this name and location is an ASCII text configuration file of some kind,
not a binary at all.
Anyone know what should be done next?
Hmm. I don't think that /usr/lib64/ladspa/ladspa-rubberband.cat is
causing the error you are experiencing. As far as I understand,
non-mixer is browsing through each file in that directory, and
searching for a ladspa plugin. If it can't find something it spits a
warning. Just put some random file in there you will get another
warning. Or move the .cat file elsewhere, the warning will be gone.
Sorry, this is partly my fault because I read your initial message as
Warning: ... ladspa-rubberband.so rather than ladspa-rubberband.cat
I also get the same warning with the .cat file but after the
286 plugins found in 144 libraries
line, my mixer launches, and when I quit the application deliberately, I get
[non-mixer] Your fun is over
Your system quits the application unexpectedly. This will probably
need some debugging. I may have time to look into it next week, but it
would possibly be better to contact the actual developers.
I had plans to package non* stuff for Fedora, but I never had the time
to sit down and do it. It is, however, in our wishlist:
