The 'zombied' message from jack and the 'midi write error' from brighton
indicate that bristol, the engine, has ungracefully exit, most typically a
segfault. Depending on your shell and write permissions on the 'bin'
directory you may be able to do the following:
nowhiskey@murija2:~/software/nove/bristol/bristol-0.9.5/bin$ limit
coredumpsize unlimited
nowhiskey@murija2:~/software/nove/bristol/bristol-0.9.5/bin$ ./startBristol
-rhodes -jack
Now do whatever until the error occurs and if you now close the synth window
from the title bar you will get a core dump IF you have write permissions in
the current directory. If you do not want to have write permissions on the
bristol/bin directory then try the following:
nowhiskey@murija2:~/software/nove/bristol/bristol-0.9.5/bin$ cd /tmp
nowhiskey@murija2:/tmp$ ~/software/nove/bristol/bristol-0.9.5/startBristol
-rhodes -jack
The coredump as an enclosure, or the stack backtrace from GDB will help to
track down the cause of the problem.

Nick.

rhodes, and rhodes-bass arent working, segfault?
Not the first complaint about these algorithms failing. To test it you
minimally need read access to the whole tree where you installed and built
bristol so that you can read the memories, then use the startBristol
script in the bin directory: 'startBristol -rhodes'. That is supposed to
work, and if that is how you get segmentation faults then I could do with
the output from a gdb stack backtrace ('gdb <bristol> <core>' then type in
"backtrace", or a core file sent directly to me).
i looked now following your instructions, it is not a segfault, but
zombifying jack.
i did:
cd /software/nove/bristol/bristol-0.9.5/bin$
and then:
./startBristol -rhodes -jack
the roads piano appears, it is connected to jack, but trying to play the
keys, no sound, than short time after rhodes stops:

please give me a more precisely "howto" for using "gdb"
copy in to /usr/local/bin or /usr/local/lib, so that i can put some
menu-entries, so being able to start from menu?
Hm, this is the second request for an install operation. Can you not build
in the full path to the startBristol script, with options, as a menu
command? Is the issue here that libraries cannot be found due to root
permissions and security or that binaries cannot be found if the path is
not configured correctly?
this part i really dont understand, but i think it is a less problem, since
i can copy the hole build dir somewhere, and than make the different
menu-entries.
cheers,
doc
Kind regards,
nick.
