PS. Please CC me when you reply. :-)
Andras Simon:
What does /etc/security/limits.conf say?
My file has this line:
"@audio - memlock 25000000"
which gives me 2.5m of non-locked memory. (at least I think
that's what it means)
Try make clean before make. If that doesn't help,
what says "sh gen_setformat_c.sh"? And which version
of libsndfile do you have?
Thanks.
Andras Simon:
That's just buffer init. Weird! Perhaps you
are running out of memory?
I shouldn't:
[simon@zsuzsi jack_capture-0.9.31]$ free
total used free shared buffers cached
Mem: 2059296 1937596 121700 0 82608 628812
-/+ buffers/cache: 1226176 833120
Swap: 8193108 4812 8188296
Can you try this one:

?
Sure:

This is probably related to the bug above, where it didn't
find a legal soundformat, and thus couldn't open a new file
with libsndfile either.
Also, what
machine do you have? (/proc/cpu) There's some atomic
operations going on in the buffer init, maybe they are locking up.

I see the problem. The script can't find <libsndfile.h>
for some reason, although gcc obviously could find it
when compiling jack_capture.c.
I don't understand how that could happen, but I'll add
checks for these two problems in the program as soon as I have
time. Thanks for the helping out.

Oh, and you should set rtrprio much higher. 100 should
be enough. :-)
You should also add the line
@jackuser - nice -20
I also wonder which distibution you are using?
Normally, the realtime user is called "audio"...?

Okay, this leads me to believe the source of the problem is that
atomic lifo/fifo queuse might not work on x86_64. Can you
try this older version instead? It uses plain old ringbuffers.
