I don't know whether this is a bug in ams, or a problem with my
system...I suspect the later, but can't figure out what's wrong.
But, I am unable to get ams to run. It appears to compile OK. But, as
noted below, running it results in a "Segmentation fault".
I have installed qt3 and fftw. I edited the top of make_ams to match my
system:
box1:~/audio_code/ams-1.5.5$ head -5 make_ams
QT_BASE_DIR=/usr/lib/qt3
QT_LIB_DIR=$(QT_BASE_DIR)/plugins-mt/styles
QT_BIN_DIR=/usr/bin
QT_INCLUDE_DIR=/usr/include/qt
X11_LIB_DIR=/usr/X11R6/lib
My ditribution is Debian stable (woody). My system is a PII 400Mhz
w/768MB RAM.
The version of g++ is 2.95.4.
I have a working install of jackd 0.44.0 from cvs. I'm starting jackd
like so:
# jackd -v -R -d alsa -d ymfpci -r 44100 -zt -n 3 -p 512
I can start up multiple instances of jack_metro, connect them to the
alsa ports and hear the beeps. So, jack appears to be working.
But, if I start ams nothing is reported in the jackd output about a new
client.
ams does attempt to connect to the X server when started. I know this
because if I 'su -' to get to root and then start ams:
box1:/home/eric/audio_code/ams-1.5.5# ./ams
ams: cannot connect to X server
but, if I su without the dash so that root inherits my user environment
ams gets past the point of connecting to the X server (assuming that
comes first) and exits with a segmentation fault.
I'm not sure what other information would be useful to you in helping me
to sort this out. If there is anything else I should tell you, please
let me know.
Thanks in advance,
Eric Rz.

hmm... I perhaps spoke too soon.
I had ams working yesterday on one box (at the office)... But, now I
can't seem to get it working at home. It seems to compile fine, but when
i try to start it:
box1:/home/eric/audio_code/ams-1.5.5# ./ams
Segmentation fault
box1:/home/eric/audio_code/ams-1.5.5# ./ams -j
Segmentation fault
It doesn't matter if jackd is running or not. Either way it seg
faults...
What could cause this?
What information should I provide to help sort this out?
Thanks,
Eric Rz.
