Hi,
Ok,I see. Thanks for the quick reply.
I tried it interactively and the error looks the same:
...
sc3 s.boot;
booting 57110
localhost
sc3 Cannot connect to server socket err = Connection refused
Cannot connect to server socket
OK, I've tested this on a new install (on 32-bit rather than 64-bit,
but otherwise similar) and I definitely can't reproduce it. Here are
some reasons why the server might be unable to connect:
* There might already be a copy of scsynth running (e.g. from a
previous attempt) -- use top/htop to check, or use killall scsynth
before trying again.
* There might be some other service blocking the port (the port is
listed in the output, 57110) -- use netstat -a to check.
* There might be some firewall program running or suchlike, or some
unusual network configuration (e.g. no 'localhost')?
If any of them turn out to be what's happening for you, please let us
know. If anyone else can reproduce please tell us.
Thanks
Dan
I don't have any other scsynth processes, I have a working 'localhost'
and no firewall.
This bug was caused by Jackd. If yo have a sound chip that is unable
to do full-duplex audio, it just aborts with an assertion
('port_index fPortMax' failed). This is considered a reasonable
behavior for a sound server.
See Bug #646248.

Bug#644976: [supercollider] server fails to start
Hi -
Firstly, it is better to start jackd manually - that's what sc users
normally do, and in particular for bug reports it would be clearer
because jackd's startup procedure doesn't have to be included in the
output. (It should work, though.)
But the more fundamental issue is that booting the server is
asynchronous, so if you run a script which contains s.boot; s.quit;
the language doesn't wait for it to boot before it sends a quit
message. The tutorial you're reading is probably assuming interactive
use rather than a batch script. So I'd be grateful if you could either
test interactively, running something like:
s.boot;
// then wait for a happy boot message, then:
s.quit
or by using a script consisting of this:
s.waitForBoot{s.quit}
(The waitForBoot message is a convenience method that starts the boot
and then creates a Task which waits until booted before executing the
function.)
