Hi all, I have PMPD working in Pd Extended 0.39.3. However, when I upgrade to the latest Pd Ext - the [pmpd] object refuses  to load? I'm on OS X 10.6.8 though I've noticed the sae issue on Linux
All the best, Rich

Very good idea, thanks Roman!
Some difficulties I'm having:
- I don't know how to set the label of [cnv]... is it possible at all?
- (ATTN: Ivica) [hsl] seems to have the bounding box (?) miscalculated in
l2ork so it doesn't GOP when it's less than 2-3px from the border of the
parent canvas. Checked in Vanilla, it works as expected ([hsl] can be
placed to the very border and it will GOP).

Interesting indeed.
Actually, I don't need the label to send a bang any more, because [pmenu]
won't pop up when the click happens inside a subpatch, so I need to put the
triggering object in the toplevel. (I might still hide it under the GOP
BTW, is it theoretically possible for a GOP object to display a menu on the
toplevel (stretching over the GOP area of the subpatch where it is)? If
yes, I'd eventually try to hack the pmenu code.

hi again,

just saw this thread right after posting mine :

sorry for bothering

here is attached three small patches that make PD crash
raw_client and raw_server work well together
but when I try to connect more client (eg. 10 with 10_raw_client)
crash happens...

I realize that with iemnet's version of tcpclient/tcpserver,
if two client connect at the same time to server, only on receive data not
the other,
so I put a timeout to disconnect the client if no answer was received in a
certain time and then reconnect

i first make this with iemnet's tcpserver
and I got a SIGPIPE on the server side (see my previous post)
while I got SIGSEGV on the client side, here is the gdb backtrace :

[New Thread 0x7fff7bfff700 (LWP 4478)]

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fffc8ff9700 (LWP 4477)]
0x0000000000472963 in clock_set ()
(gdb) watchdog: signaling pd...

I think in the server side a
could help but I don't know where to put it (in tcpserver.c ? in
iemlnet_sender.c or somewhere else ?)

also I tested it with the mrpeach's version, it doesn't crash but the GUI
gdb doesn't tell anything, it continue to show thread creation and exiting

also I'm using iemnet's first because it has a [port( method to change the
binding port on the fly
and I made a rebinding routing to choose an available port in a certain
range both in server and in client side
to prenvent connection error if port is still used after a crash for example

I don't know how to go further with this,
But I really need a reliable server for some project and for now I just
have an headache :-)
please tell me how i can help fixing this (and please note that I don't
know anything on tcp communication...)



do it yourself

    Workshop "Bodynet - How to make a network of bodies?"

      *Call for Collaborators*

Call to collaborate in the project development of the *five selected 
for the workshop**within the European project *METABODY* 
<http://www.metabody.eu/> - */Media Embodiment T?khn? and Bridges of 

Projects deal with topics such as performances and their relationship 
with the body, heteronomativity or the blurry boundaries between reality 
and fiction through technology.

Free registration. Dealine: 23 july, 2013. Limited space.

Dates: July 24 -31, 2013.

      Collaborators' Profile

The call is open to the participation of anyone interested. However, due 
to the type of projects, we are looking also for profiles such as 
cultural minorities, anthropologists, sociologists, biologists (how to 
body networks operate in this and other societies and ecosystems), 
social workers or care specialists (body, means and functional 
diversity), hackers and developers (how to engage the body in a digital 
network based on the model of the Brain Talk Communities).
