 'apt-get install puredata' took out jack2

well, i can assure you that i have both puredata (0.43.2-2) and
jackd2 (1.9.8~dfsg.4+20120529git007cdc37-1) installed.

you could try installing jackd2...

 
 Maybe there's something else going on because I get 'signalling
 watchdog' and nothing else when attempting to start Pd.

which version of puredata do you have installed?
$ apt-cache show puredata
which version of pd are you using?
$ which pd

 
 Same problem with jack.

even if you start jack before starting pd -jack?

it seems like you changed a component that readanysf~ depends on

chances are high, that this component is indeed gstreamer (esp. since

faad support via libfaad.0.dylib)
- - or re-compile readanysf~ (and/or ffmpeg/libav) to match your newly

check for errors on the Pd-console (and probably on the cmdline as well).
maybe your longer videos are simply using a an unsupported codec.

it indeicates that there are some problems when talking to your sound

if they only appear once or twice at startup, they may indicate a

 You just put txt-document somewhere in your web-site, then you just

 So maybe Processing has some browser in it.
 
 Anyway, the question is: can PD easily connect with servers and

sure.
have a look at mrpeach's [tcpclient] helppatch.

 
 Is there any way to make browser-interface in one city - able to

sure, just ask on a web-dev forum.

apart from that, you don't need a webserver/browser thingie in order

you see a forward declaration of a function defined by pd, but not
exposed through it's headers.

for older versions of Pd (0.43) most of those private functions will
definitely be _unavailable_ on w32 (where you have to explicitely
export symbols in order to make them available for other dlls; un*x is
a usually less strict about exporting symbols).
with 0.43 a number of those private functions have been marked as
exported, so they might work with w32 as well.

iemguts uses non-public functions quite a lot (hence it's power and name)

it's a feature.

[expr~] behaves the same on max/msp and Pd, and therefore inherits the
best of both worlds (e.g. using integers when a number looks like an
integer)

the biggest problem is, that Pd's text-atom conversion will save a
token that looks like a number and can be expressed without decimals
as something that looks like an integer. e.g. [f 60.000] will be
stored as [f 60].
this can be problematic with [expr], e.g. [expr 1000.0 / 60.0] will be
stored as [expr 1000 / 60], which will result in integer evaluation
and produce 16.
a workaround is to make the parser think that the number is really
something else (a symbol), e.g. [expr (1000.0 / 60.0)], which will
produce 16....

whether you use [iem_r] or [receive13] is probably only a matter of
taste (but i think that most of ext13's objects are not so important
nowadays; and d13b is not so active in Pd land any more)

 
 I've used those 2 objects a lot and thought they seemed pretty
 stable...
 

that's because the trivial case (where receiving data and changing
the receive label are completely independent of each other
(stackwise)) won't create much of a problem.

it's easy to implement a feature and suddenly end up with a bug. it's
even common. both [recevie13] and [iem_receive] have probably gone
this route.
however, it's incredibly harder to implement a feature where you know
beforehand that you will open a can of worms and you don't know yet
how to close it (properly). that's the route [r] has gone.

 I am trying out ubuntu for one of my systems and have the following
 issue.
 
 I am able to control the frame rate, autogain and several other 
 features of the PS3eye camera from GUVCViewer, but I cannot do it
 from GEM.

Gem won't (shan't) touch any settings of the device if it can help it.
so setting the framerate before you start Gem should get you somewhere.

furthermore, it should be possible to change some properties of the
camera even while Gem is capturing.

in the case of guvcview this might not work due to guvcview (which
tries to also _capture_ images and fails doing so), but tools that
only set properties should work ok.
i'd recomment something simple like v4l2-ctl (on debian this is
available in the v4l-utils package)

$ v4l2-ctl -d /dev/video0 -p 120


 Could anyone suggest a way of controlling the camera so that GEM
 can use higher frame rates?

nevertheless, setting the framerate is currently really missing in
Gem's v4l2 backend. please file a feature-request (for Gem!).

yes, i think there will be a 0.93.4 release somewhen pretty soon.

i (still) believe that john's bug can be closed now (whatever the issue
with the Pd-extended build might be).

@john: if you don't mind, would you care to check whether the 0.93
branch has the issue fixed as well (current commitish there is
6dedf323d28)? (note: you might need to remove the
abstractions/gemdefaultwindow.pd before being able to switch to that branch)


and i don't think that the osx 1 frame video playback is a show
stopper, in a sense that mpg playback on OSx has probably always had
this problem and afaict from the bug-report the problem does not appear
with other file formats (at least .mov)

 Hi folks,
 
 I'm building a 2 way system consisting of 2 way send and receive

 adjusting sliders here, can send back changed slider values once again
 through udpsend and OSC.
 
 I'm getting an error saying Packet size (5) is not a multiple of 4
 bytes: dropping packet.
 
 I understand that an OSC packet has to be 4 bytes long. So how do I do this?

OSC packets have to have a size that are a multiple of 4 (filling up
with zeros if necessary), so instead of 5 bytes it should be 8 bytes.

[packOSC] will always generate correctly sized packets (at least it does
for me).
for whatever reasons you are loosing some bytes somewhere, try to find
out where - could be a wrong usage of [udpsend], something on the
network transport (statefull firewall, but unlikely), something you do
after [udpreceive] before the [unpackOSC]...it's a bit hard to tell what
is going wrong without a (stripped down) patch

in theory, you open a terminal, cd into the directory containing the

 I am not sure on this one but I think that if Pd does not find as many
 physical (or jack) inputs or outputs it will warn you. When you do
 provide enough IO you can reconfigure Pd for the new values and it
 should work (if you cross your fingers).


you don't do it like this.
when using jack, you should only be using jack (while Pd can use
multiple devices, this is really means mutliple devices on _one_
audio backend, not multiple backends simultaneously; jack is one
backend; portaudio another backend; furthermore, i don't think multiple
outputs work on anything but linux/alsa)

having said all that, i don't really understand your question.
use jack as Pd's sole audio interface, and then use jack-pilot or
qJackCtrl to route 2 outputs of Pd to your soundcard and the others to
wherever.
there is no need to complicate things by doing the routing in jack, Pd,
audioox and whatnot, when jack can handle everything just fine.


 
 3. I want to have 8 channels from one adc~ and another 8 from the
 other. This means all 16 channels are meant for input. How then do I
 route output from pd to the speakers?

what's the audio output of Pd todo with the audio input of Pd?

it would be good if you could sketch what you really want to do, rather
than how to attempt to solve it.

afaics it is something like:
- - you want to have the output of iTunes (8 chnannels) and Spotify
(another 8 channels) go into Pd, let Pd do some processing on that and
send the output of Pd to the stereo output of your computer.
SO
- - startup jack
- - startup Pd with -jack -channels 16
- - connect the 1st two output channels of Pd to your soundcard in jackpilot
- - connect the 8 outputs of iTunes to the 1st 8 inputs of Pd in jackpilot
- - connect the 8 outputs of Spitify to the 2nd 8 inputs of Pd in jackpilot

- - in Pd, you will get the
signals from iTunes using [adc~ 1 2 3 4 5 6 7 8] and the
signals from iSpit using [adc~ 9 10 11 12 13 14 15 16]
- - whatever you send to [dac~ 1 2] will go out to your speakers.

 I've been trying to track down a seg fault I keep getting and I'm still

 This is the latest pd-extended 0.43.1 Beta CVS March 29 (today) running
 on Oneric 32 but. I have simplified my patch to a point it doesn't make
 sense anymore but I can still make it crash, so I figure that's what we
 need.
 
 Basically if you create a new patch then make the object [test99 1],
 then copy and paste that object, then change the 1 parameter to a 2 you
 get a seg fault most of the time. If not, creating a [test99 3] or
 [test99 4] should do it, again most of the time.
 
 It seems related with Gem but I'm not sure if it is a Gem bug. I tried
 the same Gem library with Pd vanilla and it didn't crash. On the other
 hand, it seems related to the [pix_image] object in test99. Also you
 need to have the parameters to get the patch to crash, even though the
 patch doesn't take parameters. (The original patch did take parameters.)
 
 Core dump has only this information: Program terminated with signal 11,
 Segmentation fault.
 #0  0x0111ac01 in gem::RTE::Outlet::send(std::string,
 std::vectorgem::any, std::allocatorgem::any ) () from
 /usr/lib/pd-extended/extra/Gem/Gem.pd_linux
 

if i'm not mistaken this has been recently fixed in Gem (around 21st of
march) and is related to threaded loading of images and deleting objects
while the load is still in process.

to avoid the problem you can do either of those:
- - upgrade to a new version of gem (there's a backport of the fix to the
(stable) 0.93 branch of Gem, though no official release has been made
yet, containing the fix)
- - avoid using threaded loading of images, e.g by sending the [thread 0(
message to [pix_image] before loading images.
- - avoid deleting a [pix_image] that has pending open requests

 If you are going to make changes to the midi device setup, i have two

 by adding them manually in the registry. it would be nice if you could
 add at least 4 devices from the dialog..

why 4?
(and not, say, 37?)

 as for your idea to automatically open a midi devices, guess it can be
 useful for people who have only one device, but as son as you connect an
 external midi device, most of the time you have also an internal midi
 playback on the soundcard and you don't know which one is first in
 windows' enumeration..

i'm also rather sceptical about auto-connection, esp. when based on

 I think that having something setup by default is more helpful than nothing, 
 as long as it doesn't cause problems.  Then for people who want to have it

 Yes, in scripts/ in pure-data SVN.  You're best bet for getting Gem to accept 
 the meta files is to submit them to the pd-gem tracker.  For this release of 
 Pd-extended 0.43, Gem is already imported into the pd-extended/0.43 branch in 
 SVN, so you can commit directly there.
 

while of course i have no problem with including a Gem-meta.pd, i think
i remember that there where problems related to that simplistic approach.

Gem (as is and will stay for the foreseeable future), is a
single-binary-multiple-object library.
adding a Gem-meta.pd will make [import Gem] search for and find
Gem/Gem-meta.pd and happily report the Gem libdir(!) to be loaded
while this is really not enough to make Gem do anything at all.
I assume that people will then complain that Gem is broken because it
doesn't work even though [import] reports it should, while really only
the import mechanism cannot deal with Gem's reality.

my suggestion to make the -meta.pd patches something like proper
__init__ thingies, allowing a library to bootstrap itself where
unfortunately turned down (i'm sure for good reasons).

so this is the reason why there is no Gem-meta.pd (yet).
if my assumptions above are not true or don't matter, i guess there is
no reason to not add it.

 I think that Gem/Gem.pd_linux comes before Gem/Gem-meta.pd in the list of 
 priorties.
 
 
 good to know, thanks for sharing.
 

so Gem now comes with Gem-meta.pd [1]

 Not at pd right now, but can you get around that using an independent

marcodsad-Xth-Sense-lib-5299660 seems to be like a github generated

i guess the best approach is to properly tag the release at github, then
download the zip extract it, rename the root-folder re-zip it with the

github#s download-tagged-versions feature is great but i don't think it

start Pd with -nogui.
this should work on virtually any platform (there was a bug once in some

even then, -nogui might have worked)

on w32, you might want to use the pd.com rather than the pd.exe.
at least Pd-vanilla comes with both, i don't know about PdX.

hmm, all those questions are not very Pd related.
you might want to try some XP and/or hardware forum.

last time i did an installation with w32, i seem to remember that i used

making Pd start automatically shouldn't be a big deal (autostart?)

 Why do you need to keep a MSVC edition, again ? You probably told me
 already, but I don't remember.

i think there are two things:
- - writing code that compiles on _both_ MSVC and gcc gives me a better
feeling of standard conformity.
people using only gcc tend to use gcc-specific extensions (which is ok
if you only ever intend your program to be compiled with gcc;
similarily, it is ok to make heavy use of msvc-specifics if you don't
care about gcc; i prefer code that makes few assumptions about the used
compiler)

 
 Are there libraries that people use with GEM that require MSVC and can't
 work with MinGW ?
 

unfortunately yes.
some of the proprietary video backends (NaturalPoint,...) only come with
c++-libraries compiled with msvc.
it doesn't help to say then don't support them, if your employer
bought already bought their system.

also the current implementation of the DirectShow backend is tied to MSVC.

again, a solution would be to use a C-wrapper for anything that involves

 Hello,
 
 I'd like to know opinions from experienced developers about the use of

 I'm planning to write a compact library with audio analysis functions,
 to be used with Pd in the first place, but meant to be portable to
 other real time dsp frameworks. This project will contain several
 routines which must share one interface to Pd, and C++ will be most
 convenient for it. I've used C and C++ for Pd classes before, and both
 seem to work properly and efficient. But I lack experience to know on
 beforehand if there is some disadvantage of using C++ for a reusable
 dsp library. This will be my first. Quite some dsp libs are written in
 C, even today. Is there good reason to refrain from C++'s conveniences
 for writing classes, and use C instead?

one problem with C++ is that name-mangling is different depending on
which compiler/linker you are using.
this basically means, that you cannot use your C++-library binary made
with g++ in an application/... build with e.g. M$VC.

note that you can avoid this, if you provide a public C API, and use
C++ only as an implementation detail (e.g. and pass classes around as
anonymous structs)

 Is there a way to get a slider to print all its propperties? This will be
 useful to create a tool that makes randomness to any slider for a
 percentage depending on the ranges it is already set to. I obviously know
 the ranges, but have a huge number of sliders and [knob] objects so it
 would be painful to try to get them all.
 Also, if such a method exists, the randomic thing I wanna do could be
 implemented to any object without having to look at ist propperties.
 
 Would appreciate help or leads to workitout.
 

how about: normalize all slider ranges between 0..1 and transform the
output to the desired range only afterwards?

i always thought, that the MIDI-based default scaling of sliders and the
like was a step back, and that being able to specify the range has
little gain (though of course i use it...)

on the low-level side, you get buffers of data from the socket.
[mrpeach/tcp*] passes these buffers into user-land as they are.
great!


theer's a  reason why [iemnet/tcp*] does it slightly differently (that
is: serialize the data):
- - explicitely break the false sense of security of the user, that tcp/ip
could be packet oriented; because from user experience (mainly roman's
netpd) it shows that you must take re-fragmentation into account if you
want to make a stable system. if you receive the stream as multi-byte
chunks the user therefore ought to serialize it manually.
- - for performance reasons, it is way more efficient to do the
serialization in C than in Pd.


]btw, you can turn off automatic serialization with [iemnet/tcp*, but i
would not advise to do so.

i think that's not the point.
according to _debian_ policy (and ubuntu is a debian derivative) [1],
there is a clear definition of what should Depend and what should only

and Recommends is for packages that would be found together with this

the package manager should install recommended packages unless
explicitely told so otherwise (e.g. the user _requested_ to use
--no-install-recommends).
i no of no package manager that _defaults_ to --no-install-recommends.
if you have found one and it is the default in oneiric, than i think you
found a bug in the package manager, so you should report a bug for that

i think (iirc max correctly), miller meant an additional argument to the

e.g. [0, 1 12 s( could ramp in 12secs, wherease [1, 0 12 d( would take

which version of Gem is that?
it could be that the builds are simply using an old version of Gem.

this error seems to indicate that you are lacking real time priviliges
(what's the content of your /etc/security/limits.d/audio.conf?)

 This one appears when I load a complex patch. It also crashes Pd:

 tk scaling is 1.3187954309449634

 pd_gui: pd process exited

you could try to produce a backtrace [1]

 Funnily, Pd+Jack works with the same patch - as long as I start Pd
 with alsa, and after loading the patch change the audio to jack.

which would indicate that your patch takes too long to load and jack
kicks out Pd

 Just wanted to point out that the package for wheezy (i386) has an unmet
 dependency: x-ttcidfont-conf

 After googling a bit it appears it has been removed..
 http://packages.qa.debian.org/x/x-ttcidfont-conf.html
 
 That package is there for Gem, as far as I know.  Do any Gem people know
 if we still need that package?


i don't know about this package.
i even had to look up, what it is supposed to do.
it's definitely not a thing that Gem depends on (in a sense, that Gem
itself could make use of it)

the only dependency of Gem that is related to fonts is ftgl, everything
else (including a font package that provides a _default_ font for Gem
text rendering) should never ever be a hard dependency.

so from my side, feel free to remove the dependency on this package.

 what to do next, just copy  replace in the installed Pd?

for instance.
you could also try to point Pd'd path to the location of the new Gem.dll

or open cmd, cd into the build directory and run pd.com from there.

 (of course i tried already: gem.dll couldn't load)

run with -verbose and see whether it searches at the right place.
is there some other output?
also try to run pd.com from cmd, and see whether something interesting
is printed to the console.


 
 btw isn't the imegjpeg plugin also needed for working with .jpg files?

obviously.
you should try to run the gem_imageJPEG.dll from the release besides the
new Gem.dll

unfortunately i noticed that the plugins are compiled with SSE2 enabled
as well. but since they don't use any SSE2 specific code (so the
binaries will only contain SSE2 code autogenerated by the compiler), i
hope that they will still be runnable under a PIII.
if not, i will have to start a compilation myself :-(

you should not.

lots of packages that were originally only available via
debian-multimedia are now in debian proper.

debian and debian-multimedia are not coordinated (nor associated) in any
way,  this basically means that if you add debian-multimedia to your
apt-sources you are asking for trouble.

this is why i have dumped d-m on all the computers i'm maintaining for
some time now.

if you really need it (i think, apart from some codecs, decent
dvd-authoring tools are still only available via d-m) you might try:

- - remove d-m from your apt-list
- - remove all (now obsolete) packages that you intalled from d-m
- - install debian's native multimedia packages (e.g. gem), without any
dependency hell
- - re-add d-m to your apt-list
- - use apt-pinning [1] to avoid installing d-m packages if not requested
explicitely.

 great iohannes, thanks.
 a few points:
 
 --
  afaik the P3 has MMX  SSE  SIMD, why take this out?

it does not come with SSE2 so you should take this out.

 
 --
  to get going i started with the git-clone
 
 git clone git://pd-gem.git.sourceforge.net/gitroot/pd-gem/Gem
 
 is this 93.3?

it is everything since Gem was checked into a public repository.
with an ordinary git clone you get the full history (in this case, back
to Gem-0.87 in 2002)

the default branch is master which is where current development is
going on (that is: it's unstable)
if you are feeling less adventurous, checkout the 0.93 branch which will
currently be 0.93.3 (+ some minor bugfixes that did not make it into a
0.93.4 release yet)

 
 --
  at a first try: m_pd.h   pthread.h  sched.h were missing in the
 git-clone;

no they are not missing.
they are not part of Gem, so they do not come with Gem.

 i took them from the pd sources (0.43).

you should remove those files from your Gem directory and instead add
the path to Pd to your additional include paths and additional
library paths in the project settings.

Gem make some guesses where it could find those headers, but since there
is no consistent install directory on w32 those guesses will more likely
be wrong than correct.

 
 --
  compiling only GEM gives a number of warnings. especially this one looks
 not right:
 
 ..\..\src\Gem\glew.cpp(247) : warning C4273: '__glewCopyTexSubImage3D' :
 inconsistent dll linkage
 d:\gem\src\gem\glew.h(12022) : see previous definition of
 '__glewCopyTexSubImage3D'
 
 because it's given 2000 times, for every code that has to be glew'd.
  i guess there is some parameter for Windows not ok, but which one where?

fortunately it is only a warning and not an error.
so you can safely ignore it (at least that's what i did the last few
years...)
afaik this should be fixed in the master branch (either in
commit:ba9e4623d61aff41 or in commit:69519ea2c27c8f1, some 10 days ago)

 
 --
 is it eventually possible to use the recompiled GEM-93.3 in combination
 with Pd-ext 42.5?

yes, there shouldn't be a problem.

the Gem that comes with PdX is not build for PdX: instead i turn on my
w32 build machine, create a binary (compiled against Pd-vanilla), and
upload it to gem.iem.at; hans then downloads it and includes it into the
Pd-extended installers.

 (still talking about Windows). i noticed before that GEM-93.3 needs a
 PthreadVC.dll which is not included in 42.5.

it's the pthread implementation used by Pd-vanilla.
you could either use that or change the linker to use the pthread
implementation used by PdX.

 hi,

 trying to build a Pd-ext without SSE2 for Windows.

 (i guess there's not an easier way to go)
 
 i got stuck in ./building-libs-on-mingw.sh

building Gem on mingw is _highly_ experimental and _only_ works with a
recent git checkout.

there is close to zero chance that you can compile an older version of
Gem (e.g. the latest and greatest stable release 0.93.3) with anything
but visualstudio.

even then it is a big nightmare to setup (at least for me who barely
uses w32 and/or it's development environment) - if you need anything but
the core functionality.

if you can live without font support and the plugins for image (image
loading, video loading, movie loading) acquisition work (they _might_
work on P3, but of course i never tested) or you can do without them, it
should be fairly easy to compile:
- - edit the file configNT.h (you should find that in your project
browser under Gem/config/ or Gem/Gem/ or Gem/Base/) by commenting out
all defines about FTGL (that's probably only one at the beginning of the
file)
- - open the solution file matching your compiler best (e.g.
./build/win-vs2008/Gem.sln should work if you have VisualStudio-2008; if
you have a newr IDE just pick the most recent and upgrade the project)
- - remove all libraries with ftgl or freetype in their name from the
project settings (linker input).
- - to turn off SSE2 support, go (again) to the project preferences, go
the C/C++|Preprocessor and remove __MMX__ and __SSE2__
- - under C/C++|Codegeneration disable SIMD extensions
- - recompile the Gem project (recompiling the entire solution most
likely won't work if you don't have the dependencies for all thos
plugins installed in the right places)

 not as far as i can see. (i use fresh copies)

 with a non-existing file.

oh indeed. that was the wrong bug report i mentioned. i wanted to refer
to #3471122 (GL: invalid enum in each frame); but if you are using a
recent version this should not be the problem

 
 or what does every time at a change in the rendering mean exactly?


 every time the content of the GEM-window should change

i assume that you mean, whenever you rotate/translate/scale/... an
object in the scene?
there are so many ways you can make he GEM-window change. to name a few:
- - whenever you destroy, create a gemwin
- - whenever you change global ligthing
- - whenever you move things in the 3d scene
- - whenever someone moves in front of the camera that is captured and
applied as a texture
- - 

those changes are very different and might hint at different problems.
no doubt it is very clear to you what you mean by the content should
change; however, it is not so clear to me, that's why i keep asking.

if you can provide a minimal patch that triggers the problem, this might
greatly improve my understanding.

 try to find the object that actually causes the error.
 you can use a [GEMglReportError] that will output a warning if an error
 was raised since the last time any instance of [GEMglReportError] was
 called (the error state is also reset inside [gemwin] during each
 render-cycle..which is what causes the message to appear)


 it's not clear to me how to use this object, there's no help.
 connecting the inlet with a loadbang causes Pd/GEM to quit immediately.
 leaving the object by itself, with a print on the first outlet, gives
 nothing.

right, sorry for that.
[GEMglReportError] should be part of the render-chain.

here's an example:

[gemhead]
|
[GEMglReportError]-[nbx\
|
[weirdobject]
|
[GEMglReportError]-[nbx\

where you suspect that [weirdobject] is the cause of the problem.
if this is true, every time [weirdobject] does something stupid (in
openGL world), the lower [GEMglReportError] will send a non-null error
code to it's right outlet.
the other (upper) [GEMglReportError] is needed to clear any previous
error (in case you have multiple objects doing stupid things)


if things are very weird, you might even use something like

[gemhead]
|
[t a  a   a]
|   |  |
[GEMglReportError]  |  [GEMglReportError]
|
[weirdobject]
|
[GEMglReportError]

 should i make a bug report on this? (i'm on Pd-ext 42.5 with GEM 92.3)

ahem, so which version of gem are you actually using?
the current stable release is 0.93.3, and i was under the impression
that you were using a fresh copy of Gem.

probably you should _not_ set anything. the default is to install

if you want Pd to install into /sr rather than /usr/local, you should
simply specify the prefix with --prefix=/usr

making more troubles than it solves.


anyhow; the first thing i would try is:
- - run ./configure without any arguments (regarding the installation place)
$ ./configure
- - install into a test destination
$ make install DESTDIR=/tmp/pd/

and then inspect the contents of /tmp/pd/ and see where the headers got
installed.


you could also directly try the make install DESTDIR=... trick, and
see where you told Pd to install with all your configure flags...


in the end, i suspect that you simply lack the priviliges to install

this of course depends on your definition of tidiness.
e.g. i wouldn't say that C++ code is more tidy/readable if the text was
neatly justified (as opposed to the usual left-alignedness).

nevertheless, in my conception of tidyness, Pd alignment is also more
important than in text-based languages.
i just want to propose that if the readability of your patche depends on
the alignedness of the 3rd outlet, you probably should break it down

ah, i think the Make.local is now obsolete, since [wiimote] switched to
autotools and configure will check whether your library supports the
low-speed stuff (by checking whether the cwiid_motionplus_mesg struct
has a low_speed member).

so, if you only get low-speed values (even if you move the wii fast!)
and you are sure that you have a proper libcwiid, then the only thing i
can think of is, that configure fails to find your version of cwiid.
do you, by chance, have installed another version of cwiid as well, so
configure gets confused?

please post the output of configure  make (use pastie.org if it's too big).

instead of connecting the 4th outlet of [part_info] directly to [color],
use it to trigger the generation of 3 random values, and feed those to
[color].

if you want the colors to be persistent (that is: a given particle will
have the _same_ random colors in 2 consecutive render cycles), you might
want to reset the random generator to a given seed for each render cycle.
a good time and place to do that would be the bang from a [t a b] right
before [part_info].

more interesting things could be acchieved by storing the random
values in a table (of size partnum) and read those values, starting at 0
for each render cycle (again: derived from the trigger [part_info]
receives) and incrementing the counter for each particle (derived from
the output of [part_info].

 Can't you download libquicktime1 from an older version of ubuntu and
 install it anyway ? But just the lib itself, not the «-dev» package.

do you rely on anything in libquicktime1 that is not present in
libquicktime2?
afaik, they are API compatible, so a simple recompile should be possible

 Yep, on Linux (I don't know on other OS)  you have to specify the path
 to your vera.ttf (by default) in file  path.

Gem always needs to find the truetype font in order to be able to render
a text. it will look for the default font vera.ttf in all search-paths
of Pd, including the the patch's home.

explicitely calling destructors is a bit vague in this context. you

explicitely call destructors on exit.

anyhow, i believe good practice depends on a number of factors; so you
cannot simply say that using CamelCase is good practice whereas using
hungarian notation is bad practice.

personally, i prefer if the program does call dtors on exit, since there
are a number of ressources that cannot be automatically freed by the
operating system due to their very nature. if your Pd-patch controls the

if you are asking how to _properly_ install a package without root

nature of properly installing a package means writing to parts of the
disk where unproviliged users are not allowed to write to. that's by design.

anyhow, in my personal experience not many packages will actually
execute any scripts in the pre-/postinstall process; e.g. of the 3600
packages installed on my system, only 1800 come with a postinst script.
of those, at least 900 are virtually the same and only call ldconfig
(after installing a library).

if the package in question indeed contains a preinst/postinst script,
you can extract that with
$ ar x pd.deb
$ tar xvzf control.tar.gz
