more pool weirdness, "double free or corruption"
by David NG McCallum 22 Sep '05

22 Sep '05

Thomas, Hope this isn't getting annoying yet. When I've used pool in a Pd session, if I try to quit Pd, the gui disappears, but the process still seems to be running. In the console I get: *** glibc detected *** pd: double free or corruption (fasttop): 0x08164048 *** pd_gui: pd process exited That number changes every time. I have to ctl-C in the console to get it to shut down. cheers, David -- __ _ _ _ _ __ ___ _ _ __ _ ___ ____ _ __ __ __ _ __ __ To talk about it is to miss the point http://sintheta.org

I forgot: Please do 'scons --help' to see possible puredata targets/options... Cheers, David -- # David Plans Casal problem.each { |day| assert_nil(spoon) }

Can you give me > some details on it? Hmm. Ok so I guess first of all, go look at: http://www.scons.org/doc/HTML/scons-user/book1.html Then, I guess that if you're doing the normal checkout with: cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/pure-data login checking out: cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/pure-data co -r devel_0_39 pd and updates like: cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/pure-data update -d I can assume that you will find the scons build scripts at: devel_0_39/src/SConscript Now, because the SConscript does platform detection like: if pdenv['PLATFORM'] == 'darwin': One can assume that all you have to do in theory is to type 'scons' at the command line. You will get output like: scons: Reading SConscript files ... Checking for dlopen() in C library dl... yes Checking for sin() in C library m... yes Checking for pthread_create() in C library pthread... yes Checking for main() in C library fftw3f... no scons: done reading SConscript files. scons: Building targets ... And then gcc will start doing its job. Scons is essentially a seriously easy and flexible software building framework scriptable in Python. At the end of it, you should get: scons: done building targets. If you do, it shouldn't be hard to add this to the existing bash script? As I said, I can help if welcome, and I'd love to see this bash script circulate. Cheers, David -- # David Plans Casal problem.each { |day| assert_nil(spoon) }

Re: [PD] pixelize in GEM
by Andrei R. Thomaz 22 Sep '05

hello wolfgand, bogart and list, 1) I couldn't use pix_resize several times: it works only once (that is, i would like to resize a image using two or more pix_resize objects) 2) I tried the pix_set and pix_dump solution, but I think my patch has some problemas. Please, give a look. thanks, andrei wolfgang schwarzenbrunner wrote: > hi... > > for a quiet rough pixelization you could use a pix_dump and pix_set > combination. > > regards > wolfgang > > At 13:49 22.09.2005, Andrei R.

pixelize in GEM
by Andrei R. Thomaz 22 Sep '05

22 Sep '05

hello list, is there an object that applies the pixelize effect to a pix_imagem, in gem? The object more close to that I found is pix_dot, but it isn't, exactly, what I am looking for. thanks, andrei -- RGB Design Digital www.rgbdesigndigital.com.br andrei(a)rgbdesigndigital.com.br / (51) 92067436

ann_som extern
by Jamie Bullock 22 Sep '05

22 Sep '05

Hi, This is probably a question for IOhannes. I have been doing some experiments with the ann_som external, and I have a few questions: - The output space is specified in two dimensions i.e. 8x8 or whatever, but the extern only has one output. Do I assume that this maps onto the output space something like 0-7 - row 1 left-to-right ... 56-63 left-to- right? - Do the Kohonen and Instar settings work? When I use these the output values just cluster around the maxima. Only when I use Outstar do I get proper self organisation. -- Regards, Jamie

vasp path for use with pd-0.38.4-extended-RC2
by Paris Treantafeles 22 Sep '05

22 Sep '05

Hi List, I'm running Hans-Christoph's pd-0.38.4-extended-RC2 on OSX. There are vasp files in /doc/vasp and in /doc/5.reference I've tried setting every path that I can think of so that vasp loads but am having no luck. Is there anyone out there running the same set up that can tell me what they are using in Path or Startup? Thanks, p

can i compile only this object as an external ? or do i have to compile the whole ggee ? or is there a .dll for windows somewhere ? would be cool ... i dont really want to get into cygwin. can i comile with bloodsheds dev-cpp ? its my current c/c++ compiler ... thx !

OSX, low latency and JACK [WAS: ... M-audio and pd asio problem]

Can anyone currently using PD for low latency audio on OSX follow up on this? I'd like to know if anyone has done any "speed tests" between Linux with ALSA and with JACK compared to OSX with Portaudio and with JACK. How much latency should I expect to lose from my HDSP, for example, if I run the same patches I normally use under Linux/JACK on OSX/Portaudio or OSX/JACK? Also if anyone has had difficulty/success compiling PD with JACK support on OSX, either Main or Devel branch. [Yes, BTW, I am thinking of getting a new computer! ;-) ] thx, derek -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 117: "Make it more sensual"

list-math: do math on lists
by Frank Barknecht 21 Sep '05

21 Sep '05

Hi, I figured, attached abstraction could be useful to someone else, too, even though it's very simple. list-math.pd will do basic math operations on lists, that is, add a constant to a list, multiply a list with a float etc. It is similar to Gem's vector operations v+, v*, etc. but is only using builtin objects (as of pd-0.39, where "list" was introduced) and can deal with mixed lists that also contain symbols, like "list a b c 1 2 3 x". The basic principle used inside can also be changed to do symbol operations or even more general ops. Just replace the central "expr" with something else.
