pd and gem compiling on osx10.4
by Peter Plessas 08 Feb '06

08 Feb '06

Dear List, after being away from osx for some time, i have now to install/compile pd on a 10.4 system, with tcltk 8.4.7 (tcltk-aqua). Compilation is fine, but at installing pd (in /usr/local) i get at launch: g4:/usr/local/bin peter$ ./pd sh: line 1: ../lib/pd/bin/../bin/pd: No such file or directory note that i start pd in /usr/local/bin. So the above path is definitely leading somewhere else.. I know it is unkommon to install pd there (on osx). Then i try to compile GemCVS (fresh checkout): g++ -c -fPIC -g -O2 -freg-struct-return -O3 -fno-builtin -falign-loops=16 -funroll-loops -ffast-math -faltivec -I.. TextBase.cpp -o TextBase.o g++ -c -fPIC -g -O2 -freg-struct-return -O3 -fno-builtin -falign-loops=16 -funroll-loops -ffast-math -faltivec -I.. glew.cpp -o glew.o glew.cpp: In function `void* NSGLGetProcAddress(const GLubyte*)': glew.cpp:78: error: invalid conversion from 'void*' to 'char*' g++ -c -fPIC -g -O2 -freg-struct-return -O3 -fno-builtin -falign-loops=16 -funroll-loops -ffast-math -faltivec -I.. sgiimage.cpp -o sgiimage.o make[1]: *** [glew.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make: *** [Base] Error 2 here the compiler version: g4:~/src/Gem/src peter$ gcc -v Reading specs from /usr/lib/gcc/powerpc-apple-darwin8/4.0.0/specs Configured with: /private/var/tmp/gcc/gcc-4061.obj~8/src/configure --disable-checking --prefix=/usr --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg][^+.-]*$/s/$/-4.0/ --with-gxx-include-dir=/include/gcc/darwin/4.0/c++ --build=powerpc-apple-darwin8 --host=powerpc-apple-darwin8 --target=powerpc-apple-darwin8 Thread model: posix gcc version 4.0.0 20041026 (Apple Computer, Inc. build 4061) Any help is very welcome!

signal continuity and filtering with block~ 2*N 2
by Charles Henry 07 Feb '06

07 Feb '06

I have been designing some externals for subband adaptive filtering, and I realized there was something wrong with my approach. I needed the block~ 2*N 2 inside a subpatch, to get a block of N new samples, while holding the N old samples for filtering. The actual filtering operation works on only the N new samples, leaving the N old samples the same. So, the thing is, I want to circumvent the addition of overlapping blocks, and have the output based only on the samples which have been filtered. I came up with one method, called reformat~, which does this: signal : | N old samples | N new samples | output: | N new samples | zeros--------------| It just moves N samples from the front to the back. This is resulting in clicking and brief cuts in the output. So far, I have coded all necessary parts, except the adaptation of filter coefficients. There may still be something wrong with the convolution routine, but (when not using reformat~) the signal shows good continuity and no clicks. Any thoughts? Suggestions? Chuck

Re: pd linux installer + gem
by Hans-Christoph Steiner 07 Feb '06

07 Feb '06

(let's keep this on the pd list since its of general interest) The linux Pd-extended package is newer, so its not as complete as the Mac OS X and Windows packages. Currently, the linux package does not include a Gem binary, but you can get one here: http://gem.iem.at .hc On Feb 7, 2006, at 6:18 AM, Davide Morelli wrote: > > hi Hans, > > yesterday i downlaoded and installed your packaged pd for linux > (ubuntu): > http://puredata.org/Members/hans/downloads/installers/Pd-0.38.4- > extended-RC7-linux-i686.tar.bz2 > but it can't find Gem.pd_linux > > is it normal that it is missing? > > ciao, > davide. > ________________________________________________________________________ ____ "[W]e have invented the technology to eliminate scarcity, but we are deliberately throwing it away to benefit those who profit from scarcity." -John Gilmore

GOP and GUI objects - bug? or desirable feature...
by Ed Kelly 07 Feb '06

07 Feb '06

Greetings all, I'm having a problem with the GOP function. Inside the patch I want to graph, I can move the GUIs about with [pos x y( messages, but when I look at it from the master patch, the GUI just vanishes or, worse still, moves to the right of the subpatch! I don't know if this could be called a bug, but it feels like one. Patch enclosed.

I wrote a little DVB reader and channel switcher this summer. As far as I know, once you have the drivers up and running, you will have some devices created under /dev/dvb/adapter0 If you have a decent card with hardware MPEG2 decoding, you will have an extra device there. If you have an el cheapo card like I do, without hardware decoding, you just get the mpeg2 stream under /dev/dvb/adapter0/dvr0 The first device I mentioned that is the decodec MPEG2 stream should be able to be opened like a v4l device (not sure about this though). The second device I mentioned, /dev/dvb/adapter0/dvr0, should be able to be opened as a regular mpeg2 file. Either way, you should be able to get it somehow into GEM or PDP. The difficult part will probably be to get your channels list and to switch channels without loosing sync. If you want some half-assed C++ code, let me know. best -august.

Re: definitions of data types
by Stefan Turner 06 Feb '06

06 Feb '06

Hi This is probably a pointless question as I guess by now it's far too difficult to change, and would definitely break a lot of patches...but wouldn't this all be easier if there weren't selectors? I.e. every element would be either a bang, a float, a pointer, or if it cannot be any of those, a symbol. Every message has a length of at least one, and if the length is two or greater, it is a list. E.g. [one 2 three< is a three-element list, where 'one' and 'three' are symbols, as they can't be anything else, and 2 is a float. [set table< is a two-symbol list. Obviously 'float', 'symbol', 'list' lose their special meanings and would all just be interpreted as symbols. Stefan ___________________________________________________________ Yahoo!

5DT Data Glove 5
by Sylvain 06 Feb '06

06 Feb '06

Hi all, Has anyone been running 5DT Data Glove 5 on Mac OS X. The Driver CD only contains versions for Linux and Win. After a quick search I found out that an Unix version is available but not for free ;( I would like to know if anyone has been testing this Unix driver for Mac OS X. Any experience on either Linux or Win is welcomed too Cheers Sylvain
