GEM problem linuxppc
by Patrick Pagano 10 Mar '06

10 Mar '06

hi i have been tring to rid myself of a funky problem with Gem on linuppc[ubuntu] without any luck so i am putting this to the list again hopefully for some insights. when i start a gemwin, any one. the window is created as usual but there is no image/movie input i the gemwindowunitl the window is touched or re-sized. Is there a way to cure this? I am pretty sure the drivers are mesa, the card is a ati radeon 9600, glxgears and info both seem to work i have compiled gem-0.90.0 from source a few time and thought i had missed something. any suggestions?

Here i'm limited with my linux knowledge... I'm under Fedora Core4. Brand new installed and updated according to the administrator. I've checked the XF86Config and it seems I use only generic driver. The card is a NVidia GeForce 6600 GT. here is an extract of the XF86Config.eg that is in this path /usr/X11R6/lib/Server Do you think that installing a specific driver would work better ? I'm not sure that the info you need to help me.

Same problem after installing the last driver for my VGA card. Does anybody have a small mov file that I can test to see whether if it is my file or my system that fails. Do you have a check list to make sure the PD/PDP/PiDiP is well installed ? thanks you > > Sorry I made a mistake on my XF86config file since, FC4 use > X.org's system... > So here is my xorg.conf file with nvidia driver : > [...] > Section "Monitor" > Identifier "Monitor0" > VendorName "Monitor Vendor" > ModelName "Dell P1130" > DisplaySize 400 300 > HorizSync 30.0 - 130.0 > VertRefresh 48.0 - 170.0 > Option "dpms" > EndSection > > Section "Device" > Identifier "Videocard0" > Driver "nv" > VendorName "Videocard vendor" > BoardName "NVIDIA GeForce 6600 GT" > EndSection > > Section "Screen" > Identifier "Screen0" > Device "Videocard0" > Monitor "Monitor0" > DefaultDepth 24 > SubSection "Display" > Viewport 0 0 > Depth 16 > Modes "800x600" "640x480" > EndSubSection > SubSection "Display" > Viewport 0 0 > Depth 24 > Modes "1280x1024" "1152x864" "1152x768" > "1024x768" "800x600" "640x480" > EndSubSection > EndSection > > Section "DRI" > Group 0 > Mode 0666 > EndSection > > > Seems pretty ok to me.

compiling helloworld on winXP
by .: monsular :. 10 Mar '06

ok, thanks a lot cdr! i could now compile the project. but(!).. the outputted file was a helloworld.dll i now tried to import the .dll with "pd.ex -lib c:/path/to/external/helloworld" (tried wit and without file extesion .dll) but, what else .... this error followed in pd: -: can't load library load_object: Symbol "helloworld_setup" not found c:/path/to/external/helloworld: can't load library and now? the helloworld setup function is in the sourcefile. may this cause by a wrong compiled dll? or did i do something wrong at the importing? top error snipped, but be sure to send -DNT (or -DMSW) to the preprocessor > [Linker error] undefined reference to `post' > [Linker error] undefined reference to `pd_new' > [Linker error] undefined reference to `gensym' > [Linker error] undefined reference to `class_new' > [Linker error] undefined reference to `class_addbang' > ld returned 1 exit status > [Build Error] [obj.dll] Error 1 > > i don't know what i can do next... the linker needs some hints to find libpd, aka pd.dll (or pd.lib with MSVC). you could rename it libpd.dll, then -lpd would work (with GCC), or simply add the path to pd.dll to the linker arguments (absolute path, or relative if you did -Lbin/) > > what kind of project do i have to choose? dll? console? dll.. > should i do it better in visual c++? if you are using MSVC you additionally have to -DPD_EXTERNAL and weird tricks with declspec(dllimport) or something, so GCC is definitely simpler from a user standpoint..and if you are using GCC, add -mms-bitfields to the compiler flags so your external wont segfault when running in a MSVC-compiled host.. goodluck, looking forward to yer externals.. _______________________________________________ mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

Gem: color to pix
by Alexandre Quessy 10 Mar '06

10 Mar '06

Hi, Its been a little while since I am trying to _add_ a color to a pix. Is there a way to do so ? The thing is that if I put a colored rectangle over a pix_textured reactangle, it kind of desaturate the picture. I know such a thing is much easy in Gridflow, but I got to use Gem on OSX for this time again. If it is the only, though, I might try to compile Gridflow with its new export_pix and import_pix on OSX... aalex

Gerard van Dongen/Gilcher 1967-2006
by derek holzer 10 Mar '06

10 Mar '06

Gerard van Dongen/Gilcher passed away on Friday the 4th of March, after a brave battle with colon cancer. Gerard worked as a composer, musician and computer programmer in Rotterdam as well as played live with many improvisational and electronic musicians in the Netherlands including Bart Maris, Tom Wouters, Joe Williamson, Henk Bakker, Peter van Bergen and Ann LaBerge. He performed solo-concerts with electronics and/or piano compositions and played for numerous dance and theatre productions, produced radio-plays for the internet, and was a technical designer and software programmer for multimedia theater. Gerard was also an active member of the Pure Data and Linux Audio Developers communities, and contributed code for the user interface of the Ardour project. Gerard kept a very positive outlook throughout his illness, and he will certainly be missed. Marie Louise Gilcher has organized a memorial service for Thursday, 9 March at the "Crooswijk" Cemetery in Rotterdam. -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 118: "Make what's perfect more human"

Vancouver BC: Derek Holzer & Sara Kolster @ Video In Studios
by derek holzer 10 Mar '06

10 Mar '06

FOR IMMEDIATE RELEASE UPCOMING EVENTS + EXHIBITIONS Sara Kolster and Derek Holzer visibleSOUND/audibleIMAGE * resonanCITY: performance Friday, March 10th, 2006 @ 8pm * SoundTransit.nl: presentation Sunday, March 12th, 2006 @ 2pm *visibleSOUND/audibleIMAGE: screening and lecture Thursday, March 16th, 2006 @ 8pm * Pure Data: workshop Saturday, March 18th & Sunday, March 19th, 2006 @ 11-4pm both days Video In Studios / Satellite Video Exchange Society 1969 Main Street, Vancouver, BC, Canada 604-872-8337 ext. 3, event(a)videoinstudios.com http://www.videoinstudios.com Hours of Operation: Monday thru Saturday 11am-6pm The term visibleSOUND/audibleIMAGE implies the equal relationship or balanced use of image and sound. Within this theme, visiting artists Sara Kolster and Derek Holzer explore the connections between experimental audiovisual culture using the Internet and open source software. Kolster and Holzer find inspiration in the history of experimental cinema and electroacoustic music, as well as contemporary video and microsound practices. Together they explore contemporary ideas about “Live Cinema” through the use of Pure Data, an open source tool for manipulating sound and image. Gathered from various locations around the world, sound and image manifest into dream like journeys through Kolster and Holzer's live performance and net.art projects. Visually, Kolster's work deconstructs the analog/digital dichotomy while similarly, Holzer's digital sound treatments highlight and enhance the phonographic sources he collects. Kolster and Holzer reject the use of common, commercial production methods and the default, commercial artworks that these methods often produce, preferring instead to program their own software, build their own hardware interfaces and actively participate in the free and open source communities which surround these activities. Traveling from the Netherlands, Kolster and Holzer will be performing, presenting and teaching their practice at Video In Studios, 1965 Main Street, Vancouver, BC, throughout the month of March 2006. 1. resonanCITY: performance Friday, March 10th, 2006 @ 8pm Live audiovisual performance Both Holzer and Kolster find inspiration in the history of experimental cinema and electro acoustic music, as well as in contemporary "live cinema", improv and microsound practices. Many sounds and images in our everyday lives slip past our notice simply because they are too small, or because we lack the proper receivers to pick them up. resonanCITY is an ongoing project to gather these microscopic sights and sounds from various cities, and to amplify and transform them. Their performance work centers around the use of photographic transparencies, found objects, field recordings and sparse instrumentals to create layers of interrelated sound and image. 2. SoundTransit.nl: presentation Sunday, March 12th, 2006 @ 2pm SoundTransit.nl is an online, collaborative soundscape project by Sara Kolster, Marc Boon and Derek Holzer dedicated to field recording and phonography. On this site, you can book a sonic transit through a wide range of different locations recorded from around the world, or you can search the database for specific sounds by keyword, artist, country or location. A presentation of this project can include an introduction to field recording and phonography, a discussion on the importance of open licenses such as Creative Commons, or a technical discussion of the structure of the website. 3. visibleSOUND/audibleIMAGE: screening and lecture Thursday, March 16th, 2006 @ 8pm This lecture and screening, made up of "historic" and contemporary works from the collection of Montevideo/Nederlands Instituut voor Mediakunst (Amsterdam), investigates the interrelation of what has often considered to be two separate disciplines: sound and image. Works shown will include: 1) Steina & Woody Vasulka: Violin Power [US][1978] 2) Steina & Woody Vasulka: BAD [US][1979] 3) Servaas: 4 Poems [NL][1981] 4) Matthew Schlanger: Lizard Hearts [US][1986] 5) Nicolas Provost: Papillon d'Amour [BE][2003] 6) Jan van Nuenen: SET_4 [NL][2003] 7) Bas van Koolwijk: five [NL][2002] 8) Derek Holzer & Sara Kolster: resonanCITY [NL] [2005] 4. Pure Data: workshop Saturday, March 18th & Sunday, March 19th, 2006 @ 11-4pm both days A two-day Pure-Data workshop based on Sara and Derek's working style. $60 for members, $95 for non-members Email event(a)videoinstudios.com to register. Classes have a limited capacity. Workshop Details: http://www.videoinstudios.com/programming_details.php About the Artists Sara Kolster [NL 1978] is a visual artist with a background in design. Recently, the focus of her work shifted more towards video and film; capturing details from urban locations, visualizing fragments of stories of these environments. She uses different strategies, from time-based media (video, film, photography) to appropriated research methods belonging to different observational disciplines (journalism, documentary & archeology). Derek Holzer [USA 1972] is a sound artist with a background in radio and streaming media technologies. His work has focused on capturing and transforming small, unnoticed sounds from various natural and urban locations, networked collaboration strategies, experiments in improvisational sound and on the use of free software such as Linux and Pure-Data. Their work resonanCITY has been performed live in the US, Holland, Brazil, former Yugoslavia, the Baltic States and at the Transmediale 05 festival in Berlin. resonanCITY also took the Second Prize at the 11th International WRO Media Art Biennale in Wroclaw, Poland in May 2005.

Hi Tina, Usually an installation of Python will add its directory to the environment variable %PYTHONPATH%. Open a command window: <WinKey>+R cmd /k <enter> >set | find "PATH" you should see a listing for PYTHONPATH there. Make sure this points to your actual installed location for Python (usually c:\python24). If not, try: >set pythonpath=%PYTHONPATH%;c:\actual_python_location\ Then reboot. Windows can't do anything without a reboot. py.dll is the dll for the Thomas Grill's external and you need to have its full exact path specified in Pd's Path... options. It fails to load if it can't find Python24.dll, but pointing Pd directly to Python24 doesn't help... Hope that helps you! David this lists your environment variables.

Hallo! > thanks, I'll try that - I'm new to cvs and compiling, just jumping in > at the deep end by setting up this box from scratch after using pd on > OSX for a couple of years okay: - how to download gem from cvs: http://gem.iem.at/download.html#CVS (you don't need GemLibs) - then you have to install all dependencies - see [1] - then go into Gem/src and try configure - make (or see README.linux in Gem/src) LG Georg [1]: Debian-users: ============= On a Debian system (most of) these library are already in your distribution. Some packages, that are not in the official Debian-release (esp. libmpeg3(-dev)), can be found at http://marillat.free.fr you might have to put a line like deb http://marillat.free.fr/ stable main into your /etc/apt/sources.list #> apt-get install libgl-dev ftgl-dev libtiff3g-dev libjpeg62-dev libmpeg3-dev libavifile-0.7-dev libquicktime-dev libdv4-dev
