Gem (cvs) load error on debian/etch
by B. Bogart 05 Jul '07

05 Jul '07

Hey all, I changed from nvidia's binary driver to the one in the etch repo (8776). Gem compiles (anon cvs update from today), but PD wont load it: /usr/lib/pd/extra/Gem.pd_linux: /usr/lib/pd/extra/Gem.pd_linux: undefined symbol: glUniform2i I've removed the files from the provided-by-nvidia-driver (--uninstall) Could there still be some headers somewhere and its compiling against the wrong opengl stuff? bbogart@insitu:~$ dpkg -l "*nvidia*" | grep ^ii ii nvidia-glx 1.0.8776-3 NVIDIA binary XFree86 4.x driver ii nvidia-kernel-2.6.18-3-686 1.0.8776-3+2.6.18-7 NVIDIA binary kernel module for Linux 2.6.18 ii nvidia-kernel-common 20051028+1 NVIDIA binary kernel module common files ii nvidia-kernel-source 1.0.8776-3 NVIDIA binary kernel module source ii nvidia-settings 1.0+20060516-3 Tool of configuring the NVIDIA graphics driv I'm lost, any suggestions? Attached is my config.log if that helps. Thanks, .b.

pix_video and dv1394 capture on Edgy
by Ivica Ico Bukvic 03 Feb '07

03 Feb '07

Hi all, Here I am 6 months later trying to upgrade my laptop and a new issue has cropped up with my video capture in Gem. System: Ubuntu 6.10 (edgy) i386 using udev Graphics: ATI 9600 running fglrx Kernel: 2.6.18-rt7 Video capture: el-cheapo camcorder run through ADVC-100 firewire device When running Kino, the camera gets captured just fine and everything "just works" as expected. However, in Gem (tried 0.90, CVS from November and another one from today's snapshot), I need to send following messages for Gem capture to work at all: device /dev/dv1394/0 mode NTSC driver 1 This starts capture reporting DV capture quality at 5, but the captured stuff is black. The only proof that things are getting captured comes from disconnecting the feed in the middle of the capture by pulling the video cable that connects camcorder with the ADVC-100 and then one can notice change in the color and/or momentary flicker of the captured area.

Error loading Gem undefined symbol
by Luigi Rensinghoff 23 Jan '07

23 Jan '07

I posted the same to the pd-list, but maybe this is a better place;-) Hi List i am trying to get a new system up and i am failing with loading Gem It compiles ok, but then i get : undefined symbol: glUniform2i i am on gentoo, maybe i have a wrong version of mesa or any other library. I was not able to find out. i suspected that it might have to do with gltt/freetype, since gltt does not exist anymore in portage freetype has changed to freetype2 I am really stuck here Thanks very much Luigi

Hallo, (I guess this was supposed to go to gem-dev as well).

I'm using data structures of course! Much better than Gem anyways because I can read out the current screen position of a rectangle much easier. Rotations are harder to do, though. (Just kidding, but only half.) > Did you switch to an older version of Gem maybe ? Yes, I'm currently running an older version of Gem. I always try to load a Gem.pd_linux after compiling without installing it, and if it doesn't load, I'll keep the old one. Ciao -- Frank Barknecht _ ______footils.org_ __goto10.org__

[Gem] Mouse click and open a file...
by Carlos Caires 16 Jan '07

16 Jan '07

Hi list, I have a white cube, inside the cube and side by side two rectangles, one blue, the other red. We can move the camera inside the cube. Here's my problem: I would like to be able to send a bang (for opening or playing a video-clip) when I "mouse-click" inside one of the two rectangles. For example, if I click inside the blue rectangle it will play the "first" movie (texturized in this rectangle), if a click on the red one it will play a "second" movie (in the red rectangle). In attached there is a preliminary patch. Anybody already had the same problem, question? Any help? I´m using: PD-0.38.4-extended-RC7 Mac OsX 10.3.9 Thank you. Carlos Caires

'official' support?
by chris clepper 16 Jan '07

16 Jan '07

Looking over the bug and error reports the past six months shows the majority of them coming from hardware and software configurations I do not and cannot not test (and probably would not want to run either). Would it make any difference to post a list of 'official' configurations which we develop and test? Linux with Nvidia binary drivers Windows with ATI and Nvidia hardware and binary drivers OSX with ATI and Nvidia hardware Maybe list a minimum GPU (Radeon 9000, Geforce 4, etc) and OS versions? While we won't do anything to block GEM from running on other configurations this statement would spell out what we have the resources to target. Anything not on the list we cannot reasonably test and people should know that those might not run as expected and problems may not get fixed. Or is this just officious?

glsl on ati radeon 9600 with linux
by cyrille henry 14 Jan '07

14 Jan '07

hello, i nead to use a computer with an ATI mobility radeon 9600. so i install ubuntu dapper, ati proprietary drivers, hcs pd extended 0.40.1 + compiled Gem from curent CVS. everythings works, exept glsl. the patch examples/02.advenced/16.vertex_program.pd and 17.fragment_program.pd work. but the patch 18.gl_shading_language does not work. the pd log print : linking: link 1.07374e+09 5.36871e+08 [glsl_program]: Info_log: [glsl_program]: Link successful. There are no attached shader objects. GL: invalid value glsl info is : [glsl_vertex]: Vertex_shader Hardware Info [glsl_vertex]: ============================ [glsl_vertex]: MAX_VERTEX_ATTRIBS: 32 [glsl_vertex]: MAX_VERTEX_UNIFORM_COMPONENTS_ARB: 4096 [glsl_vertex]: MAX_VARYING_FLOATS: 44 [glsl_vertex]: MAX_COMBINED_TEXTURE_IMAGE_UNITS: 16 [glsl_vertex]: MAX_VERTEX_TEXTURE_IMAGE_UNITS: 0 [glsl_vertex]: MAX_TEXTURE_IMAGE_UNITS: 16 [glsl_vertex]: MAX_TEXTURE_COORDS: 8 [glsl_fragment]: glsl_fragment Hardware Info [glsl_fragment]: ============================ [glsl_fragment]: MAX_FRAGMENT_UNIFORM_COMPONENTS: 4096 [glsl_fragment]: MAX_TEXTURE_COORDS: 8 [glsl_fragment]: MAX_TEXTURE_IMAGE_UNITS: 16 [glsl_program]: glsl_Program Hardware Info [glsl_program]: ============================ [glsl_program]: i think it's only a problem with the id that should not be converted to scientific notation, but i do'nt know what to do. anyone know how to link the vertex and fragment? thanks Cyrille

MMX fall back for SSE2 support?
by chris clepper 10 Jan '07

10 Jan '07

I had to redo my Win32 development machine and I am trying to get back up to speed. I can't figure out how to get a machine with SSE support to also do MMX for the pix_ objects which have no SSE code. This worked previously, but I cannot remember how it did.

Windows and MacIntel binaries
by chris clepper 09 Jan '07

09 Jan '07

I have a Windows and Intel Mac build of GEM that I believe are up to date and reasonably full featured. The only thing I could not get running on Windows is the fiducial tracking and the Pbuffer based code. I would like to post the binaries somewhere like IEM if possible. cgc
