gem_route?
by james tittle 12 Oct '05

12 Oct '05

hiya, ...after peeking into pdp some more recently, I found a really useful object: pdp_route...basically it just creates a number of outlets and routes the input to an outlet based on a number sent to it's left inlet...very simple object, and it seems we could/should have such a beast for gem states, too, because I'm tired of doing the whole route/ spigot/lots of other objects for the same effect... ...so, I'd be up to trying this, if other's think it'd be useful and not "bloatful" ;-) james

pd/gem locks up linux and keyboard in CCRMA FC3
by Spec 08 Oct '05

08 Oct '05

I compiled pd v0.39 and then gem v0.9 it seems some functions cause a complete lockup particularly loading the 08.model.pd example in the 01. basic directory. I ran an strace on it then stripped the trace file of chaff using sed, the last major commands in the log before I lost keyboard/gnome/x were ioctl(15, FIONREAD, [0]) = 0 ioctl(15, FIONREAD, [0]) = 0 ioctl(15, FIONREAD, [0]) = 0 recv(4, ".x8149350 menuclose 1;\n", 3650, 0) = 23 ioctl(10, 0xc0384641, 0xbfffd934) = 0 munmap(0xb54d8000, 266240) = 0 munmap(0xb592b000, 266240) = 0 munmap(0xb5523000, 8192) = 0 munmap(0xb5525000, 8192) = 0 munmap(0xb5527000, 8192) = 0 munmap(0xb5521000, 8192) = 0 munmap(0xb551f000, 8192) = 0 munmap(0xb551b000, 8192) = 0 munmap(0xb5519000, 8192) = 0 munmap(0xb551d000, 8192) = 0 munmap(0xb596c000, 622592) = 0 munmap(0xb58ea000, 266240) = 0 shutdown(15, 2 /* send and receive */) = 0 close(15) = 0 shmat(4294967295, 0, 0) = -1 EINVAL (Invalid argument) shmdt(0xb57a9000) = 0 ioctl(10, 0xc00c4642, 0xbfffd95c) = 0 brk(0x824b000) = 0x824b000 send(4, ".x8149350.c delete l814b060\n.x81"..., 3456, 0) = 3456 +++ killed by SIGKILL +++ But the program had only locked the keyboard and Xwindows (mouse still moved but nothing responded, and still a load of gettimeofday etc. messages in tracefile (stripped by sed) before the sigkill which was the power button (only way to restart/break) and everything still seemed to be running away in background. I'm wondering if its a gcc compiler/library version problem, would it be possible to let me know versions of all the libraries and which gcc you last tested it on linux was? It works OK on my laptop in windows using windows binaries and has not crashed on me once, but the directx opengl seems slower than opengl on my xorg fc3 CCRMA linux box (on the patches where gem works...:)) I'm using nvidia display drivers?, Maybe its the gem patches? I'm stumped, any help appreciated. Its a shame because pd/bonk~/gem with RT audio in looks a superb concept.

text2d issue
by Tim Blechmann 07 Oct '05

07 Oct '05

hi all, i wrote a gem patch on linux, that behaves differently on windoze: it's basically this setup: |gemhead| | |color| | |text2d| it seems, that i can't change the settings of the |color| object. especially setting the alpha value doesn't work on windows. since it's working fine on my linux machine (gem/cvs, nvidia binary driver) i think it's an issue of either the windows driver on the other machine (iirc an ati dualhead card) or an issue of the gem-0.90.1 binary (haven't been able to test the current cvs ... no development environment on that machine). any ideas? thanks ... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 http://www.mokabar.tk latest mp3: kMW.mp3 http://mattin.org/mp3.html latest cd: Goh Lee Kwang & Tim Blechmann: Drone http://www.geocities.com/gohleekwangtimblechmannduo/ After one look at this planet any visitor from outer space would say "I want to see the manager."

Gem rendering
by Christian Veit 06 Oct '05

06 Oct '05

Hello list, I have a problem with rendering in Gem. If i start rendering a simple patch with [pix_film] or [pix_video] pd is using nearly 100% of cpu time and the texture on a [square] is too big and the frames are stumbling. When stopping rendering and starting it again cpu usage is at 70% and performance is ok. If i load a new film there is the same behaivior like starting the first time. In Gem 0.90 there is also very slow response to the mouse and keyboard events. I've checked out a version from CVS there are no problems with the mouse and keyboard events but video playback the first time while rendering is the same stumbling thing. I'm on Linux with an ati radeon mobility x700 graphic card... lg Christian -- 10 GB Mailbox, 100 FreeSMS/Monat http://www.gmx.net/de/go/topmail +++ GMX - die erste Adresse für Mail, Message, More +++

URGENT: clock_delay Hangup??
by B. Bogart 06 Oct '05

06 Oct '05

Hey all, What the heck is going on here, I've been getting a bunch of crashes in Gem on this machine wen it seemed to work fine on my home macihine. Anyhow its a AMD semperon sarge 2.6.8 w/ nvidia drivers. This is the latest crash, Program received signal SIGHUP, Hangup. [Switching to Thread 1076181440 (LWP 3239)] 0x080a3236 in clock_delay () (gdb) bt #0 0x080a3236 in clock_delay () #1 0x080e10aa in x_misc_setup () #2 0x084bc240 in ?? () #3 0x00000000 in ?? () #4 0x40408000 in _classGEMglIndexi () from /usr/lib/pd/extra/Gem.pd_linux Previous frame inner to this frame (corrupt stack?) Any ideas? I'm going to try and drop to Gem0.90 and see if that is any better. It took a huge amount of effort to make Gem texture properly and do video4linux, so I'm worried Gem090 is not working to work, anyhow I'm trying it now. If anyone has an Idea about this let me know. Could it be the nvidia driver somehow? I also got crashes from libGL and pix_flip before. Thanks b.

URGENT! Gem CVS messing up textures on ATI machine
by B. Bogart 03 Oct '05

03 Oct '05

Hey all, I'm in the thick of installing my art project and am trying to get my patch to work on the linux machine provided from artengine. It is a sarge semperon machine with an accelerated ATI 9600. Problem is I can't get pix_image, pix_multiimage or even pix_video to texture properly. The image seems to be both cropped and stretched to the point of abstraction. the Gem help patches do not work... Attached is a visual illustration, loaded the TEMP2.jpg file here. So I really need this to work, what is going on what do I need to do? I will have to resort to buying a nvidia card, since I suspect it is the graphics card causing this problem. Please reply ASAP as I'm running fast out of time to get this to work. b.

GLTT anyone ?
by IOhannes m zmoelnig 03 Oct '05

03 Oct '05

i jsut got an email from an "upset customer" who tried to compile Gem on fedora and failed due to code in the GLTT-section of TextBase. now this makes me wonder, whether we really still need the GLTT parts lying aroung, or whether we could completely throw them out of the code-base. nowadays, FTGL is used on linux, osX and w32; i have no idea about irix (and other possible platforms) however, if there are still major distributions around that don't have FTGL-support it might be better to not throw it out. any comments, thoughts, ideas ?? mfg.asd.r IOhannes
