Does Gem makefile on OSX look for FTGL static libs? compiling Gem CVS on OSX from terminal
by B. Bogart 30 May '06

30 May '06

Hey all, Here is this thread again. So once I was all happy with my new CVS binary of Gem, I realized (to my dismay) that of course I compiled without font support. So remembering the ol Xcode days I found FTGL and freetype and compiled like so: Freetype: (easy) ./configure make sudo make install FTGL: (scarry) used the "unix" folder since it was the only one with a makefile. did sudo ln -s /System/Library/Frameworks/OpenGL.framework/Versions/A/Headers /usr/include/GL so that the makefile found the GL stuff. ./configure --without-x --with-ft-prefix=/usr/local/lib --with-ft-exec-prefix=/usr/local/lib/ --disable-freetypetest --disable-shared --with-gl-lib=/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/ make sudo make install seemed to work, though I did not try compiling the test. I see FTGL includes and binaries. Note this does create static libs. So GEM can't see the FTGL stuff: ./configure --with-ftgl --with-ftgl-includes=/usr/local/include/ --with-ftgl-libs=/usr/local/lib/ checking for ftgl-config... yes checking for main in -lftgl... no checking for PKG_GLTT_CFLAGS... checking for PKG_GLTT_LIBS... used optional libraries: font-rendering : image-support use ImageMagick : no use TIFF : no use JPEG : no video-support use mpeg : no use mpeg-3 : no use QuickTime : yes (framework) use aviplay : no use ffmpeg : no input-support use v4l : no use ieee1394 : no misc using ARB-extensions : yes using NV-extensions : no using reg-struct-ret : yes So I got most of the FTGL stuff from the blender compile howtos, but I'm stuck with forcing gem to see FTGL... Maybe gem is only looking for dynamic libs not static ones? I'd rather FTGL be linked in static since that way I don't have to make sure FTGL is compiled and working on each machine in the lab... Thanks all! .b.

Gem pix_video on Fedora Core 5
by thewade 29 May '06

29 May '06

I installed Fedora Core 5 and now I can build and load gem without disabeling anything! Sweet! Except that pix_video still doesn't work with udev: /dev/dv1394/0 I have tried changing to [driver 1< when rendering was enabled and this crashed PD. I tried [driver 1< before rendering and PD didn't crash but I didn't get video. With [device /dev/dv1394/0< I got the following message: device-err: 0 DV4L: closed Is there a way to get Gem pix-video to work in fedora core 5 with udev or is the only way to get pix_video to work is to use devfs? Thanks all! -thewade

I thought that this works ... (but never tried it) ... anyway, you can change the following in videoDV4L.cpp (I think line 194): if ((fd=open("/dev/dv1394", O_RDWR)) < 0) { to: if ((fd=open("/dev/dv1394/0", O_RDWR)) < 0) { and then recompile ... @GEM-devs: maybe we should introduce a message to set the device properly ? (and document it in the help file ;) ...) LG Georg -- Bis zu 70% Ihrer Onlinekosten sparen: GMX SmartSurfer! Kostenlos downloaden: http://www.gmx.net/de/go/smartsurfer

video of a jungling performance using gem
by cyrille henry 23 May '06

23 May '06

hello, After somes technical problems that we send to this list, Adrien finnaly completed his jongling performance using real time video. i worked the gem patch. finally, the 100fps camera was not working on real time and we used pd (hsc ppc version) on roseta, with a macbookpro. from a technical point of view, the projection is made on a half transparent screen, in front of the sceen. the jongler is behind this screen. you can have a look at the result of this work : http://a.mondot.free.fr/vid/reTimeWeb.mp4 this video is not intended to be difused. others informations should be found on adrien website when he will have time... http://www.adrienm.net/ thanks for your help.

Re: [PD-dev] oprofile - streamlining Pd/gem patch
by B. Bogart 18 May '06

18 May '06

Hey gem devs, How can I compiled gem without striping it? I'm having trouble trying to use oprofile to profile the gem functions, it seems to just see the internal pd functions. I tried removing the "strip" from the Makefile after doing autoconf/configure but that does not seem to be doing anything. So I'm starting profile with: opcontrol -i /path/to/pd --start Stoping with: opcontrol --shutdown Looking at the results with: opreport -d How can I compile a Gem binary (on linux) so that I can profile with oprofile? Thanks all. I'll think I'll be giving up soon, will be back at it again tommorrow, I really need to figure out what is causing these CPU jumps... .b.

I don't know whether Günter means switching away from SourceForge, but I really think that the whole Pd CVS should leave SourceForge right now. The web services like patch-tracker and bug-tracker and downloads and such can all stay on SourceForge, I don't mind, but the CVS has to leave because there are too many problems. Actually, because Chun and I really have to work on DD alot these days and the CVS is just plain down, we'd rather move out tomorrow than waiting June 1st, but if SF is up tomorrow until the 30th I don't mind. If SF has longer downtime I'll make an emergency fork. _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801 - http://artengine.ca/matju | Freelance Digital Arts Engineer, Montréal QC Canada

CVS Gem.linux load error: undefined symbol: glUniform4iARB Gem: can't load library
by thewade 13 May '06

13 May '06

Hello, I know CVS is bleeding edge so this is just a little feedback. My machine is an AMD64 FC4 machine running in 32-bit mode. I am using pd-0.39-1 and Gem from CVS just moments ago (2006-05-07). I had a working version of Gem installed except that I couldn't get my camcorder to work with pix_video because it was looking at /dev/dv1394 for my device, where as it should be looking at /dev/dv1394/%d, or so I think. So I download and build the CVS Gem (I also had to ln -s /usr/local/include/FTGL /usr/include/FTGL and remove the -msse2 flag to get the thing to compile). When I ran PD I got: usr/local/lib/pd/extra/Gem.pd_linux: /usr/local/lib/pd/extra/Gem.pd_linux: undefined symbol: glUniform4iARB Gem: can't load library What can I do to make this work? Lastly, but not least, thank you (all) for writing such great software and just giving it away. When I become famous (HA! Or at least get out of debt!) I want to donate a bunch of money to all the opensource packages I use! -thewade

new win32 build
by chris clepper 12 May '06

12 May '06

I put a build up that fixes the crash when QT load, has some of my more recent pix_ objects and does ARB_ shaders. I also moved the QT init code into the GemMan init and added a fps output to gemwin (not checked into CVs yet). The biggest problem I have is that pix_film runs at like 2 seconds per frame when the first clip is loaded, but starting and stopping rendering fixes it. pix_video does the same. Also, texturing performance is really bad on the FireGL here. Anyone still attempting GEM on Windows want to test it? http://taproot.dyndns.org/~cgc/downloads/Gem.dll cgc

The principal problem seems to be the host, not CVS. So finding a better host could solve that problem. The svn transition is just an addon, which could be done at the same time but doesn't address the same problem.
