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

segfault on destroy or close
by Miha Tomšič 03 Dec '06

03 Dec '06

Hello! I have a small problem running Gem. I tried 0.90 and latest CVS on FC6. Whenever I destroy or close Gem window segfault is issued and pd dies. gdb using latest CVS reveals that they are two different problems. First there is a gdb bt for destroying a window sending destroy to gemwin. The second is bt for closing the Gem window from window manager I don't really know how to get more debugging info inside Gem.pd_linux and libGL.so.1 (using debuginfo with libGL.so.1 makes pd not to run insode gdb(?)). Any ideas, what to try next? Thanks and take care, M. --------------- (gdb) run Starting program: /usr/local/bin/pd -lib Gem [Thread debugging using libthread_db enabled] [New Thread -1208432960 (LWP 22866)] Program received signal SIGSEGV, Segmentation fault.

Mac Remote GUI
by Sebastian Heymann 22 Nov '06

22 Nov '06

Hello List, i am working on some additional gem externals for a little performance in some weeks. my target platform at the moment is an interl mac which is going to do all the rendering work. i want to control this machine from my laptop which is not powerful enough to do the rendering. so, the question is whether there is a way to do something like the x11 way ie. running gem on the fast machine and having the gui forwarded to the laptop using ssh. pd-gui somehow uses only a port and no ip address as a parameter. did someone deal with the same problem. help is highly appreciated. otherwise i would have to port everything to linux and get it running there. maybe i should post this to a general pd-list but perhaps i hope to find better results asking here. regards, sebastian

link errors on OSX-10.3
by IOhannes m zmoelnig 21 Nov '06

21 Nov '06

now that the AltiVec errors have been worked around, the build still fails on OS-X with a _very long_ traceback. see http://autobuild.puredata.info/auto-build/2006-11-19/logs/2006-11-19_03.15.… (this URL is one line) basically, the error looks like: ld: multiple definitions of symbol std::__throw_underflow_error(char const*) /usr/lib/gcc/darwin/3.3/libstdc++.a(functexcept.o) private external definition of std::__throw_underflow_error(char const*) in section (__TEXT,__text) /usr/lib/libstdc++.6.dylib(single module) definition of std::__throw_underflow_error(char const*) i see 3 possibilities: + "-bundle -undefined suppress -flat_namespace" is somehow the culprit + we need to link against another library to import the missing symbols + the exception handling is broken in Gem and/or in g++-3.3 (in conjunction with one of the used libs/frameworks) however, i have no real idea; it would be great if somebody could shed a light on it (and probably even a fix) mfg.adsr IOhannes

ArToolkitPlus -> Pure Data - Gem
by patrick 14 Nov '06

14 Nov '06

hi all, davide morelli did almost a working bridge of artoolkitplus and pure data - gem. i think it would bring many new possibilities to AR like opengl dataflow, sound, sensors, open sound control, video, physical modeling, importation of model (.obj) etc... please have a look at this url: http://www.davidemorelli.it/dokuwiki/doku.php?id=ar:augmented_reality_and_i… right now, the external is detecting the correct id of the marker and also follows each marker if we rotate it until the angle is below 90Â°... that would be fantastic if we can do this bridge. i cc artoolkit forum, many some people would be willing to help. pat

build errors on 10.3

The Mac OS X 10.3 build is still dying here. There hasn't been a 10.3 fix for many weeks. Could this be fixed? It could be done with an #ifdef for Mac OS X 10.3 alone, at the very least.
