Argghh, I didn't try the objects and they freeze (or sometime crash)
my PD.
The objects draw perfectly under PD but i got this error :
error: [pix_opencv_contours_convexity]: cannot handle this format
(1234567) !
or
[pix_opencv_haarcascade]: ERROR: Could not load classifier cascade
Why ?
Any idea ?

OK, now it works on PowerPC, MacOSX.4.11
Here the method :
• Download this three libraries with Fink : libjpeg + libpng3 +
libtiff• In Terminal : cvs -d:pserver:anonymous@opencvlibrary.cvs.sourceforge.net:/cvsroot/ opencvlibrary login ----> then hit 'enter' on your keyboard cvs -z3 -d:pserver:anonymous@opencvlibrary.cvs.sourceforge.net:/ cvsroot/opencvlibrary co -P opencv ----> download opencv sources
• with a text editor, open the file : cvcap_qt.cpp look for '__BEGIN__' and change it by '__BEGIN__{' look for '__END__' and change it by '}__END__' ----> save
• In Terminal ----> go to your opencv folder you just download and create a new
folder 'build' : cd blabla/opencv mkdir build cd build ../configure CPPFLAGS="-I/sw/include" LDFLAGS="-L/sw/lib" make sudo make install ----> enter your password• With you browser go to : http://hangar.org/wikis/lab/doku.php?id=start:puredata_opencv ----> download pix_opencv-0.1a.tar.gz and decompress all : http://hangar.org/wikis/lab/pd/pix_opencv-0.1a.tar.gz ----> download PD-extended sources and decompress all : http://downloads.sourceforge.net/pure-data/Pd-0.39.3-extended.tar.bz2 ----> download the makefile for macosx : http://hangar.org/wikis/lab/pd/opencv/Makefile.darwin
• In the Finder : ----> change 'Makefile.darwin' by 'Makefile' and then overwrite
the 'Makefile' in 'pix_opencv' folder you just download• With a text editor : ----> open this new 'Makefile' and change : PD_DIR = /*/Pd-0.39.3-extended/pd (enter the path of the 'pd'
folder in 'Pd-0.39.3-extended' folder you just download from
sourceforge) GEM_DIR = /*/Pd-0.39.3-extended/Gem (enter the path of the 'Gem'
folder in 'Pd-0.39.3-extended' folder you just download from
sourceforge) ----> save• In Terminal : ----> go to the folder 'pix_opencv' with 'cd ' export MACOSX_DEPLOYMENT_TARGET=10.4 make clean make
• Then copy the '.pd_darwin' create in the 'pix_opencv' folder in
your '/Applications/Pd-0.40.3-extended-20080315.app/Contents/ Resources/extra/Gem/' for exempleHope it will help and hope i have not made mistake. Thx to Lluis for his help. ++

However, when I try to load any of them PD gives me this error::

I got this error too, but only when gem was not loaded. when gem is loaded, everything is fine.
In order to make the opencv objects work I always had to set colorspace RGB. otherwise, I did no see any effect. I think the default on
osx is yuv. anyway, will test a little more. great stuff! marius.
