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 exemple

Hope it will help and hope i have not made mistake.

Thx to Lluis for his help.

Any idea ?

I followed the instructions from :

Thanx.

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

  Referenced from:

/Users/lluisgomezbigorda/pix_opencv/pix_opencv_edge.pd_darwin

  Expected in: dynamic lookup

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!
