Antoine,
You can embed the libraries using the ./embed-MacOSX-dependencies.sh script, just run it like this:
cd pix_opencv ./embed-MacOSX-dependencies.sh .
Then it'll copy all of the libs from Fink into the pix_opencv folder, then that folder can be tarred up and its the library. I also automated this using our jenkins server, so whenever a new commit is pushed, it should automatically build the full library for Mac OS X powerpc, i386, and x86_64. Here are the most recent builds:
http://autobuild.puredata.info/auto-build/2013-02-07/
And here is the jenkins job: https://macosx105-i386.pdlab.puredata.info/job/pix_opencv

hi,
thanks for the feedback,
I thought it was dynamically linked I tested it on a Mac OS 10.6.6 32bit machine where I installed OpenCV 2.3.3 with Fink and it works well
should I embbed the library in the mach-o ? if so, I don't how to...
but actually I made few changes after the build I've tested and before uploading so maybe I broke something...
I will give it a try tomorow
cheers

hey antoine
i just tried your build and it didnt work. i get:
/Users/megrimm/Desktop/pix_opencv/pix_opencv_athreshold.pd_darwin: dlopen(/Users/megrimm/Desktop/pix_opencv/pix_opencv_athreshold.pd_darwin, 10): Library not loaded: /sw/lib/libopencv_core.2.3.dylib Referenced from: /Users/megrimm/Desktop/pix_opencv/pix_opencv_athreshold.pd_darwin Reason: no suitable image found. Did find: /sw/lib/libopencv_core.2.3.dylib: mach-o, but wrong architecture /usr/local/lib/libopencv_core.2.3.dylib: mach-o, but wrong architecture
because your dylibs are not embeded in the folder (mach-o, but wrong architecture errors are from my 64bit builds)
./embed-MacOSX-dependencies.sh finds all the dynamic libraries needed and embeds them in the folder. Then you can tarbz the whole
pix_opencv
folder, and that's the installable library. Just drop that into ~/Library/Pd or /Library/Pd.
so this didnt seem to work?

hi,
so i made a folder called "antoine" in the home of pddev on

i build pix_opencv against latest Gem and pd vanilla 0.44 it doesn't compile with pd-extended (sorry for that)
i've made a tarball of the folder and put it here : http://puredata.info/Members/avilleret/pix_opencv_macosx_20130131/view how can i put it on the pix_opencv page ?

Hi Hans and all,
happy new year and thanks for your work
sorry for the delayed answer, I was far away from Internet in the mountain for few days...
Definitely don't apologize for that, I wish I had been in the mountains
:)
I can log through SSH on pdlab computers (not tested all for now) but
I
have few more questions :
1- What can I do and (more important) what should I never do on those machines (particularly about SVN checkout and installing / updating
lib)
The pddev is pretty locked down, so I think you'd have to try to mess things up bad. The biggest worry would be filling up the disks on some of the VMs, since they are only 9 gigs. I think the Macs all have lots of disk.
2- There is no "pix_opencv" folder in the pddev home (on macosx105-i386.pdlab.puredata.info) where could I find the up-to-date folder ? should I cd to /Users/pddev/pure-data/trunk/externals/pix_opencv (this seems to be
very
old) ? Where should I work ?
Work wherever you'd like. I generally put svn checkouts in ~/code, use that, or ~/pure-data, or create your own folder if you want. I think the biggest rule would be don't mess with or delete files there that you didn't create.
sorry for those silly questions, but i don't want to break
something...
Thanks for asking!

Yup, its verified. :)

Hey Antoine,
So I installed OpenCV 2.3.1 on the PdLab Macs using Fink, and fixed
the
Makefile to use pkg-config on all platforms. I don't know the
protocol on
editing the README, so I didn't touch it. It would make things
easier for
users if there was only one build system and the README only covered
that.
I'll leave that to you. Here's how to make a build on Mac OS X:
$ . /sw/bin/init.sh (load Fink for other libs like opencv) $ cd pix_opencv $ make
PD_PATH=/Users/pd/auto-build/pd-extended/packages/darwin_app/build/Pd-0.43.4-extended-20121231.app/Contents/Resources/
$ ./embed-MacOSX-dependencies.sh .
./embed-MacOSX-dependencies.sh finds all the dynamic libraries needed and embeds them in the folder. Then you can tarbz the whole
pix_opencv
folder, and that's the installable library. Just drop that into ~/Library/Pd or /Library/Pd.
For the PdLab Macs, building on macosx105-i386.pdlab.puredata.infowill include the 32-bit libraries, which is what you need for current
versions of
Pd-extended for Mac OS X. Gem included in Pd-extended doesn't work
for
64-bit (Gem master does at this point, I think). Building on macosx106-x86_64 (chaos.medien.uni-weimar.de) will make 64-bit
builds.
For someone to build this on their own machine, they'll need to do:
fink install opencv-dev
On a related note, if you stick with the Library Template Makefile
and
layout, that it'll be trivially easy to make Debian packages for it.
I can
do that too, or leave it to you.
