I did successfully compile pix_opencv with the opencv package available for the rpi 3 (which is opencv 2, the one needed by pix_opencv) with latest pd and Gem from github.

It worked well except while trying to compile / use the additional
facetracking lib which produce a segfault

with the facetracker lib you might need to look for the opencv2 branch.

also, [pix_opencv_facetracker] needs the "model" directory to be in the same directory as the root patch otherwise it can't find the face model file and that causes a segfault.

i tried compiling on debian as well but i got the opencv 3 lib instead and messed up the dependencies. i will try later this week and report back, but this is rather hard because i would need to compile opencv2 and that i tried and it was a pain.

is there an opencv2 package for debian?

Is anyone else able to compile/load pix_opencv with Gem 0.93.3 on 64bit
Debian testing?
well, yesterday, I compiled pix_opencv following the instructions here
https://github.com/avilleret/pix_opencv/wiki on a fresh debian 9 64 bits
(so not testing ...)
Thank you Benjamin, this is good to know!

with Pd and Gem (0.93.3) coming from the debian repository
So that might then be package versions Pd 0.47.1-3 and Gem 1:0.93.3-10+b3

Could you let me know which opencv libraries you have installed on that
machine, for example by posting the output of the command
aptitude search opencv | grep ^i
?

Thank you again!
P
