Hi, So obviously, pix_opencv needs opencv 2.4 and you have version 3.1.
So there are 2 options : - grab opnecv 2.4 or built it yourself. - rebuilt pix_opencv against opencv3, but I doubt this will work out of the box, opencv API changes a lot between 2.4 and 3, but this is not a big work to adapt it though Cheers Antoine Le lun. 7 mai 2018 à 23:46, Jean-Yves Gratius <[email protected]> a écrit : > Hi Antoine, thanks for your answer. > 1) in verbose mode, i get the following lines when i try to create a > pix_opencv object in pd : > *tried /home/jyg/Documents/Pd/externals/pix_opencv/pix_opencv.l_ia64 and > succeeded* > */home/jyg/Documents/Pd/externals/pix_opencv/pix_opencv.l_ia64: > libopencv_video.so.2.4: cannot open shared object file: No such file or > directory* > > 2) Same result before and after doing the following command : > > *sudo apt-get install libopencv-* *3) When I search for opencv with > Synaptic, and if i check the properties for (for example) > libopencv-video3.1, it says that the installed files are > /usr/lib/x86_64-linux-gnu/libopencv_video.so.3.1 and > /usr/lib/x86_64-linux-gnu/libopencv_video.so.3.1.0 > > J.Y.G. > > On 07/05/2018 22:23, Antoine Villeret wrote: > > Hello, > > Why can't you load the lib ? > There should be some error in the console at least in verbose mode. > But iirc this build is dynamically linked to open CV. > So you need to install it with apt for instance > > + > A > > Le lun. 7 mai 2018 à 22:09, Jean-Yves Gratius <[email protected]> a écrit : > >> Hi list >> >> I have downloaded pix_opencv by Antoine Villeret from deken >> (pix_opencv-v0.4-(Linux-amd64-64)-externals.tar.gz) >> >> I cannot load the lib >> >> (pd 0.48.1, ubuntu 17.10) >> >> Any hint ? >> >> thanks >> >> >> >> _______________________________________________ >> [email protected] mailing list >> UNSUBSCRIBE and account-management -> >> https://lists.puredata.info/listinfo/pd-list >> > >
