hello,

you shouldn't have to run configure script on debian/ubuntu just run make after installing the right package see README.txt

pkg-config determines the Pd and Gem's path if it doesn't work this is due to an old version or a bad installation and I don't know an easier way to fix it than editing Makefile

cheers

Hello pd-list,

I'm trying to compile pix_opencv on linux mint debian when : ./configure --with-pd=path_to_pd --with-gem=path_to_gem I get : checking for cvSobel in -lcv... no configure: error: you need to install opencv library (libcv)

of course, I've previously installed libcv2.3 libcv-dev libcvaux-dev libhighgui-dev with the package manager locate libcv gives : ... /usr/lib/libcv.so.4 /usr/lib/vlc/plugins/codec/**libcvdsub_plugin.so /usr/share/doc/libcv-dev /usr/share/doc/libcv2.3 /usr/share/doc/libcvaux-dev /usr/share/doc/libcvaux2.3 /usr/share/doc/libcv-dev/**README.Debian ...

did anyone already managed to compile pix_opencv on debian testing ? any magic ln -s command ? maybe pix_opencv relies on opencv v1 ?

thanks benjamin

thanks for this

I just tested your patch with a fresh install of Ubuntu and it doesn't work pix_opencv still depends both on opencv 1.5 and 2.3 it's a shame but I'll fix this later the svn version works on ubuntu after installing legacy packages : sudo apt-get install libopencv-dev libcv-dev libhighgui-dev libcvaux-dev

libopencv-dev is version 2.3.1 the others are legacy and install among others cv.h

concerning, pix_opencv_blobtrack, which version of opencv are you using ? check it with : echo $(pkg-config --modversion opencv)

cheers

FYI it does not build on archlinux (with opencv2).

I fixed some of it with the following patch: https://gist.github.com/**gusano/5814205https://gist.github.com/gusano/5814205

and now all externals build fine except for pix_opencv_blobtrack which gives the following error:

blobtrack.h: In function ‘CvFGDetector* cvCreateFGDetector1()’: blobtrack.h:20:113: warning: control reaches end of non-void function [-Wreturn-type] static CvFGDetector* cvCreateFGDetector1 () { return cvCreateFGDetectorBase(CV_BG_**MODEL_MOG, NULL); }

yep, I thought that this might be archlinux specific, that's why I didn't "officialy" submit my patch =)

afaik not this is related to opencv 2.4.5...

libopencv-dev is version 2.3.1

...

the others are legacy and install among others cv.h

2.4.5

i've just build it and yes it breaks compatibility...

I've push a fixed version to svn it should work with both version

could you please test it with 2.4.5 ?

thanks for pointing that

hum strange

i've made some change in the headers it should not depends on libcv-dev libhighgui-dev and libcvaux-dev anymore maybe this solve your problem too i've only tested with OpenCV 2.3.1 from packages

nice, it seems that all externals build fine now (except for pix_opencv_surf but it looks like it should not be build in the first place..). I still get this error at the end of the build though:

blobtrack.cpp: At global scope: blobtrack.cpp:643:1: error: ‘q’ does not name a type q ^ [snip]

                                      ^

hello,

it should be fixed now, i don't know from where the line 643 comes... but my gcc 4.6.3 doesn't complain for that

thanks for reporting

I still get the aforementioned error but after all externals have been built fine. but getting rid of dependencies is always nice =)

and here's another patch reflecting the new sf.net repo url in pix_opencv README:
