Compile error in Ubuntu 14.04 with Matlab 2011b

Hi, I get the following error in 'make' command:

I'm using the current version of the openCV (2.4.9) and mexopenCV

[amroamroamro]

Make sure you are compiling against the stable OpenCV 2.4.9, not a dev version. If you already are, then you probably have an incorrectly configured setup (start by checking the output of pkg-config --cflags --libs opencv).

---

If you follow the included header files, you get:

$MEXOPENCV/src/+cv/adaptiveThreshold.cpp
-> $MEXOPENCV/include/mexopencv.hpp
  -> $MEXOPENCV/include/MxArray.hpp
    -> $OPENCV/opencv2/opencv.hpp
      -> $OPENCV/opencv2/imgproc/imgproc_c.h
        -> $OPENCV/opencv2/imgproc/types_c.h

which is where those constants are defined in v2.4.9

Once the next version of OpenCV is released, those constants will probably need to be renamed as:

const ConstMap<std::string,int> DistType = ConstMap<std::string,int>
    ("User",   cv::DIST_USER)
    ("L1",     cv::DIST_L1)
    ("L2",     cv::DIST_L2)
    ("C",      cv::DIST_C)
    ("L12",    cv::DIST_L12)
    ("Fair",   cv::DIST_FAIR)
    ("Welsch", cv::DIST_WELSCH)
    ("Huber",  cv::DIST_HUBER);

Until then, the only ones defined in v2.4.9 are CV_DIST_*. Same goes for CV_AA and probably other constants.

Thank you, solved

I am running into the same problem using opencv2.4.9 (with the 2.4 mexopencv branch here)

Any help welcome....

[amroamroamro]

@jeremy-rutman: are you sure you checked-out the v2.4 branch not master?

According to the the line number in the error message (mexopencv.hpp:84), I would say you working out of master branch (which targets OpenCV 3.0, not 2.x)...

In v2.4 branch, that enum value doesnt appear on the line mentioned: https://github.com/kyamagu/mexopencv/blob/v2.4/include/mexopencv.hpp, please double check which branch you are on.

[jeremy-rutman]

Thanks for the help. I tried git checkout v2.4 and git pull then make, and get yet another error .... as its a multiple definition error maybe I added extra unnecessary lib directories to opencv.pc?

@jeremy-rutman: I suggest you revert all changes you've made, and try again. The closed issues you've read about tinkering with opencv.pc or Makefile have since been fixed in 2.4, and you shouldn't have to edit anything manually...

# OpenCV 2.x
$ sudo apt-get install --reinstall libopencv-dev

# mexopencv
$ cd mexopencv
$ git reset --hard
$ git pull
$ git checkout v2.4
$ make clean && make

[jeremy-rutman]

Ok thanks , a good compile occurred it seems (I tried 'make clean' then 'make' which worked in the meantime but I imagine your suggestion would have done it too). Now I am up against an error in 'paper-doll' which is the reason why I downloaded mexopencv in the first place - I guess it may be offtopic but it is related I blv: when I run 'make' from matlab to make the clothes parsing tool (http://vision.is.tohoku.ac.jp/~kyamagu/research/paperdoll/) , I get yet another series of errors starting with

[amroamroamro]

@jeremy-rutman Well @kyamagu is more qualified to answer questions regarding his paperdoll project, but I believe the issue you're seeing is related to #91, meaning you're gonna have to downgrade OpenCV if you wanna keep using an older version of mexopencv... (try OpenCV 2.4.6 or 2.4.7)

[kyamagu]

@jeremy-rutman Well, I cannot give a thorough support for a proof-of-concept work like paperdoll, but the easiest fix is just to replace the mexopencv directory inside the paperdoll package with the fresh v2.4 branch of mexopencv.

[amroamroamro]

I guess this is the same thing with any scientific or academic project. If you want to test a certain published code, you're gonna have to recreate the exact versions of frameworks and tools that were used when developing the project. As software is always updated, there's bound to be breaking changes...
