OpenCV 2.4.5

[hellonico]

Trying to run the samples running OSX Mountain Lion and installed opencv through homebrew. I can get the library to compile no problem:

[niko@Modrzyks-MacBook-Pro-2][13:18][~/projects/vision/resources/lib/] % make            
[ 50%] Built target calibrate_cam
[100%] Built target vision

But none of the example is working. I got them running last year's summer, that seems ages ago :)

Anyway, any idea where to start looking ? Writing a short article right now, and one part was to introduce briefly vision.

Does it crash? Does it print any sort of info as to what went wrong?

[hellonico]

Sorry, I thought I did send the stack trace but I did not. Here it comes: Yes it crashes the REPL :|

display webcam spit out:

OpenCV Error: Unknown error code -10 (Raw image encoder error: Empty JPEG image (DNL not supported)) in throwOnEror, file /tmp/opencv-HweD/opencv-2.4.5/modules/highgui/src/grfmt_base.cpp, line 131 libc++abi.dylib: terminate called throwing an exception

[hellonico]

Got another one, but similar exception, when loading "window_listener.clj"

OpenCV Error: Bad argument (Unknown array type) in cvarrToMat, file /tmp/opencv-HweD/opencv-2.4.5/modules/core/src/matrix.cpp, line 698

[nakkaya]

Is it possible for you to test it with 2.3?

[hellonico]

I just tried with 2.3.1 to no avail:

user=> (load-file "src/segmentation.clj") OpenCV Error: Bad argument (Array should be CvMat or IplImage) in cvGetSize, file /tmp/homebrew-opencv-2.3.1a-3fAT/OpenCV-2.3.1/modules/core/src/array.cpp, line 1238 libc++abi.dylib: terminate called throwing an exception

Ha .. finally managed to get the C part of the stack trace:

Sorry for the late reply, I was out of town for a while. I no longer have access to a OS X box. I just compiled vision on two Linux boxes (Both ubuntu one with 2.3 one with 2.4). I can load the examples just fine.

@hellonico any progress you forget to mention? I'm currently have the same error on macos 10.9, opencv 2.4.9

[m9dfukc]

Hey, also interested in the current progress as im suffering the same issues.

[t3chnoboy]
