Fail Installation: OpenCV 2.4.6.1 on Mac OS X Mountain Lion

Question

I am frustrated with installing OpenCV 2.4.6.1 on My MacBook Pro Mountain Lion, I've tried so many ways using MacPort, CMake, Cuda to no avail.

I followed the instruction from this site http://sadeepj.blogspot.sg/2012/03/installing-and-configuring-opencv-to.html to install and configure OpenCV in MacOS X. However, when I run in the command line '$ make' it always results in error at [30%].

    [ 30%] Building CXX object modules/core/CMakeFiles/opencv_perf_core.dir/perf/perf_main.cpp.o

Does anybody know how to resolve this?

Thank you very much in advance :)

Answer 1

I have figured out how to solve this and posted it here: https://sites.google.com/site/yonasstephenfyp2013/updates/tutorialinstallingopencvonmacosxmountainlion

the essence of solving this is using the right version of OpenCV. At the time I installed, the stable version was OpenCV 2.4.3. Don't go for the latest version because it might be compatible yet with the new MacOS OS

Answer 2

you could just skip the performance tests for now. (you can always build them later, once this got solved)

add:

-D BUILD_PERF_TESTS=OFF

to your cmake cmdline

[edit]

looks you're having issues #3191 and 3179

both of them are fixed in 2.4 now https://github.com/Itseez/opencv/pull/1228 , https://github.com/Itseez/opencv/pull/1244

when did you download the code ? might consider getting a fresh copy ?
