Can't install OpenCV 2.3.1 on OS X 10.8.3. I couldn't identify the problem. Will later OpenCV work with node-opencv?

[vgm106]

UPDATE: I went ahead and installed OpenCV 2.4.5 and tried to install node-opencv. I got the following

Interesting - node-opencv should work with later versions of opencv.

It looks from the error message that the build step is unable to find opencv - what happens when you run:

pkg-config --cflags opencv

in the console?

[vgm106]

This is what I have.
Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found

I followed this : http://stackoverflow.com/questions/15320267/package-opencv-was-not-found-in-the-pkg-config-search-path

I also included this in my .bashrc as well
#PATH for opencv.pc
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH

I placed opencv.pc in the path specified above

Hmm, this is a hard one to debug - building opencv really is a pain. I've had troubles with it as well - the opencv mailing list or irc may be a good place to ask.

I did a fresh install, and when I do
pkg-config opencv --libs, i get the following rather than -llibopencv_contrib -llibopencv .....

Problem Fixed for my issue.
I apparently did not install libopencv.
Installing it solved the trouble

[johnnaumann]

I get the following error:

/bin/sh: pkg-config: command not found
gyp: Call to 'pkg-config --cflags opencv' returned exit status 127. while trying to load binding.gyp

Any idea what I am doing wrong?

[haohcraft]

Have you tried brew tap homebrew/science brew install opencv

[collinalexbell]

Yes. Have tried brew install opencv Same errors occur upon npm install opencv

Hello,

I've had this problem too.
So searching on the web I found this guide. I did the opencv reinstall and now npm install opencv works fine!

The important details are:
make -j8
sudo make install

To build OpenCv in your /usr/local/ directory.

Hi Collin,

You can follow the link http://tilomitra.com/opencv-on-mac-osx/ provided
by Rafael or use this one
http://stackoverflow.com/questions/18122724/setting-installing-up-opencv-2-4-6-1-on-ubuntu-12-04-02
