Installation Issues: Undefined symbols for architecture x86_64

[Charles Prado]

Hello everyone, I'm trying to compile CAFFE but I'm having some issues. This time the problem is related to OpenCV, and says: 

Undefined symbols for architecture x86_64:

  "cv::imread(cv::String const&, int)", referenced from:

      caffe::WindowDataLayer<float>::load_batch(caffe::Batch<float>*) in window_data_layer.o

      caffe::WindowDataLayer<double>::load_batch(caffe::Batch<double>*) in window_data_layer.o

I'm running OSX 10.4 and my OpenCV was installed via brew (I also have another installation of OpenCV but it's isolated). OpenCV is installed on path: /usr/local/Cellar/opencv. I already tried to edit these lines:

# Whatever else you find you need goes here.

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/local/Cellar/opencv/2.4.11_1/include

LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/local/Cellar/opencv/2.4.11_1/lib

and these:

# If Homebrew is installed at a non standard location (for example your home directory) and you use it for general dependencies

INCLUDE_DIRS += $(shell brew --prefix)/include

LIBRARY_DIRS += $(shell brew --prefix)/lib

...with no effect...

Any suggestions?

Ok guys... "problem" solved... the solution is very simple... If someone have the same issue, the solution is 

# Uncomment if you're using OpenCV 3

OPENCV_VERSION := 3

uncomment this line on makefile... u.u

yes... I didn't noticed that line until now. As said here, this error is generated "[...] probably because imread was moved to opencv_imgcodecs [...]".

omg it worked.

you literally saved my day.

thank you!!
