matcaffe installation error

[balakg]

I am getting linking errors when I run 'make matcaffe':

Undefined symbols for architecture x86_64:
"mxArrayToString", referenced from:
get_solver(int, mxArray_tag**, int, mxArray_tag const**) in caffe.o
...
"_mxCreateCellMatrix_700", referenced from:
str_vec_to_mx_strcell(std::__1::vector<std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator >, std::__1::allocator<std::__1::basic_string<char, std::__1::char_traits, std::_1::allocator > > > const&) in caffe.o

I saw other posts on this issue before, and I made the appropriate adjustment to this line in Makefile.config:

LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /Applications/MATLAB_R2016a.app/bin/maci64 /usr/lib

but I still get these compile warnings. I am using Matlab 2016a, and am on OS X 10.11. Any help would be appreciated.

Just in case this proves useful to someone else, the issue was resolved for me by changing the LIBRARY_DIRS order to:

LIBRARY_DIRS := /usr/local/lib $(MATLAB_DIR)/bin/maci64 $(PYTHON_LIB) /usr/lib 

Explanation
The problem was that I had defined

PYTHON_LIB := /usr/lib

previously in the Makefile, which consequently appeared before the maci64 directory in the path. Depending on your libpythonX.X.so location, the /usr/lib part of LIBRARY_DIRS may then become redundant.

Thanks for posting the solution!
