Caffe installation failing on OS X 10.11 - Undefined symbols for architecture x86_64:

[bpraveenk]

Hi

I see "Undefined symbols for architecture x86_64:" error when i try to build Caffe on Mac which has OS X version 10.11.6 running on it.
I did follow the instructions mentioned here : http://caffe.berkeleyvision.org/install_osx.html, however i still see the error. I even downgraded the version of Xcode from 7.3 to 7.0 as was suggested in one of the blogposts i encountered.

I have the following dependencies installed and I have Cuda version 7.5 installed.
snappy-1.1.3
leveldb-1.18
gflags-2.1.2
glog-0.3.4
szip-2.1
lmdb-0.9.14
homebrew/science/opencv-2.4.13
protobuf-2.6.1

I have attached the Makefile and Makefile.config with this email.

Hi,
I am getting the same error. Where you able to solve it?

[simonb83]

I got this error while trying to compile release candidate 3. I ended up cloning the latest master branch (as of Aug 11th) and was able to compile that successfully.

Please ask installation questions on the mailing list. If you're having trouble, you might want to try the Caffe Dockerfile to take care of installation for you.
