Undefined symbol with anaconda running python 3.6 #443

Closed scottandrews closed 7 years ago

scottandrews commented 7 years ago

I believe there is an incompatibility for the build dlib install script and the latest anaconda. When I install on Mac after a fresh install of anaconda running python 3.6, I get the following error. Most of the log are deprecation warnings, but I can't find the fix for the final undefined symbol error. The install below is from "pip install dlib" but the same error occurs if I download directly from github and run "python setup.py install"

It looks like it may have something to do with linking to boost, which I installed using "conda install boost." Version 1.61.0 installed cleanly.

Your boost python install is messed up. Based on the amount of posts I get about this, it would seem like the package managers on the Mac generally mess up boost.python binaries. I don't know what their deal is, but a huge number of people have trouble using boost.python on the mac when boost.python is installed from a package manager.

Anyway, I would download boost from the boost.org website. Then you will get a copy that's definitely not broken.

Thanks for the fast response. That worked like a charm.
