LD_LIBRARY_PATH failed in finding .dylib with macOS 10.12

[hangg7]

Hi all,

I was recently building shogun down in my mac (with macOS 10.12).

When I ran this command

$ clang++ -std=c++11 path/to/native_example.cpp -o path/to/native_example -I/path/to/headers -lshogun

I encountered a problem when setting LD_LIBRARY_PATH failed in finding the linker (-lshogun)

I finally solved it by export LIBRARY_PATH instead referred to here.

Don't know why, but seems worth to report in case of future macOS users getting stuck for days like me.

See also #3677, which I really think should be mentioned in README.

@cullengao this is very basic compiler flags. and i would rather suggest you to use -L<path to the lib folder where you installed shogun> instead of LIBRARY_PATH....

but anyhow if you feel that this is something that is missing there's the https://github.com/shogun-toolbox/docs repo and send in a PR

and btw on mac there is no LD_LIBRARY_PATH... it is DYLD_LIBRARY_PATH

@vigsterkr Thanks for being so swift to reply. To be honest, I used to work mostly on Python and rather new to compiler stuffs.

Glad you bring up DYLD_LIBRARY_PATH. I've actually tried but got no luck. Any thoughts? Would be happy to learn.
