ox-gfm package install warning

Question

When I install ox-gfm package, I got below warning:

Leaving directory ‘/Users/root/.emacs.d/elpa/ox-gfm-20170304.1504’

Compiling file /Users/root/.emacs.d/elpa/ox-gfm-20170304.1504/ox-gfm.el at Mon Apr  3 22:11:54 2017

Warning (bytecomp): reference to free variable ‘info’
Warning (bytecomp): org-export-collect-footnote-definitions called with 1
argument, but requires 2
Warning (bytecomp): org-html--anchor called with 4 arguments, but accepts only
0-3
Warning (bytecomp): the function ‘org-export-get-reference’ is not known to be
defined.

But sounds like org-export-get-reference will be used in publish code, so when I try to publish org file to md file (refer to this link), it will report a error:

org-gfm-format-toc: Symbol’s function definition is void: org-export-get-reference

So I guess we should not ignore the warning! Not sure if any other depend package missed!

My emacs version on MacOSX 10.12:

Seems like you should upgrade to a newer version of Orgmode.

Call org-version and see what you get. If it's something like 8.2, you should upgrade to 8.3 or higher. See the Orgmode package repo.
