Symbol's function definition is void: org-babel--get-vars

[ghost]

I am using Emacs 25 (compiled from source) and org-mode (release-8.3.4)

When I try code block as below:

#+BEGIN_SRC go
  fmt.Println("Hello World!")
#+END_SRC

I got error: "Symbol's function definition is void: org-babel--get-vars"

When I install org-mode from master branch, it works fine.

Strange... I'm using org-mode 8.3.4 (but with emacs 24.5) and symbol org-babel--get-vars exists. We already have a compat function called org-babel-go-get-var to handle compatibility with older org-mode (< 8.3).

https://github.com/pope/ob-go/blob/master/ob-go.el#L187

I had a similar problem, but for 'org-babel-get-header not defined` in 8.3.3 and then I added this compat function to solve the problem. At that time I found this link:
https://lists.gnu.org/archive/html/emacs-orgmode/2016-01/msg00468.html

I don't know what to do here... The release notes of org-mode 8.3.[3,4] doesn't say nothing about org-babel-get-header/org-babel--get-vars, but the master branch (or 9.0 release notes) do say to avoid org-babel-get-header and use org-babel--get-vars instead:
http://orgmode.org/cgit.cgi/org-mode.git/tree/etc/ORG-NEWS#n367

As I'd said before, I think the best way to guarantee this package working across orgmode versions should be submitting it upstream...

org-babel-get-header is defined for me.

org-version output:

Org-mode version 8.3.4 (8.3.4-79-gbd4948-elpa @ /usr/local/google/home/igm/.emacs.d/elpa/org-20160606/)

org-babel-get-header not defined here.

Hmm, just figured out that my org is not a released version of orgmode 8.3.4 but a cloned git repo... It says 8.3.4 in (org-version) but it was the master branch of March 14 2016 ...

Sorry about that.

@pope The function org-babel-go-get-var is really wrong... Instead of using org-version to decide between get-header/--get-vars better to only verify if org-babel-get-header is defined and use org-babel--get-vars otherwise...

Maybe check if function is defined is better idea than checking version number at here.
