Emacs 25.1: Symbol’s function definition is void: x-selection-owner-p

I set up a Xubuntu 16.04 VM and compiled Emacs 25.1 using the instructions here https://www.emacswiki.org/emacs/EmacsSnapshotAndDebian#toc3, ie

sudo apt install autoconf automake libtool texinfo build-essential xorg-dev libgtk2.0-dev libjpeg-dev libncurses5-dev libdbus-1-dev libgif-dev libtiff-dev libm17n-dev libpng12-dev librsvg2-dev libotf-dev libxml2-dev
cd emacs
./autogen.sh
./configure
make bootstrap
sudo make install

but I don't get that error - how is your system configured?

ah, ok, so i'm on a OSX and i'd been using homebrew to install/configure the cocoa app. I tried both emacs-mac and emacs-plus

when on emacs-plus for emacs 24.5 everything works fine, but when i switched to emacs-mac (emacs 25) or the latest emacs-plus (emacs 25). Then I get the x-selection-owner-p issue

Okay thanks - #7 was the same issue - I don't have a Mac to test with but I think I got it set up correctly - it'll be updated when Melpa next builds it.

fixed as far as i'm concerned #13

I changed the code a bit to turn off a compilation warning - it looks like this now -

;; handle renamed function - x-selection-owner-p was renamed to
;; gui-selection-owner-p in emacs 25.1
(defalias 'selection-owner-p 'x-selection-owner-p)
(if (fboundp 'gui-selection-owner-p)
    (defalias 'selection-owner-p 'gui-selection-owner-p))

So if gui-selection-owner-p is available as in 25.1 it should use that.
