Getting these error messages whenever I start up emacs:

[trackrise]

Warning (bytecomp) : reference to free variable 'predicate'
Warning (bytecomp) : reference to free variable 'inherit-input-method'
Warning (bytecomp) : reference to free variable 'ido-cur-item'
Warning (bytecomp) : reference to free variable 'ido-default-item'
Warning (bytecomp) : reference to free variable 'ido-cur-list'

I don't know why this is coming up, but I've traced it to this file:
C:\Users\User\AppData\Roaming.emacs.d\elpa\ido-ubiquitous-20140526.1306/ido-ubiquitous.elc

Hi @trackrise,

I'm having the same warnings as well inside the compile-log window but I'm using a Mac environment.

I found the solution here by @dudebout
DarwinAwardWinner/ido-completing-read-plus#35

where you need to define those variables first before defining ido-ubiquitious inside init.el.

I don't know how pull requests work here in github at the moment, but I will upload my updated init.el here in this comment.

I basically just followed the solution and declare those variables.

Just copy the content of the init.el below and update yours and see if it works for you.

Don't define those vars yourself!

Those vars about ido package and it's OK, you had 3 choices:

1. let them go;
2. use defentive code, fix that in your own .el file.

(if (not (boundp 'xyz))
   (setq-default xyz 123)))

3. pull a stable and flexible fork (support darwin, linux and windows, terminal or gui)

# 1. backup you ~/.emacs.d first
$ mv ~/.emacs.d <somewhere>

# 2. clone the fork, first close your Emacs
$ git clone --depth=1 --branch=master https://github.com/junjiemars/.emacs.d.git

# 3. start Emacs and wait for auto install some basic packages

I still have issues after the above solution:

emacs --debug-init

entered--Lisp error: (void-variable g)

less verbose is the error / warning about the init.el file:

Symbol's value as variable is void: g

I don't know enough about Emacs / Lisp to track this down apart from opening the init.el file but I cant really trace the error.

The emacs setup section is pretty well out of date, so Im trying to hack in the changes with the latest mac emacs, but there is a whole host of issues. Perhaps an update to this section. For now Im using another editor as I cant fix these Emacs issues, and there are no solutions yet.
