Hi Raman,

the issue is not with the function emacspeak-wizards-toggle-yyyymmdd-date-prouncer, but rather with the variable used to store the setting emacspeak-wizards-toggle-yyyymmdd-date-pronounce. 

I have the autoload for the function and that shows up with the grep. However, running package-list-packages still generates the void symbol error for the variable. 

What I think is going on is that the code in emacspeak-packages uses the variable, but if none of the autoloaded functions from the emacspeak-wizards file have been run prior to executing the package-list-packages function, the emacspeak advice in emacspeak-packages.el fails because the defvar for emacspeak-wizards-toggle-yyymmdd-pronounce has not been evaluated. As soon as you run one of the emacspeak-wizards autoloaded functions, the file is loaded and the defvar is evaluated and all is well. . 

This would explain why Bart was able to solve the issue by explicitly loading emacspeak-wizards and I was able to resolve it by ensuring an autoloaded function from emacspeak-wizards is run during my startup hook. 

To reproduce this issue, do

make clean, make config and make emacspeak

Modify your emacspeak init to ensure none of the autoloaded functions from emacspeak wizards are run during startup.

Run M-x package-list-packages as the first command you execute after startup initialisation has finished.

It looks like emacspeak-package.el is the only file other than emacspeak-wizards.el which has a reference to the variable emacspeak-wizards-yyyymmdd-date-pronounce, so an easy fix would be to put a require for emacspeak-wizards into emacspeak-package, but that feels a bit kludgy and would not stop a similar error should the variable be used in another file later on. I don't know if you can have autoloads for variables - I've only used them for functions and macros.

Tim

This definitely should be handled by the autoload cookie which is
present.

make config at my end does result in this line showing up in
emacspeak-loaddefs.el -- do   do this grep  on your end after make
config:

grep emacspeak-wizards-toggle-yyyymmdd-date-pronouncer emacspeak-loaddefs.el
(autoload 'emacspeak-wizards-toggle-yyyymmdd-date-pronouncer "emacspeak-wizards" "\

This makes me think that something in emacspeak-packages.el is relying on the variable in emacspeak-wizards.el, but there is no check that the file has been loaded, ensuring that the required binding has been defined. This would also mean that the chances of encountering this issue depends on how long emacspeak has been loaded and what commands have been executed prior to running package-list-packages. As my workflow is to check for updated packages right after starting emacs and before doing much else, I normally would not have run anything from emacspeak-wizards which would have loaded that file.
