Execute Emacs command with root privilege.

Execute Emacs command with root privilege.

[Hongyi Zhao]

In Emacs, when I issue the 'M-x TeX-auto-generate-global' command
after loading AUCTeX, the followng error will be triggered:

TeX-auto-store: Opening output file: Permission denied,
/usr/local/var/auctex/amsppt.el

Is it possible to enable the root privilege for executing the above command?

It seems like auctex wrote or wanted to write something in system's
directory /usr/local/var/auctex/ but it could not.

Instead of root privilege you should maybe verify that you have write
permissions to that directory.

Does directory exist? Verify if it is there.

You're right. The following commands will fix this problem:

$ sudo mkdir  /usr/local/var/auctex
$ sudo chown werner:werner /usr/local/var/auctex/
