I was following instructions here, specifically doing package-install counsel which it says will pull in ivy and swiper as dependencies (which it seemed to). However Counsel threw off these errors:
Warning: the following functions are not known to be defined: elisp-eldoc-documentation-function, elisp-completion-at-point, directory-files-recursively, irony-completion-candidates-async, irony-completion-symbol-bounds, irony-completion-annotation
Everything else looked alright, except for Swiper throwing a Warning: Unused lexical variable 'inhibit-message'  which didn't seem to me like as big of a deal. But what do I know?
Happy to provide full log, or anything else needed.
This was version 0.10.0 from MELPA Stable just now. GNU Emacs version from Help is: GNU Emacs 24.5.1 (x86_64-pc-linux-gnu, GTK+ Version 3.22.11) of 2017-09-12 on hullmann, modified by Debian
Note 1: actually a backtick before inhibit, but I couldn't figure out how to escape it out here on Github.
The text was updated successfully, but these errors were encountered:
Both sets of warnings (actually, there should also be a warning about minibuffer-keyboard-quit in your byte-compilation log) are known and due to ivy.el, swiper.el, and counsel.el making use of features not present in your Emacs version.
The warning about inhibit-message (which was added in Emacs 25.1) is harmless, as lexically binding an as-of-yet unknown and subsequently unused variable has no effect. By using an Emacs version without inhibit-message, it's likely you'll have some messages appear in the echo area at inconvenient times, but nothing will break.
The first three counsel.el warnings are due to #1579. The rest are due to the byte-compiler not knowing whether functions from an external package are actually defined. The calls to declare-function (see (elisp) Declaring Functions) are there, but appear after the calls to the corresponding functions. In other words, the byte-compiler in Emacs 24.5 emits warnings too eagerly. I'll submit a PR fixing this shortly.
P.S. Debian Stretch (current Stable) has been packaging Emacs 25.1 for a while now; I recommend upgrading to it if you're able to, as it comes with many important fixes and improvements, and many external packages either don't care much about or don't support earlier versions.
