When I byte compile an elisp file via emacs -batch -f batch-byte-compile I get Warning: load-theme called with 2 arguments, but accepts only 1. The code in question:

(load-theme 'solarized-light t)

The source in Emacs 25.1's custom.el: (defun load-theme (theme &optional no-confirm no-enable) ...

Similarly I get set-frame-font called with 3 arguments, but accepts only 1-2 when set-frame-font's help says: (set-frame-font FONT &optional KEEP-SIZE FRAMES)

Which is confused, the byte compiler or I; and why?

    I created a one line file with your first example in it. It compiled without a hiccup. There must be something more going on here. I don't think anyone can help without a little more detail. Oct 2, 2016 at 16:46

A guess would be that you are byte-compiling in an older Emacs version, which does not support the additional arguments.

For example, if you byte-compile with Emacs 23 then you will get such warnings, because those args are not supported.

  • Nope; this is in Emacs 25.1. This was happening in Emacs 24 too and I just ignored it then. But as long as I upgraded / was pruning my emacs initialization I thought I'd ask. Given @harald's comment I guess I am going to have to dig deeper.

  • Do you see the bad behavior when you start Emacs using emacs -Q (no init file? If so, consider reporting a bug, providing a step-by-step recipe: M-x report-emacs -bug. If not, recursively bisect your init file to find the part that causes the problem. You can use command comment-region to comment out 1/2, then 3/4, 7/8,... of the file. Use C-u with the command to uncomment the region.

  • Well, this was happening in my init file, which through decades of habit I byte compile.

  • Actually in what my init file would normally contain, which through decades of habit I byte compile and keep in a separate file while my actual init file just loads that file.) I 'fixed' the issue by simply removing the problematic lines that were related to old, pre-custom cruft anyway.) If I discover the actual cause I'll post that here.
